005-280 DADF EPROM Failure RAP

The DADF-EEPROM failed during the Read/Write operation.
Initial Actions
• Refer to BSD 3.5.
Procedure
Check the connection of each DADF PWB connector. The connectors are connected cor-
rectly.
Y N
Connect the connectors.
Turn on the power again. [005-280] reoccurs.
Y N
Return to Service Call Procedures.
Replace the DADF PWB (PL 15.3).

005-284 DADF Auto Paper Selection Sensor Logic Failure
RAP
The combinations of outputs from the DADF APS 1 Sensor, DADF APS 2 Sensor and DADF
APS 3 Sensor are abnormal.
Initial Actions
• Refer to BSD 5.4.
Procedure
Execute Component Control[005-218]. Actuate the DADF APS 1 Sensor with paper. The dis-
play changes.
Y N
Check the connections of
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
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 P761-4 (+) and GND (-) (BSD 5.4
The voltage is approx. +5VDC.
Y N
Replace the DADF PWB
Measure the voltage between the DADF PWB P761-6 (+) and GND (-) (BSD 5.4
Actuate the DADF APS 1 Sensor with paper. The voltage changes.
Y N
Replace the DADF APS 1 Sensor
Replace the DADF PWB
Execute Component Control[005-219]. Actuate the DADF APS 2 Sensor with paper. The dis-
play changes.
Y N
Check the connections of
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
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.
Measure the voltage between the DADF PWB P761-1 (+) and GND (-) (BSD 5.4
10). The voltage is approx. +5VDC.
