Solutions

Diagnóstico rápido

The 'Ribbon Out' message usually means the ribbon sensor is not receiving a signal from the film. Check if the film is loose or if it has snapped, preventing the take-up spindle from turning.

Solución paso a paso

  1. Check Ribbon: Ensure the ribbon is properly tensioned and routed.
  2. Clean Sensor: Gently wipe the optical ribbon sensor using an isopropyl alcohol swab.
  3. Calibrate: Perform a media/ribbon calibration through the printer's main menu.
  4. Print Mode: Confirm the printer is set to 'Thermal Transfer' mode rather than 'Direct Thermal'.

Prevención y mantenimiento

Regularly clean the printhead and sensor area to ensure clear readings. Using high-quality genuine Zebra ribbons will extend the life of the sensor optics and improve print quality.

Cuándo llamar a un técnico

If the error persists after thorough cleaning and calibration, the internal ribbon sensor may be physically failing and requires technical support.
