Solutions

Diagnóstico rápido

The error 310 usually targets a specific tray. If the screen specifies "Tray 1" or "Tray 2", ensure the tray is fully seated. Loose paper sheets or scraps caught in the entrance sensor are the most frequent causes for this notification.

Solución paso a paso

  1. Pull out the paper tray causing the error.
  2. Empty the paper stack.
  3. Check inside the tray bay for any torn paper debris.
  4. Re-stack the paper neatly and adjust the side guides so they make light contact with the paper edges.
  5. Reinsert the tray and resume the print job.

Prevención y mantenimiento

Do not exceed the tray's maximum paper capacity. Overfilling causes the pick-up rollers to slip, leading to feeding errors. Periodically clean the rubber pick-up rollers with a lint-free cloth dampened with distilled water to remove paper dust accumulation.

Cuándo llamar a un técnico

If the error 310 persists despite fresh paper and cleaned rollers, there may be a hardware fault in the tray's paper-sensing unit or the feed motor.
