Solutions

Diagnóstico rápido

The error W-01 is identified by a clear text prompt on the printer display. If you hear grinding noises or a sudden stop during printing, it is likely that a paper jam is causing the error. Inspect the paper path to confirm no debris remains.

Solución paso a paso

  1. Disconnect the power cable to prevent the print head from moving unexpectedly.
  2. Open the scanner unit and front cover and use a flashlight to locate any stuck paper inside the print area.
  3. Gently pull out the paper in the direction of the paper flow; avoid jerky movements to prevent tearing the paper inside the machine.
  4. Check the rear feeder for any crumpled pages and ensure the paper guides are flush against the stack.

Prevención y mantenimiento

To keep your printer efficient, always use standard weight paper and ensure the stack is perfectly flat. Clean the internal rubber feed rollers using a lint-free cloth periodically. Using genuine ink bottles prevents clogs and maintains proper internal pressure.
