Drive Mechanism

2.
The cleaning unit is driven by the drum flange gear. The force is trans-
mitted to each part as follows:
Drum Flange Gear --> Cleaning Unit Drive Gear (Dual Gear) -->
--> Cleaning Brush Gear --> Toner Collection Coil Gear (Dual Gear) -->
--> Bias Roller Gear
A groove cam inside the cleaning unit drive gear moves the cleaning blade
from side to side during the copy cycle.
