Xerox AltaLink C8155 Error 010-320: Fuser Troubleshooting

The Xerox AltaLink C8155 error 010-320 signals a temperature fault in the fuser unit. Because the fuser is responsible for heat-pressing toner onto the page, a temperature deviation triggers a protective shutdown. The best approach is to allow the unit to cool down completely and check for physical paper jams or buildup in the output area.

Solutions

Diagnóstico rápido

The error 010-320 occurs when the fuser heater fails to reach target temperature or overheats. Why does my printer show error 010-320? It means the internal sensor is not reading expected data, signaling that the heating system is disabled to prevent fire or hardware damage.

Solución paso a paso

  1. Switch off the printer and disconnect power for at least 30 minutes.
  2. Check for jams in the fuser door to ensure no paper is insulating the heating elements.
  3. Power on and let the machine complete its self-test.
  4. If the error persists, the fuser needs a hard reset via technical mode or replacement.

Prevención y mantenimiento

Avoid printing on non-standard media like envelopes or thick stickers. Schedule professional fuser unit maintenance every 200,000 pages to avoid downtime.

Cuándo llamar a un técnico

If the error returns immediately after restarting, the fuser lamp or thermistor has failed, requiring a replacement of the entire fuser module.
