005-122 CVT Simplex/Side1 Pre-Registration On Jam RAP
BSD-ON:5.4/5.5
• After the Pre Feed operation started for the first sheet (DADF Feed Motor On (CW)) in
Duplex or Simplex mode, the Pre-Registration Sensor did not turn On within the specified
time.
• After the Pre Feed operation started for the second sheet onwards (DADF Feed Motor On
(CW)) in Duplex mode, the Pre-Registration Sensor did not turn On within the specified
time.
Initial Actions
• Power Off than On
Procedure
Execute Component Control [005-206]. Actuate the DADF Pre Registration Sensor with paper.
The display changes.
Y N
Check the connections of P/J781 and P/J761. P/J781 and P/J761 are connected cor-
rectly.
Y N
Connect P/J781 and P/J761.
Check the wire between J781 and J761 for an open circuit or a short circuit (BSD 5.4 Flag
3/Flag 4). The wire between J781 and J761 is conducting without an open circuit or
a short circuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between the DADF PWB P761-12 (+) and GND (-) (BSD 5.4 Flag
4). The voltage is approx. +5VDC.
Y N
Replace the DADF PWB (PL 16.3).
Measure the voltage between the DADF PWB P761-11 (+) and GND (-) (BSD 5.4 Flag 3).
Actuate the DADF Pre Registration Sensor with paper. The voltage changes.
Y N
Replace the DADF Pre Registration Sensor (PL 16.7).
Replace the DADF PWB (PL 16.3).
Execute Component Control [005-001]. The DADF Feed Motor starts up.
Y N
Check the connections of P/J764 and P/J754. P/J764 and P/J754 are connected cor-
rectly.
Y N
Connect P/J764 and P/J754.
Check the wire between J764 and J754 for an open circuit or a short circuit (BSD 5.5 Flag
1). The wire between J764 and J754 is conducting without an open circuit or a short
circuit.

Repair the open circuit or short circuit.
Measure the voltage between the DADF PWB P754-1 (+) and GND (-), and between
P754-7 (+) and GND (-) (BSD 5.5 Flag 1). The voltage is approx. +24VDC.
Y N
Replace the DADF PWB (PL 16.3).
Replace the DADF Feed Motor (PL 16.9) If the problem persists, replace the DADF PWB
(PL 15.3).
Replace the DADF PWB (PL 16.3).
