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

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.
