6.4.2. Printing Process Operation
The Printing Process Operation consists of Process Unit and Toner Bottle with Toner supplied. Toner is
supplied to the Process Unit using gravity.
The Process Unit includes the Toner Paddle and Mag Roller (1048) that supplies Toner to the OPC Drum
(1001).
The Cleaning Blade is attached to the OPC Unit. The Cleaning Blade scrapes the OPC Drum surface to
remove the excess toner on the surface of the OPC Drum into the Toner Waste Chamber. The removed
toner is moved into the Toner Waste Container by means of Toner Waste Paddle and Toner Waste Drive.
Charge
In the dark, the Bias Charge Roller (1036) applies a high, uniform negative charge to the surface of the
OPC Drum. The surface potential is approximately -560 VDC and remains because the drum has a high
electric resistance in the dark.
