Solutions

Diagnóstico rápido

If the light is blinking, the printer is effectively telling you: 'I cannot see where one label ends and the next begins.' Always check the media path first.

Solución paso a paso

  1. Ensure the label stock is properly centered.
  2. Initiate a manual media calibration by holding the feed button.
  3. The printer will cycle through a few labels; ensure the printhead is locked down.
  4. If it stabilizes at green, you are good to go.

Prevención y mantenimiento

Adhesive buildup on the sensor track is the #1 cause of this error. Clean this area with a dedicated cleaning pen every 2–3 rolls.

Cuándo llamar a un técnico

If the printer refuses to calibrate after cleaning, the optical sensor may have reached its end-of-life cycle.
