4-163
Fault code indicates that the Stacker motor (ST-M1) has an open circuit.
Initial Actions
• Ensure that the connectors are properly installed on the Stacker Motor (PL 6.0).
• If a Trimmer is installed:
Ensure that plug B.P2, J/PM1 and J/P28 are connected.
• Check that the Belt Stacker cable is connected to the Booklet Maker.
Procedure
• Disconnect the motor plug M1.
• Enter Service (GP1) mode and start Stacker motor (ST-M1) in (GP4) check motors.
• Measure VDC between the red wire M1 and the black wire M1 (PWM 30V and GND).
The voltage is 24 VDC ± 10%.
Y N
• Disconnect plug P2 from PCB “B”. (PL 4.0)
• Measure VDC between J.2-4 and J.2-11 (PWM 30V and GND).
The voltage is 24 VDC ± 10%.
Y N
Replace MD6DC PCB “B” (PL 4.0).
