Background
A toner cartridge, also known as a photosensitive drum, is generally composed of a base substrate made of aluminum, and a photosensitive material coated on the base substrate. In laser printers, more than 70% of the image forming components are concentrated in the cartridge, and the quality of printing is actually determined to a large extent by the cartridge. The cartridge determines not only the quality of the print, but also the amount of money the user spends during use.
The carbon powder of the toner cartridge is a kind of charged fine resin particles, the polarity of the carbon powder charge is opposite to the charge polarity on the toner cartridge surface, when the charged toner cartridge surface passes through the inking roller, the charged part adsorbs the toner particles, and the latent image is changed into a real image. When the toner cartridge rotates in operation, the printing system conveys printing paper, the printing paper is charged with electric charges which have the same polarity as the surface of the toner cartridge but are much stronger, then the paper passes through the toner cartridge with toner, the toner on the surface of the toner cartridge is attracted onto the printing paper, and an image is formed on the surface of the paper. At this time, the toner and the printing paper are bonded together only by the attraction of electric charges, and the toner is melted by heating at a high temperature before the printing paper is sent out of the printer and is solidified on the surface of the paper in the cooling process. After the toner is attached to the printing paper, the surface of the toner cartridge continues to rotate, past a cleaner, to remove the remaining toner for the next printing cycle.
The existing selenium drum transmission structure is complex and is easy to generate faults.
