Solutions

Diagnóstico rápido

If the error occurs after heavy print cycles, the cooling system may be saturated. Check if the screen allows a restart after cooling the device.

Solución paso a paso

  1. Power off the unit completely and let it cool for at least 20 minutes.
  2. Clean the outer air vents to ensure proper airflow.
  3. Check the fuser rollers for debris causing increased friction.
  4. Restart the system. If C450 remains, the thermistor may be reporting false data.

Prevención y mantenimiento

Prevent C450 by leaving space around the printer for ventilation. Yearly technical maintenance is necessary to clean toner residue that impacts fuser temperature.

Cuándo llamar a un técnico

If the error persists after a full cool-down, a technician must inspect the temperature control thermistor.
