The drive force from the main motor is transmitted to the cleaning unit drive
gear via the timing belt [A] and the cleaning unit coupling [B]. The cleaning
unit drive gear then transmits the force to the front side through the cleaning
brush [C] and flick roller [D]. The force at the front side is used for the blade
cam gear [E] and toner collection coil gear [F].
There is a one-way clutch in the transport unit drive gear [G] to prevent the
drive parts in the cleaning unit from receiving the reverse rotation force.
