10-105 Fuser Exit Sensor On Jam RAP
The Fuser Exit Sensor did not actuate within the specified time after the IBT Entrance Sensor
actuated.
Initial Actions
• Refer to BSD 10.7, 10.12 and 10.4 for the following procedure.
• Ensure that 605K91060 Pressure Roll Finger Assembly Kit, Tag 11, is installed.
NOTE: This problem is common when heavyweight paper is
fed from the tray long-edge first.
All heavyweight and extra-heavyweight paper should be fed from the tray short-edge first.
Check for the following:
• Clean the Fuser Exit Sensor
• Cheat the Front Door Interlock and remove the Oil Bottle. Visually observe the paper on
the V
acuum Transport to see that it stays down. If not, orient the paper so it feeds from the
tray short-edge first. If the problem remains, ensure that the Fuser Nip is cammed in
before the sheet arrives.
• Skewed sheets with LE corner damage.
• Obstructions in the paper path or damag
e on l
ead edge of sheets
• Ensure that the Fuser Inlet Baffle is correctly positioned
• Contamination on the Vacuum Transport
• Damage to Vacuum Transport Drive Gears
• Ensure that connectors P/
J413A, P/
J417B, P/J418B and P/J168 are seated correctly
on the IOT Drive PWB and the Fuser Exit Sensor, and there are no obvious crimped or
broken wires.
Procedure
Enter dC330 010-105 Fuser Exit Sensor. Press Start. Block the Fuser Exit Sensor with a
sheet of paper. The display changes from H to L.
YN
The display indicates a constant H.
YN
Go to Fl
ag 1 on BSD 10.
7 and check the harness for a short circuit. If the harness is
good, replace the Fuser Exit Sensor (PL 8.10).
Connect the meter from P/J413A-4 on t
he IOT Drive PWB to GND. Block the Fuser Exit
Sensor with a sheet of paper. The voltage at P/J413A-
4 goes from +5 VDC when the
sensor is not blocked, to less than +1.0 VDC when the sensor is blocked.
YN
There is +5 VDC between P
/J413A-
14 and GND on the on the IOT Drive PWB.
YN
Go to Fl
ag 2 on B
SD 10.7 and check the harness for a short circuit. If the har-
ness is good, replace the IOT Drive PWB (PL 9.
2).
Go to Flag 1 and Fl
ag 2 on BSD 10.7 and check the harness for an open circuit. If
the harness is good, replace the Fuser Exit Sensor (PL 8.10). If the problem contin-
ues, replace the IOT Drive PWB (PL
9.2).
Replace t
he IOT Drive PWB (PL 9.2).
Ent
er dC330 004-009 Fuser Motor. Press Star
t and Stop several times. The Fuser Motor
energizes and deenergizes.
YN
Press St
op. + 5 V
DC is measured between P/J417B-11 and GND on the IOT Drive
PWB.
YN
+5 VDC is measured between P/
J42-8 an
d P/J42-7 on the Distribution PWB.
YN
Replace the Distribution PWB (PL
9.
3).
Go to Flag 1 and Flag 4 on BSD 10.4 and check the harnesses for an open circuit. If
th
e harnesses are good, replace the Fuser Motor (PL 1.6)
Press Start. Th
e voltage a P/J417B-11 go to less than +1.0 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2).
+24 VDC is measured between P/J42-6
on the Distribution PWB and GND.
YN
Replace the Distribution PWB (PL
9.
3).
Go to Flag 2 and Fl
ag 3 on BSD 10.4 and check the harnesses for an open circuit. If the
harnesses are good, replace the Fuser Motor (PL 1.6). If the problem continues, replace
the IOT Drive PWB (PL 9.2).
Check/replace the following components until the problem is resolved. Replace any compo-
nent that is worn, broken, bent,
deform
ed, binding or slipping:
• Heat Roll Stripper Fingers (PL 8.3) and Pressure Roll
Stripper Fingers (PL 8.10)
• Heat Roll Finger Assembly (PL 8.
3) and the Pressure Roll Finger Assembly (PL 8.10)
• Gears and shafts on the Fuser Exit Drive Assembly (PL 1.6)
Ensure that the rubber sleeve on the Exit Roll (shaft) (located under the Fuser Exit Sensor) is
not t
orn, damaged or contaminated with Fuser Oil. Clean the sleeve or repair it by replacing the
Exit Roll (shaft) (PL 8.10).
