Solutions

Diagnóstico rápido

The err-01 code is often accompanied by a flashing red light. Ensure the media sensor is not covered by adhesive residue or paper scraps to confirm the diagnosis.

Solución paso a paso

  1. Power down: Turn off the printer and unplug the power cable for 30 seconds.
  2. Check media: Ensure the label roll is properly seated and not blocking the sensor path.
  3. Clean sensors: Use compressed air or a lint-free cloth to clean the media sensor.
  4. Calibrate: Restart the printer and perform an auto-calibration by holding the Feed button.

Prevención y mantenimiento

Keep the internal path free of debris. Use genuine labels to avoid adhesive buildup. Clean the sensor path periodically to prevent false errors.

Cuándo llamar a un técnico

If the sensor remains unresponsive after multiple calibration attempts, it may be a hardware defect requiring component replacement.
