Common causes

  • 1Media path not aligned with sensor.
  • 2Adhesive buildup on the sensor lens.
  • 3Incorrect sensor type selection in settings.
  • 4Platen roller wear preventing proper media tension.

Solutions

Diagnóstico rápido

This error occurs when the printer fails to register the transition between labels. Check if your label gap aligns with the optical sensor inside the printer printhead assembly.

Solución paso a paso

  1. Clear any path obstructions in the label feed area.
  2. Slide the movable sensor to align with the gap on your labels.
  3. Reload the labels and close the printhead securely.
  4. Calibrate the sensor via the settings menu to teach the printer the new media size.

Prevención y mantenimiento

Perform regular cleaning of the platen roller. Adhesive residue from labels is the number one cause of sensor errors and feed slippage.

Cuándo llamar a un técnico

If the printer fails calibration repeatedly after sensor cleaning, the sensor assembly may require professional replacement.

Steps to follow

  1. 1

    Load media correctly

    Center the media roll on the spindle and ensure it follows the correct path.

  2. 2

    Align sensors

    Ensure the movable sensor is positioned over the label gap.

  3. 3

    Calibrate sensors

    Run the auto-calibration cycle from the settings menu to detect media length.

Frequently asked questions

The printer is failing to detect the label gaps or black marks through its sensors.

It is operationally critical as it prevents the machine from printing any further labels.

The printer supports standard thermal paper or synthetic labels compatible with transmissive or reflective sensors.

Clean the platen roller periodically to prevent adhesive buildup from causing slipping or errors.
