Overview

This unit is installed between the saddle unit and saddle delivery tray of the saddle finisher. It
stops the center bound booklet for a moment to trim the fore edge.
The booklet loaded from the saddle unit is fed by the inlet roller. When the leading edge of
the media (back of the booklet) reaches a prescribed location, the booklet is stopped for a
moment and registered. Then it is fed to the trim position and the fore edge of the booklet is
trimmed.
The name and role of motors, solenoids, and sensors used for trimming are shown below.
