Common causes

  • 1Extremely high 'Darkness' setting.
  • 2Long print runs without resting periods.
  • 3Obstructed fans or output vents.
  • 4High ambient operating temperature.

Solutions

Quick diagnosis

Error 04 stops the device abruptly to prevent the head from burning. Why is my printer showing thermal error 04? It occurs because of high darkness settings during long print runs without cooling pauses.

Step-by-step solution

  1. Turn off the unit and let the printhead rest for 15 minutes.
  2. Open the lid to facilitate heat dissipation.
  3. Reduce darkness in your printing software (set 'Darkness' between 5 and 10).
  4. Check vents to ensure they are not blocked by dust.

Prevention and maintenance

Implement pauses during high-volume print jobs. Keep the workspace clear to allow constant airflow. Never set darkness to maximum unless strictly necessary.

When to call a technician

If the error occurs immediately upon power-on after a long rest, the internal temperature sensor is likely faulty.
