Into Unimessage Pro, from TWAIN Scanners

Unimessage Pro also provides a function that allows you to build a multi-
page document from several separate TWAIN scans.
This is useful if you want to scan different pages with different settings, or
if you want to scan both sides of a document. It is used as described
below:
Select Multiple Scans from the File menu.
The Unimessage Pro Scan Multiple Pages dialog appears:
Click the Help button on this dialog for more details of how these

If you acquire images at asymmetric resolutions such as 200
x 100 dpi and 200 x 400 dpi, you will be able to view them in
Unimessage Pro, but may experience problems with
displaying them in other Windows applications. If your image
appears distorted when scanning at these (or other
asymmetric) resolutions, scan again using square
resolutions instead, e.g. 200 x 200 dpi, 300 x 300 dpi, etc.
Asymmetric resolutions will also usually yield poor OCR
results.
