Initial issue
5-900 Document Sensor Timing
One of the following DADF Interlocks was opened during DADF operation:
• DADF Interlock Switch (PL 20.3)
• Top Cover Interlock Switch (Front) (PL 20.2)
• Top Cover Interlock Switch (Rear) (PL 20.2)
Initial Actions
If the problem appears to be operator caused, instruct the operator on proper DADF operation.
Check the interlock to be sure it is operational and is mounted correctly.
Procedure
Switch the power off then on. Run the DADF. The problem continues.
YN
Return to Service Call Procedures.
Check all DADF Interlocks for an intermittent condition. Ensure they are mounted correctly and
that all connectors are securely connected. Replace any Interlock that does not function cor-
rectly. If the problem continues, replace the DADF Control PWB (PL 20.3).
5-901 Power On Document Present
The Document Sensor detects a document at Power On.
Initial Actions
Clean the Document Sensor. Ensure there are no pieces of paper on the sensor.
Procedure
Enter dC330 [005-102] and select Start. The display indicates H.
YN
Disconnect P/J599 from the DADF Control PWB. The display changes to H.
YN
Replace the DADF Control PWB (PL 20.3).
Go to Flag 1. Check the wires for an short circuit. If the wire is good, replace the Docu-
ment Sensor (PL 20.5).
The Document Sensor appears to be functioning correctly. Check the wires from the sensor to
the DADF Control PWB. Look for loose connectors/pins. If the problem continues, replace the
Document Sensor (PL 20.5). If the problem continues, replace the DADF Control PWB (PL
20.3).
