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 staple shift motor (FSM) to return the sta-
pler unit to the home position. The stapler unit starts moving toward
the front of the stapler frame. It stops when the staple shift home
position sensor (FSTHPD) on the slide PCB located under the sta-
pler unit. Next, the staple shift motor (FSM) 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.

B. Stapling Operation
When stacking and alignment of paper on the processing tray are
complete, the finisher controller PCB drives the paddle motor
(FPM) 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.
The finisher control PCB shifts the stapler according to the speci-
fied staple position to perform stapling. (Only for B5-R, 1-position
bottom stapling is made at the rear side of 2-posiiton stapling.)
When the stapler shifts toward you, the process tray stopper is put
down to the lower side.
