subject to vibration.
● Avoid exposing the scanner to rapid
changes in temperature. If the room
in which the scanner is installed is
cold but rapidly heated, water
droplets (condensation) may form

in a noticeable degradation in
scanning quality. The following
conditions are recommended for
optimal scanning quality:
