Cleaning the Outside of the Scanner

Excessive dust accumulation around and on the scanner will pull into the scanner during the scanning process
and clog the ventilation openings. You should clean the outside of the scanner at least once a month to help limit
the amount of dust build up in the scanner.
Note: You will need the blower brush provided with your scanner and a soft dusting cloth to clean the scanner.
1. Turn off the scanner power.
2. Using the blower brush, brush away any dust build up around the ventilation openings.
3. Using a soft dusting cloth, wipe down the body of the scanner, input tray and exit area. Make sure that the
input and exit slots in the scanner are also clean.
4. If there is any accumulation of dust in the indentations around the buttons, use the blower brush to gently
brush away the dust.
5. When you're finished, press the power button to turn the scanner back on.
