C. Delivery Operation after Stapling
When stapling is complete, the finisher controller PCB drives the
stack delivery motor (FAM) in the forward direction to feed the
paper stack (sandwiched between the stack delivery rollers) in the
delivery direction. The delivery belt home position sensor (FOB-
HPD) is turned OFF. The stack delivery motor (FAM) is driven a
specified number of pulses, causing the swing guide to ascend. At
the same time, the staple shift motor (FSM) is driven to return the
stapler back to the standby position, followed by driving of the stack
delivery motor (FAM). Then, the paper stack is delivered with the
nails of the delivery belt that rotates in sync with the stack delivery
rollers.

D. Stapler Unit
The staple 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 drive home position sensor
(FSHPD).
The staple motor (FFSM) is rotated in the forward or reverse direc-
tion under the control of the macro computer (IC13) on the finisher
controller PCB.
When the staple drive home position sensor (FSHPD) is OFF, the
finisher controller PCB rotates the staple motor (FFSM) in the for-
ward direction until the sensor turns ON, allowing the staple cam to
the original position.
The staple empty sensor (FSD) is used to detect presence/
absence of a staple cartridge in the machine. The self prime sensor
(FSPD) is used to detect presence/absence of staples in the car-
tridge.
The finisher controller circuit does not drive the staple motor
(FFSM) unless the staple safety switch (FSSSW) is ON (the swing
guide is close). This assures safety in case where you happen to
put your finger in the stapler.
