■ Stapling Operation

● Overview
Stapling operation staples the prescribed number of copies with the stapler unit.
The staple position depends on the staple mode and paper size.
Whether the staple unit is at home position or not is detected by the stapler shift home
position sensor (PI110).
The stapler unit is equipped with a stapler alignment interference sensor (PI116).
The staple motor (M111) operation is prohibited when the stapler alignment interference
sensor (PI116) is ON.
This is to prevent stapling at the stopper and damaging the stopper when the stapler shift
motor (M105) is incorrectly adjusted.
When the power is turned on, the finisher controller PCB drives the stapler shift motor (M105)
to return the stapler unit to home position. If the stapler unit is already at home position, it
waits in that state.
