Common causes

  • 1Dust buildup on the sensor lens blocking the IR signal.
  • 2Label adhesive residue stuck to the print path due to label breaks.
  • 3Incorrect sensor type configured in the printer's ZPL settings.
  • 4Wear and tear on the internal sensor after long-term industrial use.

Solutions

Diagnóstico rápido

If your printer stops printing and displays error 002, the sensor is likely unable to detect the gap between labels. Ensure the media is properly threaded through the sensor path.

Solución paso a paso

  1. Release printhead: Lift the side pressure lever.
  2. Clean optical sensor: Gently clean the sensor area with alcohol.
  3. Re-thread label roll: Make sure labels are positioned firmly in the guide.
  4. Run calibration: Access the 'Calibration' mode on the control panel.

Prevención y mantenimiento

Keep the sensor path free of dust and adhesive residue. Using high-quality genuine Zebra labels ensures consistent sensor detection and prolongs printhead life.

Cuándo llamar a un técnico

If the calibration fails repeatedly after cleaning, the sensor hardware may be damaged and require professional replacement.

Frequently asked questions

This error appears when the media sensor cannot detect the label gap or black mark, usually due to dust or misalignment.

It is not a fatal hardware failure, but it stops the print queue. It requires manual intervention to resume operation.

It supports standard wax, wax/resin, and resin ribbons up to 450 meters in length.

We recommend cleaning the sensor path every time you switch label rolls to prevent build-up.
