•Remove any dirt particles with a soft, lint-free cloth lightly dampened with water.

•Gently wipe the window using a lens tissue moistened with ammonia/water.

•Do not spray water or other cleaning liquids directly onto the scanner or window.

•If the scan window becomes scratched, broken or contaminated with heavy dust, replace with a new window, which is available as an orderable accessory.
