2.3.4 Stack Delivery Operation
Stack delivery takes place when 10 sheets of large-size paper or 30 sheets of small-size
paper (A5- and STMT-sizes: 10 sheets) have been stacked on the processing tray with them
offset in either direction.
offset in either direction.
The paddle motor rotates and the swing guide descends to hold the paper stack between
the upper and lower stack delivery rollers. The delivery motor rotates in the forward direc-
tion to rotate the delivery rollers, feeding the paper stack in the delivery direction. The deliv-
ery belt home position sensor is turned OFF. The delivery motor is driven a specified num-
ber of pulses, causing the swing guide to ascend. Next, the paper delivery motor is driven.
Next, the delivery motor is driven to deliver the paper stack with the nails of the delivery

3. Stapling Operation
3.1 Outline
Staple operation is performed to staple a specified sheets of paper using a stapler unit.
The stapling position depends on the staple mode and paper size.

The stapling position depends on the staple mode and paper size.
When the machine starts immediately after power-on, the finisher controller PCB drives
the slide motor (M8) to return the stapler unit to the home position. The stapler unit starts
moving toward the front of the stapler frame. It stops when the slide home position sensor

CHAPTER 2 OUTLINE OF OPERATION
3.2 Stapling Operation
When stacking and alignment of paper on the processing tray are complete, the finisher
controller PCB drives the paddle motor (M2) in the reverse direction and lowers the swing
guide. When the swing guide descends, the paper stack is sandwiched between the upper
and lower stack delivery rollers.

and lower stack delivery rollers.
The finisher controller PCB moves the stapler for stapling according to the specified sta-
pling position (when rear 1-point stapling is specified, the stapler does not move but it
staples at the standby position). As the stapler moves forward, the processing tray stopper is
folded forward.
