Principles of Operation
Revision - Xerox Internal Use Only
Finisher
The Finisher is a customer installed option that adds hole punching, stapling (up to 50 sheets)
and job stacking with offset (up to 500 sheets). The Finisher docks with the printer and receives
power and control signals through an option connector located in the Top Cover. The opera-
tional descriptions presented in this section cover all the capabilities of the Finisher.
Finisher Media Path Components
The Finisher media path is described below:
• Compiler Tray’s function is to align media in preparation for stapling and offset.
• Exit section delivers media from the Compiler Tray to the Stacker Tray.
What follows is an overview of the way each of these sections operate and the components
involved. The Finisher paper path begins at the printer’s exit.
Media directed to the Finisher is fed out the IOT exit into the Finisher. As the media enters the
Finisher it is detected by the Entrance Sensor activating the entrance roller driven by the Fin-
isher Transport Motor. The Top Exit Roller is also driven by the Finisher Transport Motor and
ejects media into the Stacker Tray, Figure 1.
Stapled or aligned sets on the Compile Tray are held between the Eject Clamp and the Eject
Roller Shaft. The clamp paddles attached to the Eject Roller Shaft transfer the compiled sets
from the Compile Tray to the Stacker Tray.
Finisher Media Path Sensors
Sensors along the Finisher media path. See earlier illustrations for the location of each sensor.
Punch, Staple, Stacker, and Compile Tray sensors are listed separately with each component
description, Figure 1.
• Exit Gate Sensor
Detects IOT exit gate position. The exit gate actuator is actuated by the exit gate cam
driven by the entrance motor.
• Entrance Sensor
Senses the arrival of media from the printer into the Finisher media path.
• Exit Sensor
Detects media as it passes through the Exit Sensor. The Exit Sensor signal goes High
when the actuator is driven out of the sensing area.
• Stacker Full Sensor
A reflective photo-sensor to detect the stack volume of paper in the Stacker Upper Tray.
