Description

Technical Field

[0001] The utility model relates to the field of selenium cartridges, in particular to a selenium cartridge device which is convenient for filling the selenium cartridge with powder. Background Art

[0002] A toner cartridge is a consumable part of a printer, usually used in a laser printer or copier. The toner cartridge contains a photosensitive drum (also called a photosensitive drum), which is used to receive the image or text information transmitted by the printer and transfer it to the printing paper.

[0003] Application number: CN202320566465.8, discloses a toner cartridge with a toner cartridge scraper, which facilitates the connection between the rear shell and the toner cartridge body by the clamping of the clamping plate and the clamping slot, and also facilitates the disassembly of the rear shell to expose the toner cartridge scraper, and can be removed by moving the slide plate upward, which is convenient for replacing the toner cartridge scraper, and also convenient for pouring out and cleaning the waste toner powder inside the rear shell, so as to continue to use the remaining toner powder inside the toner cartridge; during installation, the toner cartridge scraper can be fixed by squeezing the horizontal plate and the fixed plate against each other, thereby improving the stability of the toner cartridge scraper;

[0004] When filling the toner cartridge device with toner, the toner cartridge device needs to be taken out of the printer. At this time, the photosensitive drum will be exposed to light and is difficult to shield, which may easily cause damage to the photosensitive drum.
