Over Temperature Fail Rap - Xerox VersaLink B7025 Service Manual

010-331, 010-333 Over Temperature Fail RAP

BSD-ON: BSD 10.2 Fusing Heat Control (2 of 2)
010-331 Fuser thermistor detected temperature monitor AD value that is the specified value or
more 10 consecutive times.
010-333 Fuser NC sensor detected a temperature that is the specified value or more 10 con-
secutive times.
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.
• Remove the fuser. Check whether foreign substances or paper is wound around the heat
roll.
• Ensure J416 on the drive PWB is securely connected.
Procedure
Perform the steps that follow:
1. Install new components as necessary:
• LVPS, PL 1.10 Item 8.
• Fuser, PL 10.05 Item 2.
• Drive PWB, PL 1.10 Item 3.
• ESS PWB, PL 3.10 Item 6.
2. To clear this fault, first remove the cause, then reset the value of NVM location 744-002
(Error Detection Flag) to 0. Switch off, then switch on the machine,
NOTE: The relationship between the displayed value and the sensor that detected the high
temperature error is as follows:
• 0: Normal.
• 1: High temperature error of heat roll nc sensor.
• 2: High temperature error of heat roll thermistor.
• 3: Abnormal temperature increase of heat roll NC sensor, heat roll thermistor.
• 4: Hardware high temperature error of heat roll thermistor.

WARNING
GP 10.
010-332, 010-379 Heat Roll NC Sensor Fail RAP
BSD-ON: BSD 10.2 Fusing Heat Control (2 of 2)
010-332 Fuser NC Sensor compensation AD value or detection AD value was 1020 or more 10
consecutive times.
010-379 The time taken to recover from a high temperature not ready state has exceeded the
specified time.
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
• ESS PWB, PL 3.10 Item
