When printing on the 1st side is done and the leading edge of paper reaches the delivery assembly jam detection sensor (PS4), the reversing flapper solenoid

goes on. When the delivery assembly jam sensor (PS46) goes on and the paper arrives at a specific point, the reversal motor (M14) starts to rotate to move

the paper to the duplexing reversing assembly. When the paper reaches the reversal sensor 2 (PS38) and then a specific point, the reversal motor (M14)

stops to rotate so that the paper is kept on hold at the reversing assembly.

Thereafter, when the reversal motor (M14) starts to rotate in reverse, the paper in the reversing assembly is moved toward the duplexing wait point by the

work of the duplexing feed left/right roller, which is operated by the drive from the duplexing feed left/right motor (M19, M18). When the paper reaches

the duplexing repickup point (before 40mm of the curling roller), the parer stops and the horizontal registration operation is executed.

The paper is then moved to the duplexing wait point as soon as the duplexing feed left/right motor (M19, M18) starts to rotate again.

MEMO:

The paper is not arched. (both case thick paper mode and plain paper mode)
