Common causes

  • 1Fuser temperature sensor (thermistor) failure.
  • 2Deformed pressure roller affecting heating consistency.
  • 3Inadequate voltage supply to the fuser unit.
  • 4Component wear due to excessive duty cycle.

Solutions

Diagnóstico rápido

The error 010-320 is usually accompanied by physical signs, such as a hot smell or paper jams behind the fuser door. Do not ignore the alert, as further use could cause fire risks.

Solución paso a paso

  1. Power off the printer and wait 15 minutes for the fuser to cool.
  2. Open the rear door to check for any physical paper blockage.
  3. Ensure the printer is plugged directly into a wall outlet.
  4. If the error reoccurs on startup, the fuser assembly is faulty.

Prevención y mantenimiento

Use correct media thickness and avoid low-quality labels that can stick to the rollers. Regular office environment cleaning helps keep internal components cool.

Cuándo llamar a un técnico

If the fault persists upon rebooting (while the fuser is still cold), the heating element or thermistor is broken and needs professional replacement.

Frequently asked questions

It indicates an abnormal temperature in the fuser unit, often due to sensor or heating element failure.

Fusers operate at high heat. Shut down the printer safely to avoid component damage.

Use original Xerox B310 series toner to ensure compatibility and fuser protection.

Typically, the fuser assembly needs replacement if the sensors are non-responsive.
