Epson expression 1640xl 用户手册

To keep your scanner operating at its best, you should clean it periodically. Before 
cleaning, unplug the power cord.

Use a soft cloth to clean the outer case with mild detergent dissolved in water.

If the document table glass gets dirty, clean it with a soft, dry cloth. If the glass is 
stained with grease or other hard-to-remove material, use a small amount of glass 
cleaner on a soft cloth to remove it. Wipe off any remaining liquid with a dry cloth.

Be sure there’s no dust on your document table. Dust can cause white spots to appear 
in your scanned image.

Always unplug the scanner before cleaning.

Never use a harsh or abrasive brush or cleaning product to 
clean the document table. A damaged glass surface can 
decrease the scanning quality.

Never use alcohol, thinner, or corrosive solvent to clean the 
scanner. These chemicals can damage the scanner 
components as well as the case.

Be careful not to spill liquid into the scanner mechanism or 
electronic components. This could permanently damage them.

Don’t spray lubricants inside the scanner.

Never open the scanner case. If you think repairs or 
adjustments are necessary, consult your dealer or contact 
EPSON.

Unplug the scanner and refer servicing to qualified service 
personnel if the power cord or plug is damaged, if liquid has 
entered the scanner, if the scanner has been dropped or the 
case damaged, or if the scanner does not operate normally or 
exhibits a distinct change in performance.
