10-106 Fuser Exit Sensor Off Jam RAP
The Fuser Exit Sensor did not deactuate within the specified time after the Registration Feed
started.
Initial Actions
Refer to BSD 10.7, 10.12 and 10.9 for the following procedure.
Check for the following:
• Clean the Fuser Exit Sensor
• Obstructions in the paper path or damage on l
ead edge of sheets
• Contamination on the Regi Roll, 2 nd BTR or Vacuum Transport.
• Ensure that connectors P/J412B, P/
J413A, 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 010-005 Inverter Gate Solenoid (Exit). P
ress Start. The Inverter Gate Sole-
noid energizes.
YN
+24 VDC is measured between P/
J412B-9 an
d GND.
YN
+24 VDC is measured between P/
J412B-8 and
GND.
YN
Replace the IOT Drive PWB (PL 9.
2).
Go
to Flag 3 on BSD 10.7 and check the harness for an open circuit. If the harness is
good, replac
e the Inverter Gate Solenoid (PL 2.25).
Press Start. Th
e voltage at P/J412B-9 momentarily goes to less than +1.0 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2).
Replace the Inverter Gate Solenoid (PL 2.25
).
Enter dC330 010-006 Inverter Gate Solenoid (Invert). Pr
ess Start. The Inverter Gate Sole-
noid energizes.
YN
+24 VDC is measured between P/
J412B-7 and
GND.
YN
Go to F
lag 4 on BSD 10.7 and check the harness for an open circuit. If the harness is
good, replac
e the Inverter Gate Solenoid (PL 2.25).
Press Start. Th
e voltage at P/J412B-7 momentarily goes to less than +1.0 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2).
Replace the Inverter Gate Solenoid (PL 2.25
).
Enter dC330 010-033 Oil Pump. Pre
ss Start and Stop several times. The Exit Motor ener-
gizes and deenergizes.
YN
Press St
op. App
roximately +7 VDC is measured between P/J418B-17 on the IOT
Drive PWB and GND.
YN
Go to Fl
ag 1 and Fl
ag 3 on BSD 10.9 and check the harness for an open circuit. If
the harness is good, replace the Exit Motor (PL 1.6).
Press Start. Th
e voltage at P/J418B-17 goes to less than +1.0 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2).
+24 VDC is measured between P/J418B-19 and
GND on the IOT Drive PWB.
YN
Replace the IOT Drive PWB (PL
9.
2).
Go to Flag 2 on BS
D 10.9 and check the harness for an open circuit. If the harness is
good, replace the Exit Motor (PL 1.6). If the problem continues, replace the IOT Drive
PWB (PL 9.2).
Check for obvious damage, missing and/or broken
Fu
ser Exit Drive gear assemblies and drive
belts that would cause the paper to be slow to leave the Fuser Exit Sensor (PL 1.6). Also,
cheat the Front Door Interlock and remove the Oil Bottle. Visually observe the paper as it feeds
into and through the Fuser. Ensure that the Fuser Nip stays engaged until the trail edge of the
sheet exits the Fuser.
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).
