Stack assist control

The stack assist plate is a paper pressure plate that is used to increase the speed to put paper in the stacker for
an increased productivity.
The stack assist plate [1] is driven by the stack assist motor (M24). When being conveyed to the stacker section,
each sheet of paper is pressed at the position near the rear end of the paper [2] to be stacked at a speed faster
than a free fall.
The stack assist plate is driven by 65° from the home position in the staple mode and by 80° in the shift and
straight mode. The home position is detected by the stack assist home sensor (PS32) [3].

Rear stopper control

The rear stopper is a paper rear stopper when paper is exited in the non-staple (straight/sort) mode. This short-
ens the conveyance distance to the main tray for an improved productivity.
The rear stopper is driven and released by the rear stopper motor (M26) in the staple mode.
The set state in the non-staple mode (the position at which paper is stopped by the rear stopper) is the home
position of the rear stopper and this is detected by the rear stopper home sensor (PS35).
