Y N
Repair the open circuit or short circuit.
Measure the voltage between the DADF PWB (PL 15.3P786-1 (+) and GND (-) (BSD 5.2
Flag 5). The voltage is approx. +24VDC.
Y N
Replace the DADF PWB (PL 16.3).
Replace the DADF Nudger Motor (PL 16.6) If the problem persists, replace the DADF
PWB (PL 16.3).
Replace the DADF PWB (PL 16.3).

005-284 DADF APS Sensor Logic RAP
BSD-ON:5.4
The combinations of outputs from the DADF APS 1 Sensor, DADF APS 2 Sensor and DADF
APS 3 Sensor are abnormal.
Initial Actions
• Power Off than On
Procedure
Execute Component Control [005-218]. Actuate the DADF APS 1 Sensor with paper. The dis-
play changes.
Y N
Check the connections of P/J777 and P/J761. P/J777 and P/J761 are connected cor-
rectly.
Y N
Connect P/J777 and P/J761.
Check the wire between J777 and J761 for an open circuit or a short circuit (BSD 5.4 Flag
7/Flag 8). The wire between J777 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 P761-6 (+) and GND (-) (BSD 5.4 Flag 8).
The voltage is approx. +5VDC.
Y N
Replace the DADF PWB (PL 16.3).
Measure the voltage between the DADF PWB P761-5 (+) and GND (-) (BSD 5.4 Flag 7).
Actuate the DADF APS 1 Sensor with paper. The voltage changes.
Y N
Replace the DADF APS 1 Sensor (PL 16.7).
Replace the DADF PWB (PL 16.3).
Execute Component Control [005-219]. Actuate the DADF APS 2 Sensor with paper. The dis-
play changes.
Y N
Check the connections of P/J778 and P/J761. P/J778 and P/J761 are connected cor-
rectly.
Y N
Connect P/J778 and P/J761.
Check the wire between J778 and J761 for an open circuit or a short circuit (BSD 5.4 Flag
9/Flag 10). The wire between J778 and J761 is conducting without an open circuit
or a short circuit.
Y N
Repair the open circuit or short circuit.
