If your printer stops during a heavy job with this error, it is likely that the thermal sensors detected insufficient cooling airflow. Look for dust buildup at the rear vents.

Step-by-step Solution

  1. Turn off the printer.
  2. Disconnect from the power source for 15 minutes.
  3. Clear the ventilation areas with compressed air.
