Stapling unit

• The Stapling operation is accomplished by a Cam rotated once with the Staple/Folding Motor.
• The Home position of this Cam is detected with the Staple Drive Home Position Sensor. If the Staple
Drive Home Position Sensor is OFF, the Staple/Folding Motor rotates in the forward direction until the
Sensor is blocked or the signal is ON, which designates that the position of the Cam is ready for the
next stapling operation.
• The Staple Detecting Sensor detects if the Staple Cartridge is in the Unit and if the staples are in the
Staple Cartridge.
• A Self-Priming Sensor detects if the staples are positioned at the end of the Staple Cartridge.
• This Finisher is equipped with the safety protection mechanism. The Staple/Folding Motor will not be
turned ON without an ON condition (with Swing Guide closed) of the Front and Rear Staple Safety
Switches.
