Solutions

Quick Diagnosis

If this error appears after long print runs, the head may be overheating. Check if the print head surface is dirty or if the label path has any adhesive accumulation causing extra drag.

Step-by-Step Solution

  1. Turn off power.
  2. Clean the print head surface carefully.
  3. Check cables for visible damage or oxidation.
  4. Power up; if fault persists, the print head is damaged.

Prevention and Maintenance

Always keep the print head clean to prevent hot spots. Replace ribbons before they wear out to protect the surface.

When to Call a Technician
