(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.
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 direction to rotate the delivery
rollers, feeding the paper stack in the delivery direction. The delivery belt
home position sensor is turned OFF. The delivery motor is driven a
specified number 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 belt that rotates in
sync with the stack delivery rollers.

3. Stapling Operation
A.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.
When the machine starts immediately after power-on, the finisher
controller PCB drives the slide motor (FSM) 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 (SHPS) on
the slide PCB located under the stapler unit. Next, the slide motor is
driven a specified number of pulses. The stapler unit moves to rear
standby position at the back of the machine, entering the standby state.
