Step 5: Cleaning (Drum/Charge roll)
The Cleaning Blade removes any toner that remains on the drum after the transfer process. The toner that the
Cleaning Blade removes is collected inside the sealed PC Cartridge and reused. This is performed after each
plane of color has been transferred to the transfer belt from the photoconductors.
An erase lamp also electrically cleans the drum. The drum is discharged by exposure of light from the erase
lamp.
Step 6: 2nd Transfer
As the paper travels and makes contact with the transfer belt, the 2nd transfer roll assembly is charged with
negative DC voltage from the HVPS. This causes the toner image to transfer from the transfer belt to the surface
