Switch off the power. Cheat the Front Door Interlock Switch. Disconnect
Drive PWB. Check the resistance between J413 -13 and J413- A7 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.
Y N
Disconnect P/J171 on the Heat Roll Control Thermistor. The resistance should be in the
range of 0.78K ohms when the Heat Roll is hot, to 150K ohms when cool (room tempera-
ture). The resistance is within specification.
Y N
Replace the Heat Roll Control Thermistor
Go to Flag 1 and Flag 3 of BSD 10.2. Check for a loose wire or connector, or an intermit-
tent short circuit to ground.
Check the following:
• Check the H/R Control Thermistor for cleanliness, damage and excessive wear at the
point where the Thermistor contacts the Heat Roll. Ensure that it is installed correctly.
• If the surface of the Thermistor is worn, replace the H/R Control Thermistor
• Inspect the surface of the Heat Roll for excessive wear due to the Thermistor. Replace the
Heat Roll if necessary (PL 8.3).
If the problem continues, replace the H/R Control Thermistor
replace the IOT Drive PWB (PL 9.2).
