Image-formation system
Electrophotographic process
The electrophotographic process forms an image on the paper. Following are the major components
used in the process:
Print cartridges
Intermediate transfer belt (ITB)
Secondary transfer roller
Fuser
Laser scanner
The DC controller uses the laser scanner and HVPS to form the toner image on the photosensitive drum.
The image is transferred to the print media and then fused onto the paper.
