5.1 Basic Construction
5.1.1 Functional Construction
The puncher unit is optionally installed in the delivery path between the host machine and the finisher.
When the paper delivered from the host machine reaches the puncher unit, it is fed by the punch feed roller. Then
when the trailing edge of the paper is detected, the paper is tempo-rarily stopped and the punch axis rotates to punch
holes in the trailing edge of the paper. These operations are controlled by the finisher controller PCB and the punch
controller PCB drives each puncher component.
