Common causes

  • 1Degraded thermostat losing thermal efficiency.
  • 2Unstable power supply performance.
  • 3Excessive use of heavy paper tiring the fuser.
  • 4Loose internal power connection.

Solutions

Diagnóstico rápido

This error typically occurs during long print jobs. If pages arrive with loose toner, it is a clear indicator of thermal instability.

Solución paso a paso

  1. Power cycle the printer to see if the sensor stabilizes.
  2. Check fuser cables for any loose connections.
  3. Check paper weight; using heavy media requires more heat and may fatigue the unit.
  4. Call support if the error occurs after more than 50 pages.

Prevención y mantenimiento

Avoid printing on heavy stock unless necessary. Perform monthly cleaning to prevent thermal over-stress.

Cuándo llamar a un técnico

Error 500-02 often indicates a degraded thermostat that needs professional replacement.
