safety device to signal tray full in case the tray full sensor fails.

2. Rotating Shaft
3. Edge Depressor Solenoid
4. Actuator
5. Paper Height Sensor
While the feed-out belt motor is running, the tray lift motor switches on (300 ms for shift
mode, 500 ms for stapling mode), lowers the output tray, stops, then waits to receive the
stack.
Just before a stack falls onto the output tray, the edge depressor solenoid (3) switches ON
and retracts the edge depressors (1) away from the top of the stack already on the tray so
that the next stack can fall freely.
The feed-out belt motor stops immediately after the stack has fallen between the side
fences. The edge depressor solenoid switches OFF, and the edge depressors fall onto the
trailing edge of the stack against the end fence.
