How to regenerate toner cartridges for laser printers

Abstract

The invention discloses a toner cartridge regeneration method for a laser printer. The method comprises the following steps: (1) separating a first end cover, a bearing, a toner cartridge frame and other parts from one another; (2) cleaning the obtained separated parts; (3) filling new powder into a toner cartridge, and closing the toner cartridge; and (4) reversely assembling the parts obtained in the previous steps, wherein the bearing is fixed at the original position of the first end cover in advance before the first end cover, the bearing and the toner cartridge frame are separated. The first end cover and the toner cartridge frame are separated by the original binding part between the first end cover and the toner cartridge frame, and then the first end cover is cut apart. The regeneration method is simple and feasible; and the regenerated toner cartridge is high in quality, and powder leakage is avoided.

Description

technical field [0001] The invention relates to a regeneration method of a toner cartridge for a laser printer. The toner cartridge involved in the regeneration method is a toner cartridge including a photosensitive drum, a developing roller, a powder discharge knife, a powder feeding frame, a toner bin and a waste toner collection bin. It lays the toner contained in the toner chamber on the electrostatic latent image area on the surface of the photosensitive drum according to the preset layout through the developing roller, so that the electrostatic latent image is converted into a visual image displayed by a developer such as toner. Background technique [0002] Image forming devices generally include various models such as copiers, laser printers, facsimile machines, ribbon printers, and LED printers. [0003] As a type of laser image forming device, the main functional blocks of a laser printer include: a laser scanning unit, a photoelectric conversion unit, a charging ...
