10-102 Pre Fuser Sensor On Jam RAP
The Pre Fuser Sensor did not actuate within the specified time after the Pre IBT Sensor actu-
ated.
Initial Actions
Refer to BSD 10.1 and 10.12 for the following procedure.
Check for the following:
• Clean the Pre Fuser and Pre IBT Sensor.
• Skewed sheets with LE corner damage.
• Obstructions in the paper path or damag
e on l
ead edge of sheets
• Contamination on the 2nd BTR Roll and/or Vacuum Transport.
• Ensure that connectors P/J420 and P/J157 ar
e seated correctly on the IOT Drive PWB
and the Pre Fuser Sensor, and there are no obvious crimped or broken wires.
Procedure
Enter dC330 010-100 Pre Fuser Sensor. Press Start. Open the Drawer and block the Pre
Fuser Sensor with a sheet of paper. Close the Drawer. The display changes from H to L.
YN
The display indicates a constant H.
YN
Go to Fl
ag 1 on BSD 10.
1 and check the harness for a short circuit. If the harness is
good, replace the Pre Fuser Sensor (PL 7.10).
Open the Drawer (the paper should still be blocking
the sensor). Connect the meter from
P/J420-A11 on the IOT Drive PWB to GND. Close the drawer. The voltage at P/J420-
A1
1 goes from +5 VDC when the drawer is open, to less than +1.0 VDC when the
drawer is closed.
YN
There is +5 VDC between P
/J420
-A12 and P/J420-A10 on the IOT Drive PWB.
YN
Go to Fl
ag 2 on B
SD 10.1 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 10.1 and check the harness for an open circuit. If
the harness is good, replace the Pre Fuser Sensor (PL 7.10). If the problem contin-
ues, replace the IOT Drive PWB (PL
9.2).
Replace t
he IOT Drive PWB (PL 9.2).
Check
/replace the following components until the problem is resolved. Replace any compo-
nents that are worn, broken, binding, or slipping:
• Drives for the 2nd BTR Roll (P
L 7.10)
•
2nd BTR Roll (PL 7.10)
•Guide (PL 7.
10)
10-103 Pre Fuser Sensor On RAP
The Pre Fuser Sensor detected paper when closing the Front Cover or when power was
switched on.
Initial Actions
Refer to BSD 10.1 and 10.12 for the following procedure.
Check the following:
• Check for paper on the Pre Fuser Sensor
• Clean the Pre Fuser Sensor
• Ensure that connectors P/
J420 and
P/J157 are seated correctly on the IOT Drive PWB
and the Pre Fuser Sensor, and there are no obvious crimped or broken wires.
• Ensure the Front Cover is closed. Switch the power Off then On.
Procedure
Enter dC330 010-100 Pre Fuser Sensor. Press Start. The display indicates H.
YN
Go to F
lag 1 on BSD 10.1 and check the harness for a short circuit. If the harness is good,
replace t
he Pre Fuser Sensor (PL 7.10).
If the fault code is present and can not be cleared, replace the IOT Drive PWB (PL 9.2)
. If the
fault code is not present and is occurring intermittently, go to Flag 1 on BSD 10.1 and check the
harness for an intermittent short circuit. If the harness is OK, replace the Pre Fuser Sensor (PL
7.10). If the problem continues, replace the IOT Drive PWB (PL 9.2).
