Paper Exit Roller Drive Coupling
When the Duplex Unit is mounted, the gear assy of the Fusing Unit is raised by the leading
edge of the Duplex Unit lever, thereby disconnecting drive from the machine (Fusing Roller).
The Paper Exit Roller is driven by the Duplex Reverse Motor.
Switchback Motor Control
Rotation of the Duplex Reverse Motor (M9 DU) is controlled by the signal output from the
Duplex Board (PWB-A DU).
Transport and Duplex Paper Take-Up Mechanism
Transport and Duplex Paper Take-Up Operation
