Mailbox theory
The mailbox is capable of delivering printed media into multiple separate output destinations. This allows multiple
users to automatically segregate the printed output. All of the user's printed outputs can be exited into the specific
output bin assigned to him. The mechanism is controlled by a set of sensors that detect the media and drive motors
that move the media along its paper path.

When the mailbox 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 mailbox. 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.
