The main motor drives the transport rollers which move the media along the paper path. The sensor (pass through)
detects if the media has entered the mailbox. Four diverters control which way the media will go. If a diverter is opened,
then media will pass through it and go to the next diverter above it. The media finally exits when it encounters a closed
diverter.
Upon exit, the media is fed out by the exit rollers towards the assigned output bin. The sensor (bin full) verifies if the
media has exited. The media level on the output bin is detected by the actuator flag. When the output bin is full, the
actuator flag triggers the sensor (bin full). A signal will be sent to the printer:
• to prompt the user to clear the output bin
• to change the direction of the paper path, re-routing it to another available output bin.
Staple finisher theory
The staple finisher is capable of compiling multiple pages and stapling them into one document. Motors drive the
stapling process and sensors detect the media's position and location.

When the finisher is installed on top of the printer, the diverter plunger changes the position of the diverter below it.
Since the diverter position of the printer below is opened, the printed paper will be re-routed. Instead of exiting the
standard output bin, the media enters the staple finisher. The movement of the diverter plunger can be controlled by
its diverter motor, depending on the printer's commands.
Note: The diverter motor controls the diverter below it. Another way of saying it is that the diverter is controlled by
the diverter motor of the output option above it.
The main motor drives the rollers which move the media along the paper path. The sensor (pass through) detects if
the media has entered the staple finisher.
