Solutions

Diagnóstico rápido

The error W-01 indicates that the paper feed sensor isn't detecting media in the tray. If your printer displays this code, verify if the paper guides are locked against the stack.

Solución paso a paso

  1. Unplug the printer to ensure safety during inspection.
  2. Clear the path of any curled sheets, dust, or foreign objects in the tray.
  3. Wipe the rollers using a clean, soft cloth dampened slightly with distilled water.
  4. Power on and press the start button to re-initialize the feed mechanism.

Prevención y mantenimiento

Avoid overstuffing the paper tray beyond its 100-sheet limit. Regularly wipe the internal area of the printer to keep it free from dust buildup. Using high-quality, standard-weight paper minimizes the risk of frequent feed errors.

If the error persists after performing a thorough cleaning and manual inspection of the feed rollers, there may be a faulty internal gear or a sensor failure that requires a certified technician.
