CF-005 CF-M16 Cover Drive Motor Open Circuit
This Fault Code indicates that the Cover Drive motor CF-M16 has an Open circuit.
Initial Actions
• Make sure that plug C P2 on MD6DC PCB “C” in the Booklet Maker is connected.
• Make sure that jack/plug J33/P33 and J32/P32 in the Cover Feeder is connected.
Procedure
Disconnect motor plug M16 and C,P2 from PCB “C”.
1 Check wire for Continuity / Short circuit the Orange wire from M16 to C,P2-4
2 Check wire for Continuity / Short circuit from Violet wire from M16 to C,P2-11
Is there Continuity and no short circuit between Orange and chassis/GND, Violet and chassis/GND
Y N
Replace/Repair wire Harness.

between the orange wire M16 and the violet wire M16 (Motor power +/-).
The voltage is 30 VDC +/- 10%.
Y N
Disconnect plug C.P2 from MD6DC PCB “C”. Measure between J2-4 and J2-11 (30V and GND).
The voltage is 30 VDC +/- 10%.
Y N
Replace MD6DC PCB “C”.
Repair wire Harness.
Replace motor M16.
WARNING
