Make sure that the class understands how the sensor at the bottom of the tray
(right tray paper end sensor) saves time when checking if the tray has any paper or
not before starting to lift the tray to the paper feed position.

There are two tray lowering mechanisms.
¾
Mechanism 1. When the user pulls the tray out, the tray falls under its own
weight, slowed by a damper.
¾
Mechanism 2. When the stack in the right side has finished, the tray bottom
plate must lower automatically before the stack in the left side can move
across. The tray lift motor lowers the plate until the tray down sensor detects
the actuator on the bottom plate. Then the stack in the left side can move
across.
