5-500 Dadf No Originals Rap; 5-501 Dadf Document Size Irregular Rap - Xerox DocuColor 12/DCCS50 Service Manual

5-500 DADF No Originals RAP

The DADF Control PWB detected that the original was removed from the Entrance Tray after
the DADF started operating.
Initial Actions
Return the removed originals to the Entrance Tray and attempt to run the job again. If no origi-
nals were removed, proceed with this RAP.
Check for the following:
• The Side Guide can be properly adjusted against the stack.
• Contamination on the DADF Document Sensor.
• Ensure that connectors P/J599 and
PWB and DADF Document Sensor and there are no obvious crimped or broken wires.
• Refer to BSD 5.2 for the following procedure.
Procedure
Enter dC330 005-102 Document Sensor. Press Start. Block the DADF Document Sensor.
The display changes from H to L.
Y N
Less than +1 VDC is measured at P/J599-5 on the DADF Control PWB.
Y N
+5 VDC is measured between P/J581-1 and P/J581-3 on the DADF Document
Sensor.
Y N
Go to Flag 5 on BSD 5.2 and check the wires for an open circuit. If the harness
and connectors are OK, replace the DADF Control PWB
Go to Flag 4 on BSD 5.2. Check the wire for an open circuit. If the wire is good,
replace the DADF Document Sensor

5-501 DADF Document Size Irregular RAP

The Control Logic has detected that a automatically-detected size of the original was irregular.
Initial Actions
Check for the following:
• Ensure that the Document Handler is free of any paper or debris.
• Ensure that connectors P/J599,
Control PWB and DADF Size Sensors 1 and 2, and there are no obvious crimped or bro-
ken wires.
• Refer to BSD 5.3 for the following procedure.
Procedure
Enter dC330 005-150 #1 Size Sensor. Press Start. Block DADF Size Sensor 1. The display
changed from H to L.
Y N
With the sensor blocked, less than +1 VDC is measured at P/J599-8 on the DADF
Control PWB.
Y N
With the sensor blocked, less than +1 VDC is measured at P/J582-2 on DADF
Size Sensor 1.
Y N
There is +5 VDC between P/J582-1 and P/J582-3 on the DADF Size Sen-
sor 1.

changed from H to L.
Y N
With the sensor blocked, less than +1 VDC is measured at P/J599-11 on the DADF
Control PWB.
Y N
With the sensor blocked, less than +1 VDC is measured at P/J583-2 on the
DADF Size Sensor 2.
Y N
There is +5 VDC between P/J583-1 and P/J583-3 on the DADF Size Sen-
sor 2.
