Status Indicator RAPs Initial issue
5-195 Document Size Mismatch
Different sized documents are detected in the NO MIX mode.
Initial Actions
This fault can be caused by the following:
• Mixed size documents are fed without selecting that option on the UI.
• There is too much curl in the documents being fed through the DADF.
• The documents are improperly loaded.
• The type of document being fed (coated paper, etc.)
Instruct the operator on proper DADF operation.
Procedure
Enter dC330 [005-150] and select Start . Actuate the DADF Size Sensor 1 (Rear) ( PL 20.5 ).
The display changes.

Go to Flag 1 . Check the wire for a short circuit to GND. If the wire is good, replace
the Size Sensor 1 (Rear) ( PL 20.5 ).
Go to Flag 1 and Flag 2 . Check the wires for an open circuit. If the wires are good, replace
the Size Sensor 1 (Rear) ( PL 20.5 ). If the problem continues, replace the DADF Control
PWB ( PL 20.3 ).
Enter dC330 [005-151] and press Start . Actuate DADF Size Sensor 2 (Front) ( PL 20.5 ). The
