D.Stapler Unit
The staple/fold motor (FFSM) is used to perform stapling operation. This
motor rotates the cam one turn for stapling. The home position of this
cam is detected by the staple home position sensor (STHPS).
The staple/fold motor is rotated in the forward or reverse direction under
the control of the macro computer (IC13) on the finisher controller PCB.
When the staple home position sensor is OFF, the finisher controller PCB
rotates the staple/fold motor in the forward direction until the sensor turns
ON, allowing the stapler to return to the original position.
The staple empty sensor (SPS) is used to detect presence/absence of a
staple cartridge in the machine and presence/absence of staples in the
cartridge.
The stale top position sensor (SS) is used to determine whether staples
are pushed up to the top of the staple cartridge.
The finisher controller circuit does not drive the staple/fold motor (FFSM)
unless the staple safety switch (SSS) is ON (the swing guide is close).
This assures safety in case you put your finger in the stapler.

(1)Stapler Movement Controller
The stapler unit is moved by the slide motor (FSM). Its home position is
detected by the slide home position sensor (SHPS). The stapler waits at
the back irrespective of the staple mode and paper size. After paper has
been stacked on the processing tray, the stapler is moved to the specified
stapling position in response to the stapling command from the host
machine.
F02-304-03 shows the standby position of the stapler and the stapling
position depending on the staple mode.
a.Front 1-point stapling
The stapler waits at the back. The stapler moves to and returns from the
stapling position for each stapling operation.
b.Rear 1-point stapling
The stapler waits at the back. The stapling position is the same as the
standby position.

c.Middle 2-point stapling
The stapler waits at the back. The stapler moves to and returns from the
stapling position for each stapling operation. The stapler first staples a
paper stack at the rear stapling position and then staples it at the front
stapling position.
