Just After the Power is Switched on

At power on, the motor [A] moves the upper tray to the start position just under the
feed-out slot. The motor stops when the paper height sensor [B] detects the tray.

Height Adjustment During Feed-Out

The upper tray moves up and down on a rack and pinion on a movable side fence
that remains locked in place during copying.
When the top of the stack actuates the sensor [B], a solenoid [C] inside the upper
tray releases a locked one-way clutch long enough to lower the upper tray a short
distance on its track to allow more pages to feed out. This process repeats until the
tray is full.

Upper Tray Full

When the tray is full, a metal actuator [G] on the side of the upper tray frame
actuates the upper tray full sensor [D] and the job stops.
The paper sensor [E] inside the upper tray detects when the stack is removed from
the tray, and the tray returns to the initial position at the feed-out slot. The upper
limit switch [F] (a micro-switch) is a backup if sensor [B] fails to stop the tray.
