Solutions

Quick Diagnosis

If this error appears after long sessions of continuous printing, the equipment needs a break. If it is immediate, the thermistor might be giving an erroneous reading due to a short circuit.

Step-by-step Solution

  1. Technician rest: Power off the printer for 45 minutes in an area with good air circulation.
  2. Ventilation check: Ensure that the ventilation grilles are not pressed against a wall.
  3. Paper load: Ensure you are not using coated or thick paper not suitable for this model.

Prevention and Maintenance

Avoid printing files with 100% toner coverage uninterruptibly. Allow the printer to rest between heavy jobs.

When to call a technician

If the error persists after cooling the equipment and restarting, the internal thermistor is failing and requires replacement.
