005-133 CVT Invert Sensor Off Jam
BSD-ON:5.4
Invert Sensor does not turn Off in specified time from Out Sensor Off in Duplex Mode.
Procedure
If the problem occurs frequently, check the following:
1. There is any area in document path that interferes with document feed.
2. Any foreign substance is attached to Roll surface.
3. Roll surface has worn abnormally.
4. Simp/Dup Gate is in normal position (Simp/Dup Gate Solenoid operation included.)
5. Platen Motor rotates normally.
6. Feed Motor rotates normally.
7. Invert Roll performs Nip operation normally (Nip Release Solenoid operation included)
8. Check the connectors and wires for damage.
If all above are OK, replace Invert Sensor (PL 16.7). If the problem continues, replace the Out
Sensor (PL 16.9) If the problem persists, replace the DADF PWB (PL 16.3).

Initial Actions
• Power Off than On
Procedure
Execute Component Control [005-211]. Actuate the DADF Invert Sensor with paper. The dis-
play changes.
YN
Check the connections of P/J780 and P/J761. P/J780 and P/J761 are connected cor-
rectly.
YN
Connect P/J780 and P/J761.
Check the wire between J780 and J761 for an open circuit or a short circuit (BSD 5.4 Flag
5/Flag 6).
The wire between J780 and J761 is conducting without an open circuit or
a short circuit.
YN
Repair the open circuit or short circuit.
Measure the voltage between the DADF PWB P761-9 (+) and GND (-) (BSD 5.4 Flag 6).
The voltage is approx. +5VDC.
YN
Replace the DADF PWB (PL 16.3).
Measure the voltage between the DADF PWB P761-8 (+) and GND (-) (BSD 5.4 Flag 5).
Actuate the DADF Invert Sensor with paper. The voltage changes.
YN
Replace the DADF Invert Sensor (PL 16.7).
Replace the DADF PWB (PL 16.3).
Execute Component Control [005-026]. The DADF Registration Motor starts up.
YN
Check the connections of P/J765 and P/J755. P/J765 and P/J755 are connected cor-
rectly.
YN
Connect P/J765 and P/J755.
Check the wire between J765 and J755 for an open circuit or a short circuit (BSD 5.5 Flag
