Initial issue
Status Indicator RAPs
5-111 Registration Sensor Off
The document did not deactuate the Registration Sensor within 1000 msec after the DADF Belt
Motor energized.
Initial Actions
This fault can be caused by an operator loading a large quantity of documents with too much
curl. Question the operator to ensure the documents do not contain too much curl.
Check the customer’s documents to ensure they meet DADF specifications. Some documents,
such as coated paper, have a high amount of adhesion and will not move freely through the
DADF. Documents over 128 gsm may cause this problem in the DADF.
Ensure that the Platen Belt is properly aligned on the transport. Visually check the alignment of
the Platen Belt with the registration guide on the rear edge of the Platen Glass (PL 20.11).
Align or replace the Platen Belt if necessary (PL 20.10).
If the problem is caused by multi-sheet feeds, check the Retard Rolls (PL 20.5).
Ensure the document path is clear.
Procedure
Remove the following:
• Front Cover (PL 20.1)
• Entrance Tray (PL 20.1)
• Lower Chute Assembly (REP 5.8)
• Rear Cover (REP 5.18)
Enter dC330 [005-055]. Select Start and observe the Platen Belt. The Platen Belt rotates.

Go to the 5-703 DADF Belt Motor RAP.

drive faults (broken drive belts, rolls not turning, etc.). Repair any obvious problems.
Clear any jam. Enter dC330 [005-110]. The display indicates H.
