Solutions

Quick Diagnosis

The device stops and shows the Label Not Detected message on the screen. Check if the paper has been loaded correctly over the lower sensor's white guide.

Step-by-Step Solution

  1. Alignment: Ensure the sensor is positioned under the label area.
  2. Calibration: Access the configuration menu and run 'Sensor Calibration'.
  3. Load: Re-insert the media ensuring it passes through the sensor guide.

Prevention and Maintenance

Clean the sensors of paper dust after every label roll change. Use consumables that meet the specified transparency requirements.

When to Call a Technician

If the sensor does not detect the material even after calibrating, the LED emitter may have reached its end of life.
