3.4 Stapler Unit
The staple/fold motor (M7) 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 po-
sition sensor (PI19).
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 staple cam
to the original position.
The staple empty sensor (PI20) 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 (PI21) 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 (M7) unless the staple
safety switch (MS3) is ON (the swing guide is close). This assures safety in case where you
happen to put your finger in the stapler.
