Adc Sensor - Xerox DocuColor 2240 Service Manual

9-654 ADC Sensor

The machine logic detected an ADC Sensor operation failure.
Procedure
The machine is a DC3535.
Y N
Check ADJ 9.4. The fail judgement of the ADC Sensor is OK.
Y N
There is +5VDC from P/J536-A13 on the I/F PWB
Y N
Go to Figure 1. Check the wires and connectors. If the check is OK, replace the
I/F PWB (PL 9.1). If the problem continues replace the MCU PWB
Enter dC330 [009-078] and press Start. The ADC Shutter Solenoid energized
1.3).
Y N
Check the wires and connectors. If the check is OK, replace the I/F PWB
9.1). If the problem continues replace the MCU PWB
Enter dC330 [009-078]. There is 0VDC from P/J536-A8 on the I/F PWB to GND.
Y N
Check the wires and connectors. If the check is OK, replace the I/F PWB
9.1). If the problem continues replace the MCU PWB
Enter dC330 [009-079]. The voltage from P/J536-A6 to GND changed to 0VDC
momentarily.
Y N
Check the wires and connectors. If the check is OK, replace the I/F PWB
9.1). If the problem continues replace the MCU PWB
Check the wires and connectors. If the check is OK, replace the ADC Sensor
Assembly (PL 1.3).
After checking that no failures are detected during normal operation, go to call closeout.
Check ADJ 9.4. The fail judgement of the ADC Sensor is OK.
Y N
There is +5VDC from P/J536-A11 on the I/F PWB
Y N
Go to Figure 2. Check the wires and connectors. If the check is OK, replace the I/F U
PWB (PL 13.1).
Enter dC330 [009-078] and press Start. The ADC Shutter Solenoid

Check the wires and connectors. If the check is OK, replace the I/F PWB. If the prob-
lem continues, replace the MCU PWB
Enter dC330 [009-078] and press Start. There is 0VDC from P/J536-A6 on the I/F
