Image-formation process
The image-formation system creates the printed image on the paper. The system consists of the following
components:
●
Toner cartridge
●
Transfer roller
●
Fuser
●
Laser/scanner
●
High-voltage power supply
The DC Controller controls the internal components of the image formation system (according to commands
received from the formatter) to form the toner image on the photosensitive drum surface. The toner image is
then transferred to the print media and fused.
Figure 1-9 Image-formation system
The fuser motor (M1) drives the following image formation components:
●
Photosensitive drum
●
Developing roller
●
Primary charging roller (follows the photosensitive drum)
●
Transfer roller (follows the photosensitive drum)
●
Pressure roller
●
Fuser lm (follows the pressure roller)
NOTE: The primary charging roller and developer roller are located in the toner cartridge.
