Registration Sensor Inversion - Xerox DocuColor 2240 Service Manual

5-112 Registration Sensor Inversion

The document does not actuate the DADF Registration Sensor within 1000 msec after the Belt
Motor energized for document inversion.
Initial Actions
This fault can be caused by using documents with too much curl. Check the documents and
inform the operator.
Procedure
Load a document in the DADF, select 1 to 1 and make a copy. The

Go to Flag 1. Check the wire for a short circuit to GND.
Go to Flag 1 and Flag 2. Check the wires for an open circuit. If the wires are good, replace
the Duplex Sensor (PL 20.7). If the problem continues, replace the DADF Control PWB
(PL 20.3).
Enter dC330 [005-075] and press Start. The Registration Gate Solenoid energizes.

Replace the DADF Control PWB
+24 VDC is measured at J598-5 on the DADF Control PWB.
Y N
Go to Flag 3 and Flag 4. Check the wires for an open circuit. If the wires are good,
replace the Registration Gate Solenoid
Enter dC330 [005-075]. Select Start. The voltage at P/J598-5 drops to less than +1.0
VDC.

Replace the DADF Control PWB
Check the Registration Gate Solenoid linkage for binding. If the linkage is good, replace
the Registration Gate Solenoid (PL

• Check the pinch rolls in the duplex drive area
• Check the DADF Transport Height
• The Platen Belt for contamination, wear and a rotation failure
• The Platen Belt for an improper tension
