11.1.2.2.6. Staple Unit
Stapling is executed by the Stapler Motor (M6). A signal rotation of the cam by the motor results in one
stapling operation.
The cam is checked by the Stapling Home Position Sensor (PI22) to find out whether it is at the home
position.
The Stapler Motor is controlled by the Microprocessor (Q1) on the Finisher Controller so that it is rotated
clockwise or counter-clockwise.
When the Stapling Home Position Sensor is off, the Finisher Controller PCB rotates the Stapler Motor
clockwise until the sensor turns on so as to return the Stapling Cam to its initial state.
The presence/absence of staples inside the Staple Cartridge is detected by the Staple Detecting Switch
(MS9). The Finisher Controller PCB does not drive the Stapler Motor (M6) unless the Swing Guide Closed
Detecting Switch 2 (MS6) is on (i.e., the swing guide is closed). This is to protect against injuries that could
occur when a finger is stuck inside the Stapler.
