Maintenance
Water or grime on the window of the scanner distorts the laser beam and impair
performance. Moving from one temperature extreme to another causes
condensation to form on the optical surfaces and also affects scanner
performance.
Follow these guidelines to maintain the scanner:
Clean the window with a cotton cloth and ammonia or water. Dry with a soft
cotton cloth or allow to air dry.
Do not use a dry tissue to wipe the window. This causes small scratches on
the window.
Do not immerse the unit in water.
Operate and store store in an environment with 0% to 95% relative humidity.
