Tray Ascent/Descent Control
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:
Related Error Code

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.
