Common causes

  • 1Debris on the optical lens.
  • 2Misaligned media blocking the sensor.
  • 3Incorrect sensor sensitivity settings.
  • 4Use of non-standard label gaps.

Solutions

Diagnóstico rápido

If the indicator light flashes orange or red, the printer cannot detect the label gap. This happens frequently after switching to a new label type.

Solución paso a paso

  1. Deep cleaning: Clean sensors with air duster and alcohol.
  2. Reloading: Remove and reload the roll through the guides.
  3. Calibration: Run media calibration via LCD panel.
  4. Media settings: Verify that the media type (Gap/Mark) is correctly configured.

Prevención y mantenimiento

Adhesive buildup on the sensor is the most common failure point. Clean the guides regularly. Always use certified consumables.

Cuándo llamar a un técnico

If the sensor remains unresponsive after cleaning and calibration, the internal optical module may be faulty.
