BASIC OPERATION

A.

Outline

The puncher unit (option) is attached on the feed path between the host machine and the fin-
isher.
The puncher unit does not have a paper feed mechanism. Paper from the host machine is fed by
feed drive from the finisher via the puncher unit. When the trailing edge of the paper from the host
machine reaches the puncher unit, the paper stops temporarily, and the punch shaft is rotated to
punch the trailing edge of the paper. This operation is controlled by the finisher controller PCB, and
each of the parts on the finisher is driven by the punch driver PCB.
