Common causes

  • 1Empty thermal paper roll.
  • 2Obstructed optical sensor due to paper dust accumulation.
  • 3Misaligned roll holder blocking the paper path.
  • 4Damaged cover sensor switch preventing proper registration.

Solutions

Diagnóstico rápido

This error occurs when the printer stops printing and the LED indicator signals a failure. If the roll is not empty, the issue is almost certainly a blocked optical sensor or a misaligned paper spool.

Solución paso a paso

  1. Check inventory: Confirm if the thermal paper roll is empty.
  2. Reload media: Properly insert the paper, ensuring the thermal side is oriented toward the printhead.
  3. Sensor cleanup: Use a brush or compressed air to remove paper particles from the central optical sensor.
  4. Reset: Securely close the printer cover and resume operation.

Prevención y mantenimiento

Choose high-quality thermal paper to minimize paper dust generation. Regularly vacuum or wipe the paper feed compartment to ensure sensors remain clear. Always store thermal paper in cool, dry conditions.

Cuándo llamar a un técnico

If the e-paper-out alert remains constant despite loading new paper and cleaning the compartment, there may be a permanent failure in the sensor assembly, necessitating professional repair.

Frequently asked questions

This error means the system does not detect any paper in the loading mechanism, often due to an empty roll or dust blocking the sensor.

Yes, paper dust buildup can obscure the sensor, causing it to incorrectly register an empty state.

The model uses standard 58mm width thermal rolls.

Use compressed air or a dry cloth to gently clear the paper compartment of debris.
