Online adjustments can affect the width and location of the scan
beam. Use these adjustments to make minor changes to an
application, not to compensate for improper installation.
See the AdaptaScan User Manual for descriptions of Usable Beam
Width, Scan Angles, Skew/Pitch/Tilt and Apparent Element Width.

•
Upper and Lower Angles (raster scanning only) – adjusts the
