The printer purchase and maintenance
Classification - three models
There are various types of printers, is the choice of needle, laser or inkjet printer depends on the specific use. In general, use the stylus printer cost is relatively low; from the print quality and speed, ink-jet and laser printers are much better than stylus printer. Stylus printer is a special place where it can print multi-layer paper, printing paper only in the selection of stylus printer, to put up with some of the noise. However, in our home users of personal choice, it would generally be excluded.
Good quality laser printer, printing costs are also lower than the ink-jet printers. But more expensive laser printers, at least take a few thousand dollars, or even million, several million are not unusual, but in general most black and white (very high-color) can not print color documents. The ink-jet printers from all the high-end to low-grade, suitable for a variety of levels. The average family to buy low-to mid-range inkjet printers and more. So here we are focused on the ink-jet printer to buy the brand and knowledge.
Brand - one-third of the world
Ink-jet printers in the domestic market are Canon, Epson and Hewlett-Packard three, individual characteristics of each printer. From the print image quality, mid-range of low (for family) in the printer to Epson printers for the good; from the cost of printing, Canon's slightly lower. From a technical point of view principle, Hewlett-Packard and Canon is used in bubble-jet printing technology, characterized by more mature technologies, the head of the lower cost of production and use of color cartridge nozzle design, for the DIYer who, directly It is easy to increase the benefits of casual Mexican. However, the technology of its decision to print resolution (dpi) can not be very high. But Hewlett-Packard and Canon have adopted a number of resolution enhancement technology (PhotoREt, adjusted drop, multi-color control, etc.), to a large extent made up for this deficiency, the user can not be too concerned about the actual value dpi. Epson used its unique micro-voltage control technology, which is characterized by easy reach of high-resolution printing (720dpi and 1440dpi), with its unique ink technology, can improve the effectiveness of photo printing. But the disadvantage is that its head is too sophisticated and protective measures are not effective, easy to improper use of a failure. In addition the cartridges separation nozzle design, so if the use of non-original ink need to address.
Use - a variety of factors affect the quality of
The depth of color printing control, provided by the manufacturer of color paper and printing quality will have an impact. Color depth control of different images, the more levels, more realistic effect of different vendors to provide the color print of the image is different; paper of different image quality will lead to great differences. As the special paper and printing paper price vary greatly in general, the general in print before the official releases there is no need to use special printing paper.
In addition, the printer cartridges are also affecting the quality of printing. Caipen upscale image than the excellent mid-range aircraft, mainly due to more use of color ink. Printer to print out colorful graphics are different colors mixed into the ink. Is the first of three color mixed, but the result was not good, then use the green, yellow, magenta and black four-color, the color of the control strengthened, and professional print, but not compared to the results, then combined with TANSEI , One of two color magenta light to improve the effectiveness of the region.
For individual users, color ink-jet printer to buy the times, it is easy to lose sight of the cost of using the printer problem. In fact, this issue is very important, imagine you bought a printer to print 10 will be spending a cartridge, and an original ink to spend more than 100 yuan, strange if you do not feel bad.
To reduce the cost of printing there are many methods, such as: text and images were used to separate black and white and color print cartridges, does not apply to this method now widely used in color graphic documents Mixed; using plain paper printing, although the effect will almost , But not as long as an official document, not a big problem; the use of re-injection of ink can greatly reduce the cost of printing, but the resulting problems are not factory warranty, must think twice before taking any action.
To buy - must be value for money
Have a thousand dollars or so to go home Caipen can not pick a pair of slippers. Do not have to value for money, but it must be value for money. Caipen low price at 900 yuan for some of the images do not require too high, some of the occasional fight color of the user works. If you require a higher output image, the choice Caipen mid-range price of about 1,500 yuan. Caipen is the real high-end photo printer level, is the first choice for fine arts workers, the effect can be comparable with the laser printer.
For individual users, Caipen the printing speed is not important is the need to pay attention to the quality of printing and printing costs. The Canon cartridges are ultra-high-capacity and print the economy; in the Epson print quality is excellent; Hewlett-Packard emphasized in the ordinary print photos on paper to achieve the output level.
900 yuan a file of the printer has its own unique features, though less expensive, but the print is not satisfied with the photos; mid-1500 yuan or so although there are some mixed images and moving images like a minor point. But for non-professionals to say, enough satisfied.
It has been estimated that Hewlett-Packard, the world of full-function office equipment needs and market potential, up to 144 million dollars. The large staff of the home, SOHO caused by the growing family of the prosperous and thriving. From the history of the evolution of science and technology, the machines more integrated functions, saving the user more time to become inevitable.

Examples of printer paper fault maintenance
Stylus printer printer paper is the branch of the stylus printer is also an important applications, mainly in the banking, insurance, industrial and commercial tax and securities industry. This printer has a simple, low-cost printing, mature technology and so on. And other office equipment, due to the frequent use of printer paper and more prone to failure, especially in the first print mostly failure. The following for you to print the first control problems with the drive circuit failures.
The first print control and drive circuits caused by the failure of the main phenomenon in three respects: First, the odd or even number needle acupuncture needles can not, the result is a character printing / severely deformed characters; Second, a number of print for a needle or pin or some individual Print print when no needle injections, the result is a print character / characters of the regular shortcomings less draw, that is, his character / characters in one or more white lines, as well as print characters / character point line together, that is, his character There are one or a few black lines, there will be serious when printing pin was to hang up. Third, we can not print all the needle acupuncture, print the page does not print writing.
First, print head fault control and drive circuits of the reasons
It should be said that various models of printer paper in the overall design is not very different, but some of the specific printer paper and the structure of the circuit is still a certain degree of difference. Therefore, the following general analysis of the first and the reasons for these failures.
1. Acupuncture needles can not print all print
All-pin printer to print bills in print when the needle was not printed, printing was mainly attributable to needle driver coil no incentive to exert high pressure so that the needle does not print the driving force rather than a needle. In addition, some bills have a specially designed pin printer data to form circuits, such as DLQ-2000K, if the first print driver HPW pulse signal failure, the needle will be unable to print to be inspired and the emergence of high-pressure needle can not print all the print needle phenomenon . Another example is the OKI-5330SC printer paper, and is to SERIALCLOCK-N signal synchronization of serial data SERIALDATA-N into the first printing of the needle parallel data signal HEADDATAl ~ 24, SERIALCLOCK-N or SERIALDA-TA-N signal failure , The needle can not print all the print needle.
2. Odd or even number needle acupuncture needle can not print
Some printers, the print head control and drive circuits designed to allow odd-numbered pin signals and even allow the signal pin. In such a design of the printer, only when the signal to allow effective needle odd, odd-numbered pin will it be possible to print out the needle; and even when the juice to allow an effective signal, the needle can even print out the needle. If the odd or even number needle acupuncture needle can not print, testing should be odd or even-numbered pin pin signals whether or not to allow normal. Such as OKI-5330SC, the print head control and drive circuits designed to allow odd-numbered pin signal ODD-EN needle and even allow the signal EVEN-EN.
3. Print part of the individual or needle acupuncture can not print
When the needle to form the data circuit (or circuits dedicated gate array) and circuit Driven pin print individual devices in a part of the damage, it will cause a partial or no acupuncture needle printing individual print. In some printer paper, the incentive is a sub-four-way high-pressure needle to the print driver provided by the coil (such as the AR-5400, AR-6400 paper in the printer to print can be divided into four needle coil incentive to exert high pressure, and the Lexmark 2391Plus paper in the printer is Fensan Lu-pin printer driver for the module to provide the high-pressure). In this form of circuit, which damaged all the way from those it provides high-voltage pin (6 or 8) will not be able to print out the needle. In general, when the printer paper in the print process, the rules have less to 6 or 8-pin failure of this phenomenon, it is possible that this is three or four in a road damage. Therefore, in this type of examination fault circuit should be based on the specific printer paper's print pin driver circuit analysis and testing, the last to find out the damage to the device and be replaced. In addition to print output in the first cable outlet will also be bad for the first printing of individual print needle acupuncture can not print.
E05A02LA chips used in acupuncture as a form of data circuits DLQ-2000K printer paper, as a result of E05A02LA chip 8-line data entry in each of the 3 controls the printing of the needle-pin data signals (E05A02LA chip specific analysis of the circuit, see the back Examples of the circuit), when the machine interface circuit of the 8-bit data input line in a certain way (break) or short-circuit, with its corresponding 3-pin will not be able to pin out of print, print out the character / characters The three will appear on the white lines; 3-pin or needle in a row out of print, print out the character / characters appear on the three black lines (printing Chinese characters at this time will not be accompanied by on-line print, but when a lot of self-print Needle. Therefore, this inspection should also be noted that failure to check their interface circuit).
Second, the print head control and drive circuits to deal with examples of failure
One example: DLQ-2000K printer self-test paper when printing print character shortcomings less draw
Trouble is: DLQ-2000K self-printing paper when the printer to print out shortcomings characters few designated incomplete.
Troubleshooting: The characters from the print / draw characters fewer disadvantages of this phenomenon, caused by failure of the reasons there may be four: first, the print head to print a broken needle; Second, the print driver needle coil or open burn ; The third is to connect the first printing of the decapitation appeared on cable or plug and socket between the individual bad pins; fourth, the first print driver and control panels have a failure. First of all, with the first printing Duanzhen testing procedures to test for the first print out the needle print, the results measured, 5,13,21 needle acupuncture can not print. The following steps according to the diagnosis and rule out:
① power to close the printer, the word will be moved to the car in the middle, followed by ribbon cartridge removed and the first print from the print head in front of the first print-oriented on-board inspection whether Duan Zhen, the results have not found Duan Zhen.
② multimeter with carefully measuring each print head of the DC coil resistance, the resistance value measured in line with the normal value.
③ check printing in the first cables to connect the pins is bad, no problem. Open the top printer from the printer to print on the right side of the first cable outlet on the board off three flat cable, pen table Multimeters the two were up in the search cable (a total of three cables, two wide print head for the cable, the most The sensor is a narrow ribbon and the motor-driven cable signal) corresponds to the two ends of the line, measuring its resistance value is zero, the measured results of the short-pin cable to connect the first group of 9 broken foot, the same model with a flat cable replacement After troubleshooting.
Failure Analysis: DLQ-2000K printer paper's print head pin short drive coil group is the first line of 9-pin, 5,13,2 l coil power of public input side, which is the root along the printer cable is directly outside the rack In a special plug socket, 3 of the cable outside and covered with a piece of metal protection. As the rack, and the most short-pin cable group coil obvious contact with the lower end of the edges and corners, just stuck the cable bending parts. Long-term friction will be the first cable 9 mill off-line, which would result in serious root on the line to short-circuit, that is, +35 V power supply side of the rack to short-circuit the whole circuit of the master printer paper work.
The first print control and drive circuits caused by the failure of the main phenomenon in three respects: First, the odd or even number needle acupuncture needles can not, the result is a character printing / severely deformed characters; Second, a number of print for a needle or pin or some individual Print print when no needle injections, the result is a print character / characters of the regular shortcomings less draw, that is, his character / characters in one or more white lines, as well as print characters / character point line together, that is, his character There are one or a few black lines, there will be serious when printing pin was to hang up. Third, we can not print all the needle acupuncture, print the page does not print writing.

2. Odd or even number needle acupuncture needle can not print
Some printers, the print head control and drive circuits designed to allow odd-numbered pin signals and even allow the signal pin. In such a design of the printer, only when the signal to allow effective needle odd, odd-numbered pin will it be possible to print out the needle; and even when the juice to allow an effective signal, the needle can even print out the needle.

Although many models of laser printers, but because of its working principle and use of the materials are essentially the same, just some different specifications, so the laser printer for general maintenance, can be basically suitable for all kinds of laser printers, but there are some special The only difference.
1. Electrode wire maintenance
Due to a printer, there are remnants of toner, dust and debris, such as confetti, charge, transfer, separation and anti-electric wire electrode will be contaminated, so that the voltage drop in normal performance. In general, if the charge, the electrode wire transfer of soiled Feifen, Zhihui, and so on, will print out the lack of color printing job, or even very short, largely as a result of dirty electrode wire after charging less than the cartridge It generated in the cartridge on the latent image of sufficient voltage and smoke less toner, the electrode wire transfer contaminated by enough voltage, when the paper through the paper so that when the cartridge and contacts close enough, by transfer Not enough toner to the paper, it will make the output of color pattern Taidan. In addition, the electrode wire transfer (slot) will also cause serious pollution, and the output pattern on the back of dirty, as the output pattern to be gone through at the electrode wire transfer slot. And eliminate pollution from electric Electrodes make poor separation of paper and cardboard, and so have a failure
Eliminate pollution from electric Electrodes on the cause of residual toner cartridge is not a clean sweep, so that the output of ash at the end of a serious pattern. The maintenance of electrode wire should be carefully remove the wire electrode assemblies (number of aircraft models of printers do not have to remove the wire electrodes directly on the machine in the clean-up), the first of its Shuadiao brush attachment on the foreign body, followed by cotton and then spend their Gently wipe clean carefully.
2. Laser scanning system to maintain
When the laser scanning system of lasers and mirrors to be the work of all kinds of dust pollution, and so on, will result in increased print-gray at the end, clear images. Cotton flowers can be used to wipe them clean, but should be careful not to change their original location or Peng Huai.

Canon ink-jet printer completely DIY Manual
For a long time, Canon inkjet printers complete DIY manual stylus printer has been half of the domestic printer market, because of its reliable, affordable and can use ordinary paper, cheap supplies and a significant reduction in the cost of the user, but also be able to print more A sense of laminated paper, at the same time can be more than a copy of the print in order to enhance efficiency, so most users will print their slow, noisy, bulky size, and so turn a blind eye to the shortcomings. With laser printers, ink-jet printer technology continues to mature, production and marketing of the increasing size and gradually reduce the cost of bringing declining at a competitive price, per thousand this time around because of the color ink-jet printers are small , Light weight, speed, low noise, fine print quality, color support, such as the advantages of low cost, rapid access to the area of small home office, computer peripherals and is becoming the preferred configuration.
However, the ink-jet printer supplies there are still shortcomings expensive, making a large number of print far more than the cost of laser printers, and the text of a large number of print and office applications is just one of the main characteristics. So how to reduce the cost of running the ink-jet printer has become a vast number of users to issues of primary concern.
Original expensive ink for ink-compatible manufacturers to provide a living space, many users choose to turn to compatible ink. At this time, another vexing problem has arisen, ink-jet printer manufacturers out of various considerations, often a warning users not to use compatible ink, the printer in order to avoid failure, and users to buy and use compatible ink in the process, and indeed the event To a number of problems, the use of compatible ink feasible? Compatible ink can effectively reduce the consumption of ink-jet printer?
First, the selection of ink-jet printer
If you want to reduce the cost of printer supplies, it is necessary to proceed to consider when buying a printer. The important aspect is often overlooked by many DIY customers.
In fact the selection of the printer determines the two points: First, the choice of ink, the printer is the choice of maintainability.
The working principle of ink-jet printers To put it simply, through the small print head nozzles in the cartridges will drop slightly to the jet, and other media on paper to form a lattice drop and pose a variety of text or images.
1. Inkjet print head and printer relationship
By different manufacturers in the first ink-jet printer to print the design is not the same, and some will be installed in the fuselage for the first printing of small cars, with the print cartridges in the first set separation, when the ink cartridges run out just when the replacement cartridges can be. The main advantage of this design is the print head delicate position adopted by the manufacturers of fixed-adjusted, to achieve high-precision high-resolution printing, as manufacturers publicity is no need to replace the print head, only to replace the cartridges can save the cost of supplies that, because of original Supplies and high prices appears to be a bit of water.
The shortcomings of this structure is that once the first printing of serious failures, ordinary users usually can not be dealt with only through a general settlement of repair and maintenance costs may be higher (in this case can be made public a secret: It is not willing to publish the identity of the people from this sector, with The structure of a certain brand of inkjet printers, almost totally dependent on the user's maintenance fees to generate a profit, because the repair cost to replace the print head up to a few hundred yuan, almost the purchase of a low-grade color ink-jet printers close to the price.) Generally The home users, DIY enthusiasts consider the best.
Another is to design and print the first printer independent of each other, and the first print cartridges and the relationship can be separated or combined into one. This design has the advantage of an ordinary user can bare hands demolition, installation, replacement print head, in the event of irreparable plug nozzle failure, users only need to buy a new print head, to be replaced in order to save the expensive maintenance costs.
To improve the maintainability of this design is very clever and worth learning: through the user's own replacement cartridges or problems with the print head, omitted the first printing factory maintenance process and simplify the maintenance of the printer difficult. This is in fact the manufacturers will repair technology transfer to the user's clever strategy to become the first printing factory maintenance of the user's own replacement print head.
Of course, this is a kind of print quality and cost of printing a compromise design, as the print head can be replaced, in contrast to the previous designs, is bound to reduce the positioning accuracy of the print head, in the resolution of losses. Of course, this is the first theoretical comparison, in the rapidly-resolution inkjet printers today, for the small home office users, not necessarily the naked eye can tell the difference, especially when taking into account the maintainability of priority, it may not be About the difference. In addition, due to the compatible ink made in recent years has improved the quality of, for advertising design, wedding photography, such as ink consumption of large business users, is gradually made to adopt and accept the ink, ink compatible with a local distributor to carry out on this A door-to-door business.
2. The structure of the ink-jet cartridges
Canon ink-jet printer cartridges, there are two main structures: One is the print cartridges and the first one to create such structures have a black high-capacity cartridges of the BC-20, a color photo cartridge BC-22e (Figure 1). When the ink consumption has been completed, the entire cartridge must be replaced, as the ink-jet printer is a key part of the print head, so the integration of the high cost of ink cartridges; and the other is the print cartridges and head separated from the cartridge is the model BC-21e , With the exception of the first printing, but also contains two separate small print head cartridges, color BCI-21C (with red, yellow and blue ink), black BCI-21B (Figure 2). When the ink cartridges in the depleted, they can only replace the cartridges, designed to avoid such a frequent replacement of expensive print head, thereby reducing the cost of running the printer.
The design of two cartridges each length: Although the design of the cartridges expensive, but simply through the replacement cartridges can print to ensure satisfactory results, greatly reduced the cost of maintenance of printers and more difficult. In other words, the manufacturers designed to be so interested in maintenance-free: When a user might feel the print quality, ink in the ink has been almost exhausted, this time to replace cartridges integration not only be able to provide adequate ink, Logical replacement of a new print head, so as to maintain the stability of the print quality, so most of Canon products using such designs. It should be pointed out here: As the manufacturers of brand-name printer exquisite manufacturing process, as long as proper maintenance, in the ink cartridges run out in the first print does not mean the inevitable end of life, not even the first printing will cause an inevitable decline in the quality of output, which is cartridges The use of renewable sources of the fundamental conditions.
Separation design reduces the cost of ink, but the specifications of inks higher if the replacement cartridge is not high quality, it is easy to plug the print head nozzles, resulting in print quality, will cause severe end-of-life print head, so the manufacturers recommendations The best use of original cartridges.
At this point, on the selection of the printer can make a conclusion: to buy a printer and print head separate models (actually a user can purchase their own models to replace the print head), such as models of the highest maintainability, Once the print cartridges or scrapped in the first, users pay only a Yier Bai million new cartridges, but by no means possible repair a printer equal to buy printers joke.
Technically, if users need to print color photos, at least to the purchase of four-color printers, ink is contained in the black, red, yellow and blue colors of the four ink printers. If the three-color printer, color ink cartridges when printing black when three synthetic colors, not economic, print speed will be reduced, so no consideration will be given.
The Canon printer series, recommended the purchase of mid-range BJC-4310SP, are: four-color printers, ink cartridges models complete, print speed, high-quality images (and not a public advantages: particularly suitable for DIY users to ink perfusion).
However, the ink-jet printer supplies there are still shortcomings expensive, making a large number of print far more than the cost of laser printers, and the text of a large number of print and office applications is just one of the main characteristics. So how to reduce the cost of running the ink-jet printer has become a vast number of users to issues of primary concern.

Although many models of laser printers, but because of its working principle and use of the materials are essentially the same, just some different specifications, so the laser printer for general maintenance, can be basically suitable for all kinds of laser printers, but there are some special The only difference.
1. Electrode wire maintenance
Due to a printer, there are remnants of toner, dust and debris, such as confetti, charge, transfer, separation and anti-electric wire electrode will be contaminated, so that the voltage drop in normal performance. In general, if the charge, the electrode wire transfer of soiled Feifen, Zhihui, and so on, will print out the lack of color printing job, or even very short, largely as a result of dirty electrode wire after charging less than the cartridge It generated in the cartridge on the latent image of sufficient voltage and smoke less toner, the electrode wire transfer contaminated by enough voltage, when the paper through the paper so that when the cartridge and contacts close enough, by transfer Not enough toner to the paper, it will make the output of color pattern Taidan. In addition, the electrode wire transfer (slot) will also cause serious pollution, and the output pattern on the back of dirty, as the output pattern to be gone through at the electrode wire transfer slot. And eliminate pollution from electric Electrodes make poor separation of paper and cardboard, and so have a failure
Eliminate pollution from electric Electrodes on the cause of residual toner cartridge is not a clean sweep, so that the output of ash at the end of a serious pattern. The maintenance of electrode wire should be carefully remove the wire electrode assemblies (number of aircraft models of printers do not have to remove the wire electrodes directly on the machine in the clean-up), the first of its Shuadiao brush attachment on the foreign body, followed by cotton and then spend their Gently wipe clean carefully.
2. Laser scanning system to maintain
When the laser scanning system of lasers and mirrors to be the work of all kinds of dust pollution, and so on, will result in increased print-gray at the end, clear images. Cotton flowers can be used to wipe them clean, but should be careful not to change their original location or Peng Huai.

Ink-jet printer cleaning and maintenance
Regular users must use the printer, the printer in use for some time, the printer will slow the pace, often even cardboard. In fact, these printers in addition to its own performance and aging equipment, there is the printer from external environmental factors. Such as dust, stains, broken, such as confetti, this is the impact printer performance and stability.
Therefore, printers require regular maintenance in order to make the printer to maintain a good working condition. Ink-jet printer the following day-to-day maintenance work.
Internal dust
We have to Canon's S450 Color ink-jet printer, for example, open the cover of the printer can carry out the work of dust.
Internal dust needs to be done for the following two aspects, one with soft, wet cloth to remove dust within the printer, stains, ink stains and broken confetti; Second, if too much dust will lead to poor lubrication shaft so that the print The first print campaign in the course of obstruction. At this time can be used dry erase sign cotton dust and lead axis of oil pollution (and to add liquidity better lubricant, such as sewing machine oil.
Finally, dedusting for ink-jet printers in-house, they should note the following:
(1) Do not wipe gear, do not wipe print head and cartridges in the vicinity of the region;
(2) do not generally move in the first printing, in particular some of the printers print head in a mechanical lock, the first print can not be moved by hand, by force if the force moving print head, causing damage to the mechanical parts of the printer;
(3) non-paper products (such as tissues) printers in-house cleaning, the residue inside the machine so as not to litter;
(4) can not use volatile liquids (such as thinner, gasoline, spray chemical cleaning agent) clean printers, so as not to damage the surface of the printer.
Replacement cartridges
Inkjet printer models, the use of replacement ink cartridges and the type of approach is not the same as that used in inkjet printers usually have a detailed description of the replacement ink cartridges, and in most of the printer cover are also equipped with a simple chart (see Figure 4).
Replacement cartridges, is really very simple operation, first of all, boot power to ensure the ink-jet printers, ink cartridges online, open the front cover, this time stent cartridges will be moved to the middle. And then open the printer top (see Figure 5), took out the old cartridges. Finally, open a new cartridge packaging, the new cartridge into the pressure tank, touch the top of the cartridge so that it can be a good contact.
Replacement cartridges when they must operate in accordance with the manual steps, the printers need to open the power of the state of replacement ink cartridges, as replacement printer cartridges after the ink delivery system will charge Mexico. In addition to the printer's ink capacity measurement is the use of printers in-house electronic counter to the count, in the process of replacement ink cartridges, printer to its in-house electronic counter reset to carry out in order to confirm the installation of a new cartridge.
Replacement cartridges, please note the following:
(1) can not hand-to-exports of ink cartridges, ink cartridges to prevent the infiltration of impurities;
(2) cartridges to let light get light to prevent leakage of ink;
(3) with conductive ink, if the leak onto the circuit board should use ethanol (alcohol) wipe, and then dry power, or else they might damage circuit components;
(4) ink cartridges should be kept in the dark dust-free, should be preserved at the temperature -10 ℃ ~ 35 ℃ between.
Cleaning print heads
Most of the ink-jet printers will start self-cleaning print head, and there are buttons on the print head to do the washing. Some software can control the printer to print head cleaning, for example: EPSON STYLUS PHOTO 750 printer can not only control panel on cleaning key to cleaning nozzles can also be drivers bring their own use of the print head cleaning tool for cleaning. If after cleaning after several print head or plug, you can temporarily close the printer, start the next day when you print wash in the first, if the print quality did not improve on the printer cartridges has expired or has been damaged by the replacement cartridges to To solve the problem.
If the printer self-cleaning function is invalid, you can print on the first manual cleaning. Hand-washing should be manual steps in the demolition of the first printing. Hand-washing can be printed in the first set of front-end part of medical syringes thin tube, through strict filtering into the wash water, wash carefully with a magnifying glass to observe nozzle, spray, such as deposition hole next to the remnants of which can be used to remove soft products . Do not have to be shelved due to the integration of the first printing ink dried up and plug the nozzle can be used hot water and then soak cleaning.
Print head cleaning should note the following:
(1) Do not use sharp objects to clean nozzle, the nozzle can not hit, do not touch his hand nozzle;
(2) can not live in a state of demolition, the installation of sprinkler heads, hands or other objects do not contact the printer electrical contact;
(3) can not be unloaded on the printer nozzle from a separate place, the nozzle can not be placed on dusty places.
Therefore, printers require regular maintenance in order to make the printer to maintain a good working condition. Ink-jet printer the following day-to-day maintenance work.

Fixing the maintenance of the heating roller
Fixing heating roller in the long-term use may be attached layer of toner, in general, the heating roller surface should be very clean, dirty if it will affect the effectiveness of print. If you print out the emergence of Yang Gao black block, and, as well as by the sticky toner taken elsewhere, which means that the surface of hot roll has been injured or, if minor, cleaning can be used (but not for the sulfuric acid lost paper ), If serious, only the replacement of the heating roller. Heating and roll the rubber match of the roll, after the long-term use will be attached Feifen generally minor when the results will not affect the output, but serious, Yang Gao on the back of the output will become dirty. Clean heating roller and rubber roller, cotton can be spent carefully dip alcohol to wipe clean. But not too hard to clean heating roller, but should not use blades to scratch and Liverpool in order to avoid damage to the heating roller fixing. And the rubber roller can be simple and clean, simply wipe the surface clean can be.
Color printers use and maintenance
1, and the general principles of the proper use of
Color inkjet printers are similar to a stylus printer's output device, it is requested by the computer-generated print of the signal, and then by the printer nozzle in accordance with the different signals emitted ink, if the color ink-jet printer (usually black) , No matter what color graphic, the output is black, the color output, then converted to black to print the contents of the gray, the color of its conversion into a different color range, which is like shooting black and white photographs; As for color ink-jet printer, the red ink HUANG Lan and 4, according to the principles of the three primary colors, it can be synthesized all the colors of the image, according to a computer printer output to send signals to control the color of different colors of ink-jet cartridges, thus for the synthesis of Color samples. According to the characteristics of ink-jet printers work, it should be noted, a printer at work to ensure that there is a solid platform for work, not to be placed in the printer to the top of any article. In the printer to print to be shut down before the cover to prevent dust into the machine or other hard objects impede the movement of the car printer. Prohibition of live pluggable printer cable, it will damage the printer and the LPT parallel port of the computer motherboard, or even serious damage to the motherboard. If the printout is not clear, the printer can be self-cleaning nozzle cleaning function, but a small amount of ink consumption. If the cleaning several times in a row after the print was still not satisfied, at this time may have run out of ink, the cartridges need to be replaced.
2, environmental requirements
Ink-jet printers work environment if too much dust can easily lead to bad lubrication car guide axis, so that the first printing in the printing process or delay the movement of poor, so that it will cause a printer can print a specified location, so that the print By the content can not meet our requirements, or even the general image of the malformation, can not be used, in addition, if often blocked or severely impeded movement, but also caused damage to the printer. As a result, the work environment must be clean and dust-free, should also be necessary from time to time on the printer's cleaning and maintenance. In addition, when the print head can not be blocked and returned to the initial location of the restart, first of all printers will print head back to the initial position, and then will head to carry out the washing operation, the result in unnecessary waste of ink. The solution is often to wipe the dust off-axis guide, and guide shaft for lubrication, and better mobility can be used lubricating oil, such as sewing machine oil. In the process, carry out regular checks of the first printing of the movement and found that the issue be settled in time.
3, the cartridges maintenance
For ink-jet printers, ink cartridges is not only its main supplies, but also the most prone to failure of one of the site. Therefore, special attention should be paid ordinary cartridges used in the maintenance. In general, the use of cartridges has not finished, it is best not to take down to avoid a waste of ink or printer ink on the measurement error. In addition, before the shutdown, to return to the initial location of the print head (the printer in a state of suspended, automatic print head back to the initial location). Some printers (such as the Stylus Pro XL, MJ-1500K, etc.) in pre-shut down automatically moved to the first printing of the initial location, such as the MJ-800K, Stylus-1000, Stylus Color Ⅱ, and so must be confirmed before the shutdown Department The suspension of the state (that is, suspend or lamp lights Pause) can be turned off. The first to do so when they start next printer to avoid re-cleaning operation a waste of ink nozzles, and the other is in the initial location because the nozzle can be sealed to protect the hood, so that is not easy to plug nozzle. Therefore, in order to pay special attention to the ink-jet printer cartridges and head of maintenance.

Ink-jet printer maintenance knowledge
First, internal dust removal Information
Open the cover of the ink-jet printer can carry out the work of dust.
Needs to be done are mainly two:
1, with soft, wet cloth to remove dust within the printer, stains, ink stains and broken confetti;
2, if the dust will lead to too many characters lead vehicle axle lubrication is not good, so that the first print campaign in the print process blocked, can be used dry erase sign cotton dust and lead axis of oil pollution, and to add liquidity better lubricants Such as sewing machine oil.
Ink-jet printers for in-house when the dust:
1, not to wipe gear, do not wipe print head and cartridges in the vicinity of the region;
2, generally do not move in the first printing, in particular some of the printers print head in a locked state machinery (such as MJ-1500K, STYLUS COLOR printer, etc.), the print head can not be moved by hand, if the effort to force the first mobile printing, the printer will result in mechanical Some of the damage;
3, no paper products (such as tissues) printers in-house cleaning, the residue inside the machine so as not to litter;
4, can not use volatile liquids (such as thinner, gasoline, spray chemical cleaning agent) clean printers, so as not to damage the surface of the printer.
Second, the cartridges must be replaced
Replacement cartridges when they must operate in accordance with the manual steps. Printer ink on the capacity of the measures is to use the printer's internal electronic counter to the count, in the process of replacement ink cartridges, printer to its in-house electronic counter reset to carry out in order to confirm the installation of a new cartridge.
Replacement cartridges, please note the following:
1, not hand-to-exports of ink cartridges, ink cartridges to prevent the infiltration of impurities;
2, do not fall into the ink cartridges, ink to prevent leakage.
3, with conductive ink, if the leak onto the circuit board should be used alcohol wipe, and then Lianggan electricity, or else they might damage circuit components;
4, ink cartridges should be kept in the dark dust-free, should be preserved at the temperature -10 ℃ - 35 ℃ between.
Third, the print head cleaning Information
Most of the ink-jet printers will start self-cleaning print head, and there are buttons on the print head for cleaning, such as the Canon BJC-610 inkjet printer with the rapid cleaning, washing and thorough cleaning of conventional third gear cleaning function, specific cleansing operation Please refer to the ink-jet printer operations manual steps. If the printer self-cleaning function is invalid, you can print on the first manual cleaning. Hand-washing should be manual steps in the demolition of the first printing.
Hand-washing can be printed in the first set of front-end part of medical syringes thin tube, through strict filtering into the wash water, wash carefully with a magnifying glass to observe nozzle, spray, such as deposition hole next to the remnants of which can be used to remove soft products .
Do not have to be shelved due to the integration of the first printing ink dried up and plug the nozzle can be used to invade the bubble of hot water after washing.
Print head cleaning should note the following:

Examples of printer paper fault maintenance
Stylus printer printer paper is the branch of the stylus printer is also an important applications, mainly in the banking, insurance, industrial and commercial tax and securities industry. This printer has a simple, low-cost printing, mature technology and so on. And other office equipment, due to the frequent use of printer paper and more prone to failure, especially in the first print mostly failure. The following for you to print the first control problems with the drive circuit failures.
The first print control and drive circuits caused by the failure of the main phenomenon in three respects: First, the odd or even number needle acupuncture needles can not, the result is a character printing / severely deformed characters; Second, a number of print for a needle or pin or some individual Print print when no needle injections, the result is a print character / characters of the regular shortcomings less draw, that is, his character / characters in one or more white lines, as well as print characters / character point line together, that is, his character There are one or a few black lines, there will be serious when printing pin was to hang up. Third, we can not print all the needle acupuncture, print the page does not print writing.
First, print head fault control and drive circuits of the reasons
It should be said that various models of printer paper in the overall design is not very different, but some of the specific printer paper and the structure of the circuit is still a certain degree of difference. Therefore, the following general analysis of the first and the reasons for these failures.
1. Acupuncture needles can not print all print
All-pin printer to print bills in print when the needle was not printed, printing was mainly attributable to needle driver coil no incentive to exert high pressure so that the needle does not print the driving force rather than a needle. In addition, some bills have a specially designed pin printer data to form circuits, such as DLQ-2000K, if the first print driver HPW pulse signal failure, the needle will be unable to print to be inspired and the emergence of high-pressure needle can not print all the print needle phenomenon . Another example is the OKI-5330SC printer paper, and is to SERIALCLOCK-N signal synchronization of serial data SERIALDATA-N into the first printing of the needle parallel data signal HEADDATAl ~ 24, SERIALCLOCK-N or SERIALDA-TA-N signal failure , The needle can not print all the print needle.
2. Odd or even number needle acupuncture needle can not print
Some printers, the print head control and drive circuits designed to allow odd-numbered pin signals and even allow the signal pin. In such a design of the printer, only when the signal to allow effective needle odd, odd-numbered pin will it be possible to print out the needle; and even when the juice to allow an effective signal, the needle can even print out the needle. If the odd or even number needle acupuncture needle can not print, testing should be odd or even-numbered pin pin signals whether or not to allow normal. Such as OKI-5330SC, the print head control and drive circuits designed to allow odd-numbered pin signal ODD-EN needle and even allow the signal EVEN-EN.
3. Print part of the individual or needle acupuncture can not print
When the needle to form the data circuit (or circuits dedicated gate array) and circuit Driven pin print individual devices in a part of the damage, it will cause a partial or no acupuncture needle printing individual print. In some printer paper, the incentive is a sub-four-way high-pressure needle to the print driver provided by the coil (such as the AR-5400, AR-6400 paper in the printer to print can be divided into four needle coil incentive to exert high pressure, and the Lexmark 2391Plus paper in the printer is Fensan Lu-pin printer driver for the module to provide the high-pressure). In this form of circuit, which damaged all the way from those it provides high-voltage pin (6 or 8) will not be able to print out the needle. In general, when the printer paper in the print process, the rules have less to 6 or 8-pin failure of this phenomenon, it is possible that this is three or four in a road damage. Therefore, in this type of examination fault circuit should be based on the specific printer paper's print pin driver circuit analysis and testing, the last to find out the damage to the device and be replaced. In addition to print output in the first cable outlet will also be bad for the first printing of individual print needle acupuncture can not print.
Used as a chip in E05A02LA pin data to form the circuit DLQ-2000K printer paper, as a result of E05A02LA chip 8-line data entry in each of the 3 controls the printing of the needle-pin data signals (E05A02LA chip specific analysis of the circuit, see the back Examples of the circuit), when the machine interface circuit of the 8-bit data input line in a certain way (break) or short-circuit, with its corresponding 3-pin will not be able to pin out of print, print out the character / characters The three will appear on the white lines; 3-pin or needle in a row out of print, print out the character / characters appear on the three black lines (printing Chinese characters at this time will not be accompanied by on-line print, but when a lot of self-print Needle. Therefore, this inspection should also be noted that failure to check their interface circuit).
Second, the print head control and drive circuits to deal with examples of failure
One example: DLQ-2000K printer self-test paper when printing print character shortcomings less draw
Trouble is: DLQ-2000K self-printing paper when the printer to print out shortcomings characters few designated incomplete.
Troubleshooting: The characters from the print / draw characters fewer disadvantages of this phenomenon, caused by failure of the reasons there may be four: first, the print head to print a broken needle; Second, the print driver needle coil or open burn ; The third is to connect the first printing of the decapitation appeared on cable or plug and socket between the individual bad pins; fourth, the first print driver and control panels have a failure. First of all, with the first printing Duanzhen testing procedures to test for the first print out the needle print, the results measured, 5,13,21 needle acupuncture can not print. The following steps according to the diagnosis and rule out:
① power to close the printer, the word will be moved to the car in the middle, followed by ribbon cartridge removed and the first print from the print head in front of the board directed the first check whether there is Duanzhen printing, the results have not found Duan Zhen.
② multimeter with carefully measuring each print head of the DC coil resistance, the resistance value measured in line with the normal value.
③ check printing in the first cables to connect the pins is bad, no problem. Open the top printer from the printer to print on the right side of the first cable outlet on the board off three flat cable, pen table Multimeters the two were up in the search cable (a total of three cables, two wide print head for the cable, the most The sensor is a narrow ribbon and the motor-driven cable signal) corresponds to the two ends of the line, measuring its resistance value is zero, the measured results of the short-pin cable to connect the first group of 9 broken foot, the same model with a flat cable replacement After troubleshooting.
Failure Analysis: DLQ-2000K printer paper's print head pin short drive coil group is the first line of 9-pin, 5,13,2 l coil power of public input side, which is the root along the printer cable is directly outside the rack In a special plug socket, 3 of the cable outside and covered with a piece of metal protection. As the rack, and the most short-pin cable group coil obvious contact with the lower end of the edges and corners, just stuck the cable bending parts. Long-term friction will be the first cable 9 mill off-line, which would result in serious root on the line to short-circuit, that is, +35 V power supply side of the rack to short-circuit the whole circuit of the master printer paper work.
Second example: OKI-5330SC printer when all the bills are not a needle needle
Trouble is: OKI-5330SC paper printers start trucks to return to the character after the initial position, but in print and on-line self-test, the word car back and forth to campaign, but can not print out the needle for the first printing, print page print without trace.
Troubleshooting: boot words after the printer can return to the initial location of the vehicle on the main circuit of the printer work properly, and when printed words and from the sports car but can not pin print head to print, this phenomenon is a general prints The first control and drive circuit failure. OKI-5330SC for this printer paper, the data signal circuit pin is connected through the serial data transmission cables to the motor vehicle and character-driven on-board print head, and then driven by the boards of two 12-bit displacement drive (M2021) Parallel into the first print out the output signal pin, which would have resulted in all three print needle acupuncture can not print the fault may be: First, print head controller dedicated gate array circuit M61059 (03G) of the print needle signal compensation ODD DATACOUT printing and needle trigger signal failure ODDTRG; Second, the print head control circuit led to the failure needle Print odd signal to allow ODDEN, print driver for the first summary of current signal ODDCOMMON; Third, the print pin drive M2021 damage. To do this, follow these steps for the diagnosis and rule out:
1. Power to close the printer, feeding off the handle after the site and removed the word out motor vehicle plates. Multimeter with static measurement-driven on-board driver odd-numbered print of the needle driver M2021 (Q2) to the foot of the resistance to the positive and negative, the results of normal.
2. Unplug the printer on the shelves all the plugs to connect printers removed after the rack (to remove the four screws fixed), and then remove the main circuit board. Multimeter measured by the static control circuit board controls the print head odd / even-numbered summary of current needle-driven signal line ODD / EVEN COMMON of the transistor TRl3 / TRl2 (2SB883) of the b, c, e on a very positive way, the reverse resistance As a result, are normal.
3. Printer connected to power, were measured TRl3 the TRl2 and b, c, e, a voltage, the results of the measured values are normal voltage. Turn off the power, measured in odd-numbered pin control circuit of the comparator 2901 (0SD) to the foot of the resistance to the positive and negative, the results of normal. And then oscilloscope were then used in the 08D 4 feet and 8 feet observe the odd / even print needle trigger signal ODD / EVEN TRG, found that ODD / EVENTRG signals for a straight line.
4. Were observed M61059 (03C) chips RDN (9 feet) and the WDN (10 feet) on the RD and WR signal, the results have input signal, a preliminary diagnosis of the chip failure, a new post to replace M61059 troubleshooting.
Failure Analysis: M61059 (03C) by 8051 based on the microprocessor to control the external character dot-matrix printer, and the CMOS programmable gate array circuit. Under normal circumstances, the circuitry in the CPU (03E, 8051) under the control of the produce print needle compensation signal ODD / EVENDATACOUT printing and needle trigger signal ODD / EVENTRG, after triggering circuit and protection circuit formed by printing needle to allow the signal ODD / EVENEN, Print needle driver signal ODD / EVENDRV and print driver for the first summary of current signal ODD / EVENCOMMON. In this case is due to the failure of the circuit without damage to the internal print needle trigger signal ODD / EVENTRG output, the entire print head can print pin failure.
Three examples: AR-5400 printer to print paper when printing characters / character less serious shortcomings of the draw
Trouble is: AR-5400 printer to print paper when printing characters / character less draw very serious shortcomings, and even hard to see the print of the characters.
The process of diagnosis and rule out: print head to print more of a sewing needle can not pin printer to print characters appear / Chinese characters less serious shortcomings designated reasons, such failure is the main fault is that the first printing (including print and pin Duanzhen Print needle driver coil line, the first printing have a cable connection or disconnect plug a number of bad contacts) as well as the print head control and drive circuit failure. Duan Zhen first printing in the first test in the first print out the procedures for testing pin print, measured the results of 14,16,18,20,22, 24-pin printer can not pin. According to this failure, according to the following steps for the diagnosis and rule out:
1. Power off the printer, the word will be moved to the car in the middle, followed by ribbon cartridge removed and the first print from the print head in front of the first print-oriented on-board inspection whether Duan Zhen, the results have been found Duan Zhen.
2. Multimeter used to print the first measurement Coils of each group of DC Resistance, the measured resistance is normal.
3. Check printer cable to connect the first play of the
The first print control and drive circuits caused by the failure of the main phenomenon in three respects: First, the odd or even number needle acupuncture needles can not, the result is a character printing / severely deformed characters; Second, a number of print for a needle or pin or some individual Print print when no needle injections, the result is a print character / characters of the regular shortcomings less draw, that is, his character / characters in one or more white lines, as well as print characters / character point line together, that is, his character There are one or a few black lines, there will be serious when printing pin was to hang up. Third, we can not print all the needle acupuncture, print the page does not print writing.
First, print head fault control and drive circuits of the reasons
It should be said that various models of printer paper in the overall design is not very different, but some of the specific printer paper and the structure of the circuit is still a certain degree of difference. Therefore, the following general analysis of the first and the reasons for these failures.
1. Acupuncture needles can not print all print
All-pin printer to print bills in print when the needle was not printed, printing was mainly attributable to needle driver coil no incentive to exert high pressure so that the needle does not print the driving force rather than a needle. In addition, some bills have a specially designed pin printer data to form circuits, such as DLQ-2000K, if the first print driver HPW pulse signal failure, the needle will be unable to print to be inspired and the emergence of high-pressure needle can not print all the print needle phenomenon . Another example is the OKI-5330SC printer paper, and is to SERIALCLOCK-N signal synchronization of serial data SERIALDATA-N into the first printing of the needle parallel data signal HEADDATAl ~ 24, SERIALCLOCK-N or SERIALDA-TA-N signal failure , The needle can not print all the print needle.
2. Odd or even number needle acupuncture needle can not print
Some printers, the print head control and drive circuits designed to allow odd-numbered pin signals and even allow the signal pin. In such a design of the printer, only when the signal to allow effective needle odd, odd-numbered pin will it be possible to print out the needle; and even when the juice to allow an effective signal, the needle can even print out the needle. If the odd or even number needle acupuncture needle can not print, testing should be odd or even-numbered pin pin signals whether or not to allow normal. Such as OKI-5330SC, the print head control and drive circuits designed to allow odd-numbered pin signal ODD-EN needle and even allow the signal EVEN-EN.
3. Print part of the individual or needle acupuncture can not print
When the needle to form the data circuit (or circuits dedicated gate array) and circuit Driven pin print individual devices in a part of the damage, it will cause a partial or no acupuncture needle printing individual print. In some printer paper, the incentive is a sub-four-way high-pressure needle to the print driver provided by the coil (such as the AR-5400, AR-6400 paper in the printer to print can be divided into four needle coil incentive to exert high pressure, and the Lexmark 2391Plus paper in the printer is Fensan Lu-pin printer driver for the module to provide the high-pressure). In this form of circuit, which damaged all the way from those it provides high-voltage pin (6 or 8) will not be able to print out the needle. In general, when the printer paper in the print process, the rules have less to 6 or 8-pin failure of this phenomenon, it is possible that this is three or four in a road damage. Therefore, in this type of examination fault circuit should be based on the specific printer paper's print pin driver circuit analysis and testing, the last to find out the damage to the device and be replaced. In addition to print output in the first cable outlet will also be bad for the first printing of individual print needle acupuncture can not print.
Used as a chip in E05A02LA pin data to form the circuit DLQ-2000K printer paper, as a result of E05A02LA chip 8-line data entry in each of the 3 controls the printing of the needle-pin data signals (E05A02LA chip specific analysis of the circuit, see the back Examples of the circuit), when the machine interface circuit of the 8-bit data input line in a certain way (break) or short-circuit, with its corresponding 3-pin will not be able to pin out of print, print out the character / characters The three will appear on the white lines; 3-pin or needle in a row out of print, print out the character / characters appear on the three black lines (printing Chinese characters at this time will not be accompanied by on-line print, but when a lot of self-print Needle. Therefore, this inspection should also be noted that failure to check their interface circuit).
Second, the print head control and drive circuits to deal with examples of failure
One example: DLQ-2000K printer self-test paper when printing print character shortcomings less draw
Trouble is: DLQ-2000K self-printing paper when the printer to print out shortcomings characters few designated incomplete.
Troubleshooting: The characters from the print / draw characters fewer disadvantages of this phenomenon, caused by failure of the reasons there may be four: first, the print head to print a broken needle; Second, the print driver needle coil or open burn ; The third is to connect the first printing of the decapitation appeared on cable or plug and socket between the individual bad pins; fourth, the first print driver and control panels have a failure. First of all, with the first printing Duanzhen testing procedures to test for the first print out the needle print, the results measured, 5,13,21 needle acupuncture can not print. The following steps according to the diagnosis and rule out:
① power to close the printer, the word will be moved to the car in the middle, followed by ribbon cartridge removed and the first print from the print head in front of the board directed the first check whether there is Duanzhen printing, the results have not found Duan Zhen.
② multimeter with carefully measuring each print head of the DC coil resistance, the resistance value measured in line with the normal value.
③ check printing in the first cables to connect the pins is bad, no problem. Open the top printer from the printer to print on the right side of the first cable outlet on the board off three flat cable, pen table Multimeters the two were up in the search cable (a total of three cables, two wide print head for the cable, the most The sensor is a narrow ribbon and the motor-driven cable signal) corresponds to the two ends of the line, measuring its resistance value is zero, the measured results of the short-pin cable to connect the first group of 9 broken foot, the same model with a flat cable replacement After troubleshooting.
Failure Analysis: DLQ-2000K printer paper's print head pin short drive coil group is the first line of 9-pin, 5,13,2 l coil power of public input side, which is the root along the printer cable is directly outside the rack In a special plug socket, 3 of the cable outside and covered with a piece of metal protection. As the rack, and the most short-pin cable group coil obvious contact with the lower end of the edges and corners, just stuck the cable bending parts. Long-term friction will be the first cable 9 mill off-line, which would result in serious root on the line to short-circuit, that is, +35 V power supply side of the rack to short-circuit the whole circuit of the master printer paper work.
Second example: OKI-5330SC printer when all the bills are not a needle needle
Trouble is: OKI-5330SC paper printers start trucks to return to the character after the initial position, but in print and on-line self-test, the word car back and forth to campaign, but can not print out the needle for the first printing, print page print without trace.
Troubleshooting: boot words after the printer can return to the initial location of the vehicle on the main circuit of the printer work properly, and when printed words and from the sports car but can not pin print head to print, this phenomenon is a general prints The first control and drive circuit failure. OKI-5330SC for this printer paper, the data signal circuit pin is connected through the serial data transmission cables to the motor vehicle and character-driven on-board print head, and then driven by the boards of two 12-bit displacement drive (M2021) Parallel into the first print out the output signal pin, which would have resulted in all three print needle acupuncture can not print the fault may be: First, print head controller dedicated gate array circuit M61059 (03G) of the print needle signal compensation ODD DATACOUT printing and needle trigger signal failure ODDTRG; Second, the print head control circuit led to the failure needle Print odd signal to allow ODDEN, print driver for the first summary of current signal ODDCOMMON; Third, the print pin drive M2021 damage. To do this, follow these steps for the diagnosis and rule out:
1. Power to close the printer, feeding off the handle after the site and removed the word out motor vehicle plates. Multimeter with static measurement-driven on-board driver odd-numbered print of the needle driver M2021 (Q2) to the foot of the resistance to the positive and negative, the results of normal.
2. Unplug the printer on the shelves all the plugs to connect printers removed after the rack (to remove the four screws fixed), and then remove the main circuit board. Multimeter measured by the static control circuit board controls the print head odd / even-numbered summary of current needle-driven signal line ODD / EVEN COMMON of the transistor TRl3 / TRl2 (2SB883) of the b, c, e on a very positive way, the reverse resistance As a result, are normal.
3. Printer connected to power, were measured TRl3 the TRl2 and b, c, e, a voltage, the results of the measured values are normal voltage. Turn off the power, measured in odd-numbered pin control circuit of the comparator 2901 (0SD) to the foot of the resistance to the positive and negative, the results of normal. And then oscilloscope were then used in the 08D 4 feet and 8 feet observe the odd / even print needle trigger signal ODD / EVEN TRG, found that ODD / EVENTRG signals for a straight line.
4. Were observed M61059 (03C) chips RDN (9 feet) and the WDN (10 feet) on the RD and WR signal, the results have input signal, a preliminary diagnosis of the chip failure, a new post to replace M61059 troubleshooting.
Failure Analysis: M61059 (03C) by 8051 based on the microprocessor to control the external character dot-matrix printer, and the CMOS programmable gate array circuit. Under normal circumstances, the circuitry in the CPU (03E, 8051) under the control of the produce print needle compensation signal ODD / EVENDATACOUT printing and needle trigger signal ODD / EVENTRG, after triggering circuit and protection circuit formed by printing needle to allow the signal ODD / EVENEN, Print needle driver signal ODD / EVENDRV and print driver for the first summary of current signal ODD / EVENCOMMON. In this case is due to the failure of the circuit without damage to the internal print needle trigger signal ODD / EVENTRG output, the entire print head can print pin failure.
