Cleaning Mechanism

[A]
[B]
[C]
The transfer-belt cleaning unit is located on top of the transfer belt [F]. The four
basic components of the transfer belt cleaning unit and their functions are:
1. The cleaning brush [B] - This component removes the excess toner [C] from
the transfer belt.
2. The cleaning roller [A] - This component removes the toner from the cleaning
brush. The high voltage unit (HVU) provides a cleaning bias to the cleaning
roller. The left end of the cleaning roller is attached to FCBV terminal on the
HVU.
3. The cleaning blade [D] - This component removes the toner from the cleaning
roller.
4. The toner removed by the cleaning blade goes into the waste toner path. The
waste toner feeder [E] moves the toner to the right end of the waste toner path.
At this time, the toner goes into the waste-toner collection unit.

Drive

The main motor drives the right side gear of the cleaning roller via idle gears. The
left side gear of the cleaning roller transmits this drive power to the cleaning brush
and the waste toner feeder.
