Lexmark mx822adxe error 80.02: Fan Failure

The Lexmark mx822adxe error 80.02 is a cooling system code indicating that an internal fan is not operating according to RPM specifications. The thermal management system shuts down the printer preventively to prevent accumulated heat from ruining the mainboard or the fuser during high-load operations.

Common causes

  • 1Dense dust accumulation blocking fan rotation.
  • 2External obstruction (cables, papers, walls) of airflow.
  • 3Fan motor bearing dry or mechanically locked.
  • 4Failure of the fan speed sensing circuit on the mainboard.

Solutions

Diagnóstico rápido

Why does my Lexmark mx822adxe show error 80.02? The fan speed sensor reports a failure (blockage or burnt motor). Check if the cooling vents are obstructed by cables or nearby furniture preventing air intake.

Solución paso a paso

  1. Turn off the printer and disconnect it from power completely.
  2. Visually verify there are no cables, clothing, or paper blocking the side ventilation slots.
  3. Use compressed air on the side grilles to release dust accumulated on the blades.
  4. If the machine has been in a very hot environment, move it to an area with better air circulation.

Prevención y mantenimiento

Maintain at least 15-20 cm of clearance between the printer and any wall or furniture. Vacuum the cooling grilles monthly to prevent dust from entering the circuits.

Cuándo llamar a un técnico

If after cleaning the dust and clearing the area the error 80.02 continues to appear, the fan motor is burnt or the bearing is seized, requiring physical replacement.

Frequently asked questions

This error means the mainboard detects that one of the internal fans is not spinning at the correct RPM.

No, it is a safety measure; continuing without cooling will cause motherboard damage due to heat.

No consumables are required, but regular internal cleaning is vital for machine longevity.

If the error persists after cleaning the vents, the fan bearing is likely worn out.
