The entire laser printing process is carried out by the action of "charging". First, the photosensitive drum is filled with negative or positive charges. The raster bitmap image data in the printing controller is converted into the laser beam information of the laser scanner, and the photosensitive drum is directed through the reflecting prism. "Exposure", the surface of the photosensitive drum forms image information that is exactly the same as the printed image represented by a positive charge, and then adsorbs […]
