Driving Power Transmission to Drum and Transfer Roller
The driving power generated by the motor assembly is transmitted from gear 4 of the
main drive assembly to the drum of the toner cartridge.
The driving power is then transmitted from the drum to the Transfer Roller. The
connection of the shaft of gear 4 (that transmits the driving power) with the drum is
controlled by the cover open cam driven by opening and closing the top cover. The driving
power is not transmitted to the toner cartridge unless the top cover is closed.
