2.1.1 Functional Construction

The puncher unit is optionally installed in the feed path between the host machine and finisher. The puncher unit does
not have a paper feed mechanism; paper is fed with the rollers of the host machine (main body/finisher). Upon
detection of the trailing edge of the fed paper, the puncher unit stops the paper temporarily and rotates the punch shaft
to punch holes along the trailing edge of the paper. The above operations are controlled by the finisher controller
PCB and every part of the puncher unit are driven under the control of the punch controller PCB.
