Heat Roll Sts Fail Rap - Xerox VersaLink B7025 Service Manual

059-326 Heat Roll STS Fail RAP

BSD-ON: BSD 10.2 Fusing Heat Control (2 of 2)
059-326 The system detected an open circuit of the heat roll thermistor.
Initial Actions
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to GP 10. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
• Ensure that the fuser is installed correctly.
• Check the drawer connector between the fuser and the main unit ( DP612) for damage.
• Ensure P/J416 on the drive PWB is connected correctly.
Procedure
Remove the fuser. Measure the resistance between DJ612S pin 7 and pin 8 (across the heat
roll thermistor). An open circuit is measured.
Y N
Check the items that follow: connections for open circuits, short circuits or poor contacts:
• Between DJ612S pin 8 and P/J416
• Between DJ612S pin 7 and P/J416
If the wiring is good, install a new drive PWB,
Install a new fuser, PL 10.05 Item 2.

059-372 Heat Roll NC Sensor Differential Fail RAP
BSD-ON: BSD 10.2 Fusing Heat Control (2 of 2)
059-372 Abnormal temperature monitor AD value of the heat roll NC sensor was detected 10
consecutive times.
Procedure
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
death or injury. Moving parts can cause injury.
Perform the steps that follow:
1. Switch off, then switch on the machine,
2. Ensure that the fuser is installed correctly.
3. Check the drawer connector between the fuser and the main unit ( DP612) for damage.
4. Check the connections and wiring between the fuser ( DP612) and the drive PWB (
J416) for an open circuit, short circuit or poor contact.
5. If the fault persists, install new components as necessary:
• Fuser, PL 10.05 Item
• Drive PWB, PL 1.10 Item
6. After correcting the fault, reset the value of NVM location 744-003 (Differential Amplifica-
tion Error Detection Flag) to 0 (Normal). Switch off, then switch on the machine,
