2.
Dampen a clean, soft cloth with water and wring
the cloth well. Use the well-wrung cloth to gently
remove dirt and dust. Be particularly careful to
remove any traces of dirt or liquid from the
document glass by wiping it with a dry soft cloth.
• 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.
• Do not use a sodden cloth or apply a liquid directly to any portion
of the scanner. Any moisture that enters the interior, the underside
of the document glass or the sensors may degrade image quality
and lead to malfunctions.
• Never use substances containing alcohol, thinners or benzene on
the equipment. Use of these substances may deform, discolor or
dissolve the casing.
