20. REVERSE/PAPER EXIT SECTION
20.3.2

Reverse/paper exit timing control

• In face down paper exit, paper conveyed from the fusing section to the reverse decurler roller passing under
the reverse gate.
• The reverse decurler roller conveys the paper to the small size roller by the normal rotation of the decurler
motor (M55).
• The small size roller and the reverse roller /Lw convey the paper to the ADU reverse section by the reverse
paper exit motor (M33).
• When the decurler sensor (PS62) detects the rear end of paper and turns off [2], the M55 and M33 switch
to reverse rotation.
• The rollers rotate in reverse and convey the paper in reverse direction, but due to the guide on the convey-
ance path, the paper is conveyed to the paper exit roller, not to the reverse gate side.
• By means of the above operations, paper is exited with its upside down.
• When the paper exit sensor (PS13) detects the rear end of the paper and turns off [3], the M55 and M33
starts the normal rotation again and the next paper is reversed/exited.
