  • 4Wear on fuser unit rollers.

Solutions

Diagnóstico rápido

The C-4401 error usually occurs upon startup or when commencing a print job, displaying a critical failure message. The printer stops all mechanical operation to prevent potential fires or further internal damage caused by thermal faults.

Solución paso a paso

  1. Cool Down: Switch off the device and let it cool for at least 20 minutes.
  2. Cleaning: Open the rear door and check for any paper remnants blocking the fuser rollers.
  3. Power Source: Ensure the printer is plugged into a wall outlet, avoiding power strips that might limit voltage flow.
  4. Reset: Restart the printer; if the error reappears immediately, the thermal sensor is likely failing.

Prevención y mantenimiento

Avoid using unsupported paper types that could stress the fuser. Internal cleaning every 50,000 pages helps reduce dust buildup on thermal sensors. Always use genuine toner to ensure proper adhesion at the standard heat settings.

Cuándo llamar a un técnico

If the error C-4401 remains after a physical inspection, the fuser or the thermistor requires professional replacement. These components operate at extreme temperatures and require certified maintenance.
