Processing Tray Paper Stacking Operation

1) When the paper fed from the feed unit reaches the feed path paper sensor (S108), the
processing tray paper retainer motor (M118) is driven to lower the paper retainer, thus
pressing down the sheets in the processing tray (if they exists in the processing tray)

2) When the leading edge of paper reaches the stack delivery roller, the swing guide motor
(M110) is driven to lower the swing guide, feeding the paper between the stack delivery
rollers. If sheets are stacked on the processing tray, the lower stack delivery roller does not
rotate to prevent the stacked sheets from being delivered.

4) The stack delivery roller rotates in the reverse direction to feed paper to the processing
tray unit. At this time, the paper return guide rmotor (M112) is driven to lower the paper, thus
pressing down the paper fed to the processing tray unit. The paper return guide roller motor
(M121) is driven to rotate the paper return guide roller, feeding the paper until it stops against
the processing stopper.
