Solutions

Quick Diagnosis

If the status light turns solid or flashes to indicate high temperature, the printhead needs cooling. Verify the ambient room temperature is within specifications.

Step-by-step Solution

  1. Pause printing immediately.
  2. Power down the printer to let it cool naturally for 15+ minutes.
  3. Lower the Darkness setting via the printer driver.
  4. Inspect the printhead for debris that causes extra drag and heat.

Prevention and Maintenance

Use correct label settings for your stock. Keep the area ventilated and clean the printhead with alcohol wipes to reduce the work-load for the print elements.

When to call a technician

Persistent overheat errors despite cooling imply a faulty sensor board inside the print mechanism.
