Common causes

  • 1Excessive continuous printing.
  • 2High print density settings.
  • 3Contaminated printhead requiring extra power.
  • 4High ambient environmental temperature.

Solutions

Quick Diagnosis

If you have been printing large volumes, the thermal elements have reached their design limits for heat dissipation.

Step-by-step Solution

  1. Shut down the printer immediately.
  2. Open the printer cover to expose the head.
  3. Wipe the head clean with an alcohol pen to remove debris.
  4. Wait 15-20 minutes before resuming operation.

Prevention and Maintenance

Lower the 'Darkness' or 'Heat' settings in your driver if a perfect black print isn't mandatory. Use high-quality consumables.

When to call a technician

If the error appears instantly upon cold startup without printing, the temperature sensor is malfunctioning.
