Xerox B305 error 010-397: Fuser Fault Solution

The Xerox B305 error 010-397 relates to a thermal anomaly detected in the fuser. This happens when the thermal sensor registers a temperature that does not match what is expected for the current print mode. If you want to know what is error 010-397 on my Xerox B305, think of it as a protection against a possible short circuit or lack of heat.

Common causes

  • 1Fuser thermal sensor (thermistor) failure.
  • 2Heating element with material degradation.
  • 3Lack of adequate ventilation causing residual overheating.
  • 4Power supply faults in the circuit feeding the fuser.

Solutions

Quick Diagnosis

If the error occurs constantly after powering on the machine, the fuser cannot regulate itself. Listen to see if the cooling fan is running constantly.

Step-by-Step Solution

  1. Turn off the machine completely and disconnect from the power grid.
  2. Inspect the fuser compartment in the back for any foreign objects.
  3. Verify that the ventilation holes are free of dust.
  4. Power on and verify the behavior during the first minutes of preheating.

Preventive Maintenance

Perform periodic ventilation cleaning and keep the printer away from external heat sources so the thermostat operates precisely.

When to call a technician

If the error persists, the fuser module has exceeded its lifespan and requires professional technical replacement.

Steps to follow

  1. 1

    Power cycle

    Turn off the equipment and disconnect the power cable for about 10 minutes to cool the system.

  2. 2

    Fuser inspection

    Check that there is no paper blocking the output and no debris in the fuser.

  3. 3

    System reboot

    Turn the equipment on and check if the code disappears; otherwise, the fuser is faulty.

Frequently asked questions

It is a fuser temperature control fault warning, often detected as an inconsistency in heating.

Yes, the fuser is essential for printing. If the error doesn't clear, you won't be able to print or copy documents.

It is recommended to use original Xerox B305 series toner to not compromise the roller thermal cycle.

Use dry paper and ensure the printer has good ventilation at the rear.
