Solutions

Diagnóstico rápido

If the machine showed poor print quality before displaying C450, the cartridge is likely nearing empty or experiencing a feed blockage. Confirm the supply levels in the machine menu.

Solución paso a paso

  1. Check toner: Ensure the toner cartridge is seated correctly and not locked.
  2. Shake cartridge: Remove the cartridge and shake it gently to loosen the toner inside.
  3. Clean sensor: Wipe the toner sensor window with a clean, dry cloth.
  4. Reboot: Close the cover and reboot to let the sensor read the toner levels.

Prevención y mantenimiento

Use original consumables only. Generic toner powder can have different viscosity, leading to clogs in the piping that trigger the C450 code.

Cuándo llamar a un técnico

If the error persists after checking the cartridge, the automatic toner feed pump may have seized and will require a service technician.
