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.
