To reduce load on the main motor, the development unit uses a separate
drive motor [A]. The development drive pulley turns the development drive
belt [B] which turns the development drive gear [C]. The development drive
gear turns the development roller gear [D] and the paddle roller gear [E]. The
auger gear [F] is engaged with the paddle roller gear. Thus, the development
roller, paddle roller, and auger all turn when the development drive motor is
on.
The toner agitator gear [H] is also turned by an idle gear [G], which is
engaged with the auger gear. However the toner agitator does not turn unless
the toner supply clutch [I] is engaged. It engages when the toner supply
solenoid turns on.
