Avoid frequent boot printer, copier main switch is turned ON, after a few minutes to run before being able to enter the ready state. During the pre-operation, the fixing heater preheats, the exposure lamp, the discharge lamp and other irradiation drums. If you temporarily stop copying, press the energy saver button without turning off the printer or copier main switch. Press the energy saver key again The copier can immediately go to the ready state. This will be pre-run on the drum life to minimize the impact.

Avoid continuous high temperature and high humidity in the environment to print cartridges made of semiconductor materials, the most appropriate operating temperature of about 35 ℃. The photoconductivity of the toner cartridge decreases with increasing temperature. Long-term use of drums at high temperatures can exacerbate the aging of drums, and the process is irreversible. When the ambient humidity is too high, the water molecules in the air are easily ionized, and the surface potential of the cartridge is high. Serious copies will appear on the multiple images without the white spot, indicating that the cartridge has been partially breakdown.

Therefore, in high temperature rainy season copier continuous working time should not exceed half an hour. 6, the choice of high-quality paper paper toner image transfer contact with the drum and produce the same friction. The use of uniform and delicate texture of paper can copy paper on the drum to minimize the wear and tear, delay the aging process of the cartridge, to extend the life of the cf217a compatible is beneficial. If you use wrinkles, missing or too thick cut, too hard and other paper, will affect the print quality and wear photosensitive drum.

Grinding can remove the aging layer on the drum surface and restore the photoconductivity of the drum. According to the provisions of the toner cartridge should be polished every 20,000 sheets, but usually 40,000 sheets after the aging layer will lead to a hard copy of the end of the production of ash. So the first grinding drum should be carried out after 40,000 sheets. Grinding the drum is best to use a special abrasive. However, the use of cotton wool dipped in chromium oxide (a chemical reagent) or toothpaste grinding, cotton wool dipped in anhydrous alcohol to clean the surface of the drum no less effective than the special abrasive. Should pay attention to grinding force to light and uniform, after all, drum surface photosensitive alloy layer thickness of only 30 microns. After grinding should be used immediately.
