A selenium drum capable of cleaning a grid mesh manually

Abstract

Disclosed is a selenium drum capable of cleaning a grid mesh manually, which relates to the field of laser printers and comprises a lower cover, an upper cover, a transfer roller, a photosensitive drum, a grid mesh, a corona wire, a cleaning slider and a cleaning rod. The rear end of the lower cover is provided with a cleaning rod groove, and the cleaning rod can be fixedly stored in the cleaningrod groove; the cleaning rod is of a Y-shaped structure, the left end of the clean rod is provided with a handle, the right end is provided with two pieces of parallel glue plates, the peripheries ofthe two glue plates are each covered with a layer of soft hairbrush, the positions of left and right sides of the upper cover directly facing the grid mesh are each provided with an opening, when theselenium drum needs cleaning, the cleaning rod stored in the cleaning rod clamping position at the rear end of the lower cover is taken out, the hairbrush at the upper end of the cleaning rod is aligned with the side face opening of the upper cover, the grid mesh is clamped with the glue plates to be brushed back and force, after cleaning is completed, the cleaning rod is utilized to stretch intothe opening in the other side in the same way, and the grid mesh is cleaned from the other side. After use, the cleaning rod is put back into the cleaning rod clamping position, so that carbon powderon upper and lower sides of the grid mesh can be cleaned at the same time, and excessive accumulation of carbon powder is prevented from affecting the use effect of the selenium drum.

Description

technical field [0001] The invention relates to a toner cartridge capable of manually cleaning grids, and relates to the field of laser printers, in particular to a toner cartridge. Background technique [0002] Toner cartridges currently mainly have two charging methods: charging roller charging and corona wire charging. Toner cartridges charged with corona wire often encounter corona wire and the carbon flying out from the front and back sides of the grid used in conjunction with it during the printing process. Toner sticks on the toner, causing printing abnormality or machine prompt error, but currently the toner cartridge only provides a cleaning device for cleaning the corona wire, and cannot clean the grid, so more and more toner is accumulated on the grid during use, and it will Affect print quality, reduce print life and customer experience. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned prior art, the present invention provid...
