Common causes

  • 1Sensor misalignment
  • 2Incorrect media type setting
  • 3Sensor contamination (dust/glue)
  • 4Labels too transparent for sensor

Solutions

Diagnóstico rápido

If the error appears after loading a new roll, the printer likely doesn't recognize the gap or reflective mark on the new label media.

Solución paso a paso

  1. Open the side cover and verify the media is perfectly aligned in the path.
  2. Access the LCD 'Setup' menu and run a 'Media Calibration'.
  3. Verify the media type (Gap vs. Mark) in the printer settings matches your labels.
  4. Clean the sensor path with isopropyl alcohol.

Prevención y mantenimiento

Calibrate the printer after every media change. Keep the printhead and sensor area free of adhesive residue for consistent results.

Cuándo llamar a un técnico

If calibration fails repeatedly, the internal light/reflective sensor might be failing and needs professional replacement.

Frequently asked questions

This error means the printer cannot detect label gaps or black marks, suggesting an incorrect sensor sensitivity setting.

No, printing is halted until the sensor confirms the start of a new label position.

Standard industrial thermal transfer ribbons (wax, resin, or wax/resin) are supported.

Regular cleaning of the sensor path using an alcohol swab prevents label residue buildup.
