Image-formation system Electrophotographic process The electrophotographic process forms an image on the paper. Following are the major components used in the process: ● Print cartridge ● Transfer roller ● Fuser ● Laser/scanner ● High-voltage power supply The DC controller uses the laser/scanner and HVPS to form the toner image on the photosensitive drum. The image is transferred to the paper and then fused onto the paper.
