Description

Technical Field

[0001] The utility model relates to the technical field of selenium drums, in particular to a selenium drum with a selenium drum scraper. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. Toner cartridges are an important component of laser printers. Most of the imaging components are concentrated inside the toner cartridges. The toner cartridge determines the quality of printing. Toner cartridge scrapers are one of the accessories of toner cartridges. The toner cartridge scrapers can be used to scrape off the remaining toner on the surface of the drum core.

[0003] CN202121919369.4 introduces a toner cartridge with a toner cartridge scraper. The first spring allows the first scraper to be in close contact with the outer surface of the drum core, so that the residual toner on the drum core surface can be cleaned with good cleaning effect. At the same time, when the printer is working, the motor is started, and the motor drives the second scrapers on the left and right sides to move relative to or apart, and then the waste will fall into the collection tube through the drop tube, avoiding the need for personnel to open the printer and remove the toner cartridge for cleaning, thereby improving the cleaning efficiency.
