Scanner Maintenance This section gives you basic maintenance instructions and tells you how to transport your scanner safely. Cleaning the Scanner 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 that is free of lint. Paper towels are not recommended for cleaning the glass. 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. 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. Never open the scanner case. Don't spray lubricants inside the scanner. If you think repairs or adjustments are necessary, consult your dealer or contact EPSON. 41

Cleaning the Scanner
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 that is free of lint.
Paper towels are not recommended for cleaning the glass. 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.
Never use a harsh or abrasive brush or cleaning product to clean
the document table. A damaged glass surface can decrease the scanning
quality.
