4.2 Drive System
The PFU has no motor for transporting paper. Paper is transported by transmitting the driving force of the
main motor of the copier to the gear. The driving force from the copier side is transmitted to the PFU pickup
clutch through the gears (four pcs.). Installing the cassette causes the pickup roller to lower. The PFU
pickup clutch turns ON and OFF the gear driving force from the copier. When picking up the paper, it turns
ON to transmit the driving force to the feed roller and pickup roller through the shaft and belt. When the
pickup roller turns, the paper is picked up from the cassette and brought to the transport path.
The tray-up operation is performed by the PFU tray-up motor. Consisting of the DC motor, worm gear, gear,
coupling, etc., the PFU tray-up motor is housed within a case as a unit. When the cassette is installed, the
coupling of this motor unites with the coupling of the cassette to transmit the motor rotation to the arm
under the cassette and lift the cassette tray.
