Common causes

  • 1Adhesive residue on sensor lens.
  • 2Misaligned media path.
  • 3Incorrect label media type.
  • 4Sensor calibration mismatch.

Solutions

Quick Diagnostics

The E-202 alert happens when the optics fail to register label boundaries. Ensure the media is seated correctly.

Step-by-step Solution

  1. Open compartment: Access the label bay.
  2. Clean sensor: Dust the sensor lens carefully.
  3. Calibrate: Perform a full calibration reset.

Prevention and Maintenance

Regularly wipe the optics after every few rolls to prevent residue buildup.

When to call a technician

If calibration fails, the internal optical sensor may need replacement.
