Prescan Setup; Overview Area - Microtek ScanMaker 6100 Pro User Manual

determined by your scanner model's bed size. You can, however,
customize the overview area so that the scanner consistently
overviews only the specific dimensions you have in mind. For
example, if your maximum scan area is 8.5" x 14", you can
customize the overview area so that it consistently overviews, say,
4" x 8" of the bed size.
As a rule of thumb, it is best to use the default maximum settings.
You should change the overview area only if your subsequent
overview is too large to be shown in entirety, or too small for
reliable previewing. A smaller overview area will increase the
overview resolution for clearer image viewing. You may also wish to
change the size of your overview to improve performance.
Generally, a shorter overview time results from the scanner motor
travelling at a lesser distance.
Fast Overview/Fast
The Fast Overview/Fast option supports faster scanning. If Fast
Overview is unchecked, the Overview scanning speed is slow, but a
better overview image quality is obtained.
