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.
