12.1.2.3.4. 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 Position Sensor (PI19).
The Staple/Fold Motor is rotated in the forward or reverse direction under the control of the Micro 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 Staple 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 closed). This assures safety in case where you happen to put your finger
in the stapler.
