10-107 Fuser Exit Sensor On RAP
The Fuser Exit Sensor detected paper when closing the Front Cover or when power was
switched on.
Initial Actions
Refer to BSD 10.7 and 10.12 for the following procedure.
Check for the following:
•
Check for paper on the Fuser Exit Sensor.
• Clean the Fuser Exit Sensor
• Ensure that connectors P/J413A 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.
• Ensure the Front Cover is closed. Switch the power Off then On.
Procedure
Enter dC330 010-105 Fuser Exit Sensor . Press Start. The display indicates H.
Y N
Go to Flag 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 ).
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 10.7 and check the
harness for an intermittent short circuit. If the harness is OK, replace the Fuser Exit Sensor ( PL
8.10 ). If the problem continues, replace the IOT Drive PWB ( PL 9.2 ).
10-110 Machine Exit Sensor On Jam RAP
The Machine Exit Sensor did not actuate within the specified time after the Fuser Exit Sensor
actuated.
Initial Actions
Refer to BSD 10.7, 10.9, and 10.12 for the following procedure.
Check for the following:
•
Obstructions in the paper path or damage on lead edge of sheets
• Contamination on the Fuser Exit Roll and/or M/C Exit Roll.
• Ensure that connectors P/J412B , P/J418B , and P/J149 are seated correctly on the IOT
Drive PWB and the Machine Exit Sensor, and there are no obvious crimped or broken
wires.
• Open the Inverter Door ( PL 2.23 ) and clean the Machine Exit Sensor. Also, ensure that
the sensor actuator is not bent or damaged; that it does not contact the harness or baffles;
and that it is seated in the bracket correctly.
• Clean the Fuser Exit Sensor.
• Cheat the Front Door Interlock and observe the paper as it feeds out of the Fuser Exit
Assembly and into the Inverter Top Chute Assembly. Ensure that the lead edge is not
catching on the baffles or cutouts.
Procedure
Enter dC330 010-110 Machine Exit Sensor . Press Start . Actuate the Machine Exit Sensor
actuator. The display changes from L to H.
Y N
The display is a constant H.
Y
N
Go to Flag 7 on BSD 10.7 and check the harness for an short circuit. If the harness is
good, replace the Machine Exit Sensor ( PL 2.25 ).
Connect the meter from P/J412B -5 on the IOT Drive PWB to GND. Actuate the Machine
Exit Sensor actuator. The voltage at P/J412B -5 goes from less than +1.0 VDC when
the sensor is deactuated, to +5 VDC when the sensor is actuated.
Y
N
There is +5 VDC between
P/J412B -6 and P/J412B -4 on the IOT Drive PWB.
Y N
Go to Flag 8 on BSD 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 7 and Flag 8 on BSD 10.7 and check the harness for an open circuit. If
the harness is good, replace the Machine Exit Sensor ( PL 2.25 ). If the problem con-
tinues, replace the IOT Drive PWB ( PL 9.2 ).
Replace the IOT Drive PWB ( PL 9.2 ).
Enter dC330 010-105 Fuser Exit Sensor. P ress Start. Block the Fuser Exit Sensor with a
sheet of paper. The display changes from H to L.
