Diagnóstico rápido

E-02 signals a failure in the detection circuit. If the printer doesn't react after paper insertion, a sensor blockage is the primary suspect.

Solución paso a paso

  1. Open: Lift the printer cover.
  2. Clear: Use compressed air to clean the sensor notch.
  3. Reload: Ensure the paper is firmly against the rollers.
  4. Reset: Restart the unit.

Prevención y mantenimiento

Regularly clean the thermal head and sensor area. Always use high-quality thermal paper to minimize residue.

Cuándo llamar a un técnico

If mechanical sounds persist or the sensor fails after cleaning, the main board may be damaged.
