Status Indicator RAPs
Initial issue
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 document exits the
DADF.
YN
Go to the RAP for the displayed status code.
Enter dC330 [005-119] and press Start. Actuate the Duplex Sensor (PL 20.7). The display
changes.
YN
The display indicates High
YN
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.
YN
+24 VDC is measured at P/J598-4 on the DADF Control PWB.
YN
Replace the DADF Control PWB (PL 20.3).
+24 VDC is measured at J598-5 on the DADF Control PWB.
YN
Go to Flag 3 and Flag 4. Check the wires for an open circuit. If the wires are good,
replace the Registration Gate Solenoid (PL 20.2).
Enter dC330 [005-075]. Select Start. The voltage at P/J598-5 drops to less than +1.0
VDC.
YN
Replace the DADF Control PWB (PL 20.3).
Check the Registration Gate Solenoid linkage for binding. If the linkage is good, replace
the Registration Gate Solenoid (PL 20.2).
Open the Document Feed Assembly and block the Registration Sensor with a sheet of paper.
The display changes.
YN
Go to the 5-702 Registration Sensor RAP
Check Following:
• Check the Duplex Lower Chute for warping (PL 20.7). Replace the chute if it is warped
more than 0.6 mm end-to-end.
• Check the pinch rolls in the duplex drive area (PL 20.7)
• Check the DADF Transport Height (ADJ 5.4). Adjust if necessary.
• The Platen Belt for contamination, wear and a rotation failure (PL 20.10).
• The Platen Belt for an improper tension (REP 5.19).
