Solutions

Quick Diagnosis

If the printer refuses to load labels even after loading a new roll, the sensor is likely obscured. Check the optical sensor situated near the print head path. If it looks shiny or sticky, clean it to fix the issue.

Step-by-Step Solution

  1. Power Down: Open the paper cover.
  2. Remove Stock: Take out the roll for full sensor access.
  3. Cleaning: Wipe the sensor with a dry cloth or use an air duster.
  4. Test: Reload the label roll and feed again.

Prevention and Maintenance

Use high-quality label stock to prevent excessive adhesive runoff. A quick check of the sensors at every roll change will ensure long-term, trouble-free operation.

When to Call a Technician

If the sensor has been cleaned and the printer fails to register paper presence entirely, the internal sensor board may require replacement.
