3.3.2 Tray Ascent/Descent Control
0020-4688
The tray A/B is moved up or down by controlling 2 motors (M22, M23) in response to the instructions from the finisher controller.
The machine uses 2 sensors (PS34, PS35) to check for faults in these motors.
The sensor monitors the rotation of the motors; when any of the following occurs, the finisher controller PCB will stop the drive to the motor and, at the same time,
will communicate the fact to the host machine:
[1] Tray B paper detection signal
[7] Tray A lift motor drive single
[2] Tray B paper surface detection light-emitting signal
[8] Tray A lift motor rotation detection signal
[3] Tray B paper surface detection light-receiving signal
[9] Auxiliary tray solenoid drive signal
[4] Tray A paper detection signal
[10] Tray B lift motor drive signal
[5] Tray A paper surface detection light-emitting signal
[11] Tray B lift motor rotation detection signal
[6] Tray A paper surface detection light-receiving signal
M22: Tray A lift motor
PS35: Tray B lift motor rotation sensor
M23: Tray B lift motor
UN15: Tray A paper side sensor board (emitter)
SL9: Auxiliary tray solenoid
UN16: Train A paper side sensor board (receiver)
PS32: Tray A paper sensor
UN17: Tray B paper side sensor board (emitter)
PS33: Tray B paper sensor
UN18: Train B paper side sensor board (receiver)
PS34: Tray A lift motor rotation sensor
Related Error Code
- E540 (fault in tray A)
While the tray A motor (M22) is rotating, the tray A lift motor rotation detection signal is absent for 250 msec or more.
- E542 (fault in tray A)
While the tray B motor (M23) is rotating, the tray B lift motor rotation detection signal is absent for 250 msec or more.
