Solución paso a paso

  1. Release printhead: Open the lever.
  2. Check integrity: Replace the ribbon roll if broken.
  3. Thread correctly: Align ribbon over the printhead.
  4. Resume printing: Close lever and press pause/resume.

Prevención y mantenimiento

Use genuine ribbons. Generic or low-quality ribbons may not have the required opacity for the sensor to detect them accurately.

Cuándo llamar a un técnico

If the ribbon path is clear but the sensor is constantly triggered, the sensor assembly may require technical service.
