Solutions

Diagnóstico rápido

The error usually appears with an audible warning beep and a 'Paper Jam' message on the display. Identify if the paper is visible by removing Tray 1 or if it is stuck in the fuser area behind the rear door.

Solución paso a paso

  1. Remove Tray 1 completely and check for wrinkled sheets blocking the feed path.
  2. Open the rear door and visually inspect if paper is trapped near the fuser (heating section).
  3. Remove the paper with both hands by gently pulling in the direction of the feed path, avoiding tearing.
  4. Check the rollers to ensure there are no paper fragments or accumulated toner dust.
  5. Close all compartments and restart the machine.

Prevención y mantenimiento

Always fan the paper before loading it into the tray to separate the sheets and prevent sticking due to humidity. Do not exceed the maximum tray capacity (550 sheets max total depending on config). Clean the feed rollers with a cloth slightly dampened with distilled water every 3 months.

Cuándo llamar a un técnico

If jams are frequent even with fresh paper, the pick-up roller may be worn, or a presence sensor might be damaged. Professional technical intervention is required for part replacement.
