Toner chips

Toner cartridge chip allows users to clearly understand the use of toner cartridges and toner cartridges, that white is the drum "guardian." It is based on the use of toner cartridges to determine the status of toner cartridges. The toner chip is the main part of the laser printer. The cartridge core is made of some photosensitive material and contains selenium. The basic principle of the laser printer is that the characters and graphics are encoded after the laser shines on the drum core above the surface, by the laser light will produce part of the photoelectric effect, resulting in static electricity, the toner to attract out. The drum cartridge is automatically disabled after the alarm is prompted, and the print demand can not be achieved even if the cartridge is refilled again. In theory, the cartridge chip can be relatively objective response to the life of the cartridge, but this monitoring is not accurate, and the alarm after the cartridge is not really can not be used, the drum chip does not allow the printer to use. So in order to avoid the high amount of money for the drum, you can clear the chip on the cartridge and fill the toner, so that the cartridge can be used repeatedly to reduce the cost of late inputs. Only when the drum itself is damaged (usually the surface film scratch), the cartridge was really the get out of class.
