Embodiment Construction
[0018] Introducing the regeneration method of the present invention, the laser printer developing cartridge that is recycled using the regeneration method is firstly described, so that those skilled in the art can better understand the technical essence of the regeneration method.
[0019] see figure 1 , 2 , 3, show a conventional developing cartridge 1 for a laser printer. In the figure, the state where the developer cartridge 1 is installed in the laser printer is used as a frame of reference for describing it. In this mounted state, the constituent member of the developing cartridge 1, that is, the developing roller 105, has its axis parallel to the horizontal plane. Or in other words, the developing cartridge 1 is described with a posture in which the central axis of the developing roller 105 is parallel to the horizontal plane. The developing cartridge 1 is a semi-cylindrical box with a generally elongated appearance, and its cross section in the longitudinal direction...

The invention is a regeneration method of a developing box of a laser printer. The related developing box comprises a powder chamber and a developing roller. The developing roller is arranged at a powder outlet. A powder outlet knife and a sealing strip are respectively arranged in a first gap and a second gap between the inner wall of the developing roller and the powder outlet. The powder outlet knife seals the first gap, and the sealing strip seals the second gap. The powder chamber is provided with a feeding port. The regeneration method comprises the steps of obtaining a clean powder chamber and a clean developing roller, feeding the carbon powder into the powder chamber, sealing the feeding port by adopting an original or new cover after feeding, wherein, the clean power chamber andthe clean developing roller are obtained according to the following steps: first, the sealing cover is removed, and then the inner cavity of the powder chamber is sucked by airflow from the feeding port. The regeneration method can rapidly process the developing box, the carbon powder in which is used up.
Description
technical field [0001] The invention relates to a method for regenerating a developing cartridge of a laser printer. The developing cartridge is composed of a powder bin for accommodating a developer such as carbon powder and a developing roller for transferring the carbon powder and arranging it on an electrostatic latent image generated by a photosensitive drum of a laser printer. composition, and the toner in its toner bin has been exhausted. Background technique [0002] An electrophotographic imaging device, such as a laser printer, irradiates a photosensitive drum with a predetermined uniform potential by laser scanning to form an electrostatic latent image on its surface. The electrostatic latent image is developed with a predetermined toner, and then the developed image is transferred to the paper, and then the transferred image is fixed to become a visible image that can be observed by the naked eye, thereby realizing the image-signal - Transformation between image...
