a clean, soft cloth with water and wring the cloth well. Use the
well-wrung cloth to gently remove dirt and dust. Then,
thoroughly remove any moisture or water vapor with a soft,
dry cloth. Be particularly careful to remove any traces of dirt or
liquid when wiping the document glass.
• Moisture left on the document glass or cover may damage photographs and other
documents as well as produce poor results.
• Do not dampen the connectors, ports or other metallic components on the scanner’s
back panel. Immediately remove any moisture that contacts these components by
wiping them with a dry cloth.

Any moisture that enters the interior, the underside of the document glass or the
sensors may degrade image quality and lead to malfunctions.

Use of these substances may deform, discolor or dissolve the casing.
