Common causes

  • 1Fuser thermistor failure causing temperature readings to fail.
  • 2Heating lamp exhaustion in the fuser assembly.
  • 3Internal rollers seized due to severe paper jam residue.
  • 4Damaged power circuit supplying the fuser assembly.

Solutions

Diagnóstico rápido

This error is often accompanied by a burning smell or physical signs of paper jamming near the back of the unit. It signifies a failure in the fuser's heating circuit or thermistor feedback system.

Solución paso a paso

  1. Cool down period: Power off the unit immediately and allow it to cool down for at least 20 minutes.
  2. Inspect the fuser: Open the rear access door and check for any paper debris obstructing the fusing rollers.
  3. Safety restart: Plug the device into a dedicated wall outlet, skipping any surge strips to rule out power issues.

Prevención y mantenimiento

Prevent fuser wear by avoiding excessive power cycling (turning it on and off). If you see smeared toner on pages, perform a cleaning cycle if available to keep the fuser rollers debris-free.

Cuándo llamar a un técnico

If the error persists after a cool-down and restart, the fuser heating element has likely reached its end-of-life and needs professional replacement.

Frequently asked questions

This is a temperature-related alert for the fuser unit, suggesting it is either failing to heat up or has overheated.

Do not attempt to print, as you risk damaging the fuser unit further or causing internal printer damage.

No, this is a mechanical temperature issue with the fuser, entirely independent of the toner cartridge.

Avoid heavy, non-stop print jobs and use only recommended paper weight to reduce mechanical stress.
