Reversing and duplexer pickup
The duplexer has two stepping motors: the reversing motor (M701) and the duplex-feed motor
(M702). The duplexer driver controls forward and reverse motor rotations.
The duplexer solenoid controls the face-up output tray diverter, which feeds paper to the duplexer.
NOTE The duplexer cannot be used if the face-up tray is open.
When the trailing edge of the media passes the reverse sensor (PS703), the reversing motor
changes direction. The oblique roller and feed roller then move the media so that its edge makes
contact with the left panel to correct skew.
