CHAPTER 2 FINISHER UNIT BASIC OPERATION
F.
Stapler Unit
Stapling is executed by the staple motor (M6). A single rotation of the cam by the motor results
in one stapling operation.
The cam is checked by the staple home position sensor (PI22) to find out whether it is at the
home position.
The stapler motor is controlled by the microprocessor (IC1) on the finisher controller so that it
is rotated clockwise or counterclockwise.
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 the staple cartridge is detected by the staple switch (MS8). The pres-
ence/absence of staples inside the staple cartridge is detected by the staple detecting switch (MS9).
The staple edge sensor (PI21) is used to find out whether a staple has been edged out to the end of
the cartridge.
The finisher controller PCB does not drive the staple 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.
