  2. Inspect the internal path for crumpled sheets or tiny fragments.
  3. Align the paper guides to fit the paper snugly without over-tightening.
  4. Wipe the rubber rollers with a lint-free cloth dampened with distilled water.
  5. Reinsert the tray and ensure it locks into place.

Prevención y mantenimiento
