Care and Maintenance
Dust or dirt accumulating on the clear plate of the scanning window will affect reading performance. If you use the
scanner in dusty areas, therefore, periodically check the clear plate of the scanning window and clean it if dusty.

To clean the plate, first blow the dust away with an airbrush. Then gently wipe the plate with a cotton swab or the
similar soft one.

If sand or hard particles have accumulated, never rub the plate; doing so will scratch or damage it. Blow the
particles away with an airbrush or a soft brush.
