Laser printer maintenance manual

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.

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.
