The error 04 manifests when the printer's media sensor fails to see the gaps or black marks on the label stock. If the machine stops with a steady beep, verify the labels are loaded correctly in the print path.

Solución paso a paso

  1. Power down the printer and disconnect it from the power source.
  2. Open the print head and remove the label roll to access the sensor area.
  3. Clean the media sensor path using a clean, dry cloth or compressed air to remove adhesive dust.
  4. Reload the media, ensuring it sits correctly within the guide markers.
  5. Calibrate the device via the menu settings to refresh sensor readings.

Prevención y mantenimiento

Clean the media sensor assembly every time you replace label rolls. Keeping the print path free of dust and adhesive buildup ensures long-term reliability and accurate media detection.

Cuándo llamar a un técnico

If the error 04 persists after multiple calibration attempts, the physical sensor might be faulty and require professional replacement.
