Solutions

Diagnóstico rápido

If the fan is stationary or makes grinding sounds upon startup, the issue is mechanical. Error E805 prevents work to avoid internal overheating.

Solución paso a paso

  1. Power off: Turn off the printer and unplug from power.
  2. Clean vents: Remove dust accumulation from external ventilation grids using a vacuum.
  3. Check airflow: Ensure no obstacles block the airflow around the machine.
  4. Reset: Power back on to see if the fan status returns to normal.

Prevención y mantenimiento

Maintain at least 10 cm of clearance on all sides of the printer. Dust accumulation inside cooling vents is the primary cause of this error; keeping the area clean is essential.

Cuándo llamar a un técnico

If the error code E805 remains after external cleaning, an internal cooling fan may have failed and will need replacement by a service technician.
