Heat Roll Nc Sensor Fail Rap - Xerox VersaLink B7025 Service Manual

010-334, 010-335 Heat Roll NC Sensor Fail RAP

BSD-ON: BSD 10.2 Fusing Heat Control (2 of 2)
010-334 Heat roll NC sensor temperature - heat roll thermistor temperature was detected at 90
(NVM) degrees or higher 10 consecutive times or more. Heat roll thermistor temperature - heat
roll NC sensor temperature was detected at 70 (NVM) degrees or higher 10 consecutive times
or more.
010-335 Fuser NC sensor compensation output AD value was detected below 130 degrees for
10 consecutive times or more. Fuser NC sensor detection output AD value was detected below
150 degrees for 10 consecutive times or more.
Procedure
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.
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 heat roll sensor ( P/J124) and the drive
PWB ( P/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 2.
• Drive PWB, PL 1.10 Item 3.
• ESS PWB, PL 3.10 Item 6.

010-337 Heat Roll Paper Winding RAP
BSD-ON: BSD 10.2 Fusing Heat Control (2 of 2)
010-337 From the value of the fuser thermistor and NC sensor, paper was wrapped around the
heat roll.
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. Remove any jammed paper from the fuser. Ensure the customer is using paper within
specification, GP 15.
2. If no jammed paper was found, install a new fuser,
3. Reset the value of NVM location 744-002 (Error Detection Flag) to 0. Switch off, then
switch on the machine, GP
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.
