Scanner Maintenance
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. 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.
When using the optional TPU, a transparent window in the scanner is used for
white calibration before each scan. Light from the TPU lamp is used as a
reference by the scanner head. Make sure to keep this area clean to prevent
colored vertical lines from appearing 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.
