Diagnóstico rápido

This error implies the thermistor detected an excessive heat spike, distinct from a general failure. Check if the environment temperature is within 25°C.

Solución paso a paso

  1. Shutdown the printer completely.
  2. Ensure all external and internal ventilation ducts are clear of lint.
  3. Allow at least 45 minutes for the fuser to dissipate heat.
  4. Restart the machine.

Prevención y mantenimiento

Schedule monthly cleaning for the air intake filters. Ensure the printer room has dedicated climate control to manage high-volume heat output.

Cuándo llamar a un técnico

If the SC544-01 continues to show after a cold boot, the fuser thermistor likely needs testing or replacement by a service engineer.
