Solutions

Diagnóstico rápido

If the C-2558 error appears, the machine suspects that the toner bottle is not rotating or the supply motor is not receiving power. Check that the toner bottle is seated correctly and the worm screw has no blockages.

Solución paso a paso

  1. Open the front door and remove the TN-118 toner cartridge.
  2. Clean the toner sensor contacts with a dry cloth.
  3. Check that the bottle nozzle is not obstructed by dry toner residue.
  4. Manually rotate the toner unit gear to confirm it is not jammed.
  5. Reinstall the toner, ensuring the locking mechanism clicks.

Prevención y mantenimiento

Avoid low-quality generic toners; low-quality toner powder often clumps and blocks the feed gears. Perform internal dust cleaning with compressed air every 6 months.

Cuándo llamar a un técnico

If the sensor does not detect the bottle even with new toner, the control board or the toner magnetic sensor has failed.
