Solutions

Diagnóstico rápido

If you hear grinding sounds or the printer stops mid-cycle, the cleaning web or roller is failing to advance. This is almost always related to the fuser unit's cleaning cycle.

Solución paso a paso

  1. Power off: Shut down the printer and unplug it.
  2. Inspect fuser: Access the rear fuser door and carefully check for paper residue.
  3. Clear blockage: Gently remove any debris using tweezers or hands if safe.
