Cleaning Procedures
1. Power off the scanner and disconnect the power
cord.
2. Gently wipe the scan window glass with a soft
lint-free cloth and mild liquid detergent to remove
fingerprints, smudges, or loose particles. Do not
use a spray detergent as this may get inside the
case and damage the unit’s internal components.
3. Wipe off the detergent with a soft cloth damp with
water.
4. Finally, dry the surface by wiping it with a clean
soft cloth.
