[0002] The printer selenium drum and the clean scraper are important components in the printer, each of which plays a different role. The selenium drum is one of the core components in the printer. Depending on the different photosensitive materials, it can be basically divided into an OPC drum (organic photoconductive material), a selenium drum (Se), and a ceramic drum (a-si ceramic). The selenium drum is responsible for receiving the irradiation of a laser beam during the printing process, converting image or text information into an electrical signal, and then realizing printing through toner adsorption. The clean scraper is a component of the printer selenium drum, mainly used for cleaning the surface of the selenium drum to remove residual toner and impurities, ensuring the printing quality and normal operation of the selenium drum. The clean scraper is usually made of wear-resistant material and has a long service life.

[0003] However, the existing clean scraper attached to the selenium drum can clean toner, but the scraped toner may remain in the printer shell, and some toner may adhere to the scraper, which makes it easy for the scraped toner to re-adsorb onto the selenium drum, resulting in incomplete cleaning. Therefore, there is a need for a clean scraper for printer selenium drum to solve the problems existing in the prior art. SUMMARY
