  • 2Label media not properly aligned.
  • 3Incorrect sensor type selected in settings.
  • 4Hardware sensor failure.

Solutions

Diagnóstico rápido

If the printer enters an error state immediately upon loading new labels, it's a media sensor issue. Check that the label stock isn't blocking the sensor area.

Solución paso a paso

  1. Remove labels and clean the media sensor with alcohol.
  2. Realign the media so it covers the sensor path.
  3. Hold the feed button until the LED blinks for auto-calibration.
  4. Perform a test print to confirm the printer detects each label.

Prevención y mantenimiento

Clean sensors at every media change. Keep the printhead and platten roller free of adhesive buildup to ensure smooth movement.

Cuándo llamar a un técnico

If calibration fails repeatedly, the sensor may be misaligned or faulty and requires hardware inspection.
