Common causes

  • 1Heater lamp failure within the fuser assembly.
  • 2Poor electrical connection between fuser and chassis.
  • 3Thermistor failure causing false 'too cold' readings.
  • 4High humidity affecting the fuser heat retention.

Solutions

Quick Diagnosis

This error presents when the engine control board receives a signal that the fuser is too cold for printing. Look for the code immediately upon turning on the machine after a cold start.

Step-by-Step Solution

  1. Force Shutdown: Power off the printer using the main switch and disconnect the power cord from the wall for 20 minutes.
  2. Fuser Unit Removal: Release the safety locks to slide out the fuser unit and inspect it for fused toner residue or debris.
  3. Reinstallation: Slide the fuser back into the printer, ensuring electrical contacts are properly seated before turning it back on.

Prevention and Maintenance

Avoid printing on heavy stock materials excessively as they draw more heat from the unit. Use only original consumables and perform a quick air-dusting of the paper path during every second toner change.

When to Call a Technician

If the reset does not fix the error, it points to a physical failure of the heater bulb or the temperature sensor, which requires a certified technician to replace.
