Common causes

  • 1Adhesive residue on the sensor lens.
  • 2Misaligned paper roll.
  • 3Mismatched software labels size.
  • 4Sensor component failure.

Solutions

Quick Diagnosis

If the printer continuously feeds labels until reaching an error state, the gap sensor is failing to register the gap edges.

Step-by-step Solution

  1. Ensure the roll is centered properly.
  2. Clean the gap sensor with a soft cotton swab.
  3. Trigger the auto-calibration sequence from the device menu.
  4. Verify media settings in your software correspond to the installed label size.

Prevention and Maintenance

Use high-quality labels to avoid adhesive residue. Clean the sensor path as part of your maintenance schedule.

When to call a technician

If repeated cleaning and calibration do not fix the issue, the physical sensor may be malfunctioning.
