Solutions

Diagnóstico rápido

The error 500 is commonly a friction issue. Check if the printer's feed rollers have become too smooth or coated in toner, as this prevents them from gripping paper successfully.

Solución paso a paso

  1. Check Tray: Ensure paper is correctly aligned and within the capacity limits.
  2. Clean Rollers: Gently wipe the feed rollers with a damp, lint-free cloth to restore grip.
  3. Fan Paper: Fan the paper stack to reduce static, which can cause multi-sheet feeding or jams.
  4. Inspect Sensors: Ensure the paper sensor lever moves freely and isn't stuck.

Prevención y mantenimiento

Clean rollers every 10,000 pages to maintain performance. Operating in a controlled humidity environment helps prevent static, which is a major cause of feed failure.

Cuándo llamar a un técnico

If the mechanism still fails after cleaning the rollers and verifying the paper path, the motor or solenoid for the pickup unit may require professional service.
