Overview
The output tray motor gear lifts/lowers the tray if the stack height is not at the
target position.
The output tray motor turns the two sector gears. These gears keep the tray
at the same angle during up/down movement.
Output Tray Downward Movement
The top of the paper stack is checked after every page (or set of pages) has
been fed out. If the top of the stack is higher than the target level, the output
tray motor moves the tray down.
When the tray lower limit sensor detects the actuator on the sector gear (the
gear on the left in the diagram), a stack near-limit signal is transferred to the
main frame. The tray cannot move any lower. The next time the top of the
stack height is above the target level, printing stops.
Output Tray Upward Movement
If paper is removed from the stack, the top of the stack will be lower than the
target level, and the output tray motor moves the tray up.
When the tray upper limit sensor detects the actuator on the other sector
gear, the tray cannot be moved up any more, so the motor stops.
