Description

Technical Field

[0001] The utility model relates to the technical field of laser printing, and more specifically to a laser printing cartridge. Background Art

[0002] The toner cartridge of a laser printer is one of the key components. It contains toner and a photosensitive element, which is used to send the image from the computer to the printer and form it on the paper. The working principle of the toner cartridge is to use the laser printer to create an electrostatic image on the surface of the toner cartridge through a laser beam, then adhere the toner to these electrostatic images, and finally transfer the toner to the paper through heat and pressure to form a printed image.

[0003] The cleaning blade of the photosensitive drum plays a very important role. It is responsible for removing the residual toner and other impurities on the surface of the photosensitive drum. If the cleaning blade of the photosensitive drum is severely worn, it may lead to reduced print quality, toner residue, and even damage to the photosensitive drum.

[0004] The cleaning scraper of the photosensitive drum is fixed to the printer with bolts. During the disassembly and assembly process, if the bolts are not properly kept or fall into the printer, the corresponding bolts may not be found during the subsequent assembly, delaying the maintenance time. Due to the small internal space of the toner cartridge, it is inconvenient to use auxiliary tools to disassemble and assemble the bolts. The bolts may rust or deform due to long-term fixation, making disassembly difficult. Utility Model Content
