1.12.3 Operation
(1) Paper transport control
1. Paper transport
• The fusing motor and ADU reverse rotation clutch provides drive for paper transport onto the duplex section.
• The duplex transport clutch controls the main motor to rotate, to drive the ADU transport roller.
• The ADU transport roller transports paper from the duplex section to re-feeding position.
• The duplex transport sensor is located at the re-feeding position in the duplex section, serving to control the timing at which paper is
moved and detect paper misfeed or paper left in the duplex section.
