12.1.2.6.1. Basic Operations
1. Outline
The Punch Unit is an option and is designed for installation to the Pickup Assembly of the Finisher. The
Punch Unit is not equipped with a paper feeding mechanism, and the sheets from the Host Machine
move through the Punch Unit and then the feed system of the Finisher.
When the trailing edge of a sheet from the Host Machine reaches the Punch Unit, the sheet is stopped
once, and the Punch Shaft is rotated to punch a hole along the trailing edge. These operations are
controlled with various commands from the Finisher Controller PCB as well as the commands from the
Punch Controller PCB.
