Drive PWB. Check the resistance between J413- A13 and J413-A9 of the harness. The resis-
tance should be in the range of 0.78K ohms when the Heat Roll is hot, to 150K ohms when
cool (room temperature). The resistance is within specification.

of BSD 10.2. Check for a loose wire or connector, or an intermit-
tent short circuit to ground.
Check the following:
•
Check the P/R Control Thermistor for cleanliness, damage and excessive wear at the
point where the Thermistor contacts the Pressure Roll. Ensure that it is installed correctly.
•
If the surface of the Thermistor is worn, replace the P/R Control Thermistor
•
Inspect the surface of the Pressure Roll for excessive wear due to the Thermistor.
Replace the Pressure Roll if necessary
If the problem continues, replace the P/R Control Thermistor
