Status Indicator RAPs Initial issue
5-110 Registration Sensor On
The Registration Sensor did not detect a document within 800 msec. after the Feed Motor
energized.
Initial Actions
• This fault can be caused by the following operator errors:
– Pulling the document out of the DADF while it is being fed.
– Loading too many documents or documents that are not in specification for the
DADF (incorrect size or quality, staples or paper clips, etc.).
Instruct the operator how to operate the DADF.
• Ensure document path is clear. Look for pieces of paper that could be blocking the Regis-
tration Sensor or the document path.
• Ensure Feed and Nudger Rolls are free of contamination and wear ( PL 20.4 ).
Procedure
Clear the jam if one exists. Place a document in the DADF and press the Start button. The
document prefeeds into the DADF.
