Technical Field
The utility model relates to a printer consumptive material field especially relates to a no waste powder selenium drum.
Background
At present, most of toner cartridges for laser printing adopt an integrated structure comprising a powder bin and a waste powder bin, the toner cartridges with the integrated structure are not easy to disassemble, and the whole toner cartridge is discarded after carbon powder in the toner cartridge is used up; although the powder is charged after the first use, the powder is not popular because of the complicated operation and the diffusion of dust. The powder bin and the waste powder bin of the integrated-structure selenium drum containing the powder bin and the waste powder bin are respectively closed and are not directly communicated with each other. The powder bin is used for storing new carbon powder, and the waste powder bin is used for storing waste powder collected from the surface of the photosensitive drum by the cleaning scraper in the printing process.
Along with the existing paper quality is higher and higher, paper scraps contained in waste powder generated by the existing toner cartridge are few, and the toner cartridge can be completely reused, but the existing toner cartridge capable of filling powder needs to take out the waste powder for reuse, the operation process is very complicated, and although some toner cartridges capable of recycling the waste powder appear on the market, the toner cartridges are always provided with a supply mechanism to convey the waste powder to a powder bin, so that the toner cartridge is more complex in structure and is easy to damage.
Therefore, a waste powder-free selenium drum is needed to solve the problem that the waste powder of the existing selenium drum cannot be fully utilized.
