Nuance omnipage direct 2 for windows User Manual

  When using an automatic document feeder (ADF), Direct 

will prompt you to insert each page rather than scan until empty. To scan 
with the flatbed, please disconnect the ADF from the back of the scanner.

  If images scanned in grayscale mode with an ADF appear 

distorted, please contact Microtek and upgrade your scanner ROMs to 
version 1.2.

You may be able to use a TWAIN scanner not tested by Caere if you edit 
the scanmgr.ini file that is located in your Direct directory. If you are an 
experienced user, open scanmgr.ini and follow the instructions at the 
beginning of the file. 

In your TWAIN data source dialog box, you must use these settings: 
Resolution: 300dpi; Scaling: 100%; Scan Frame: 8.5" x 11" or 8.5" x 14"; Scan 
Mode: Grayscale or Line Art.

If you select grayscale mode in the TWAIN data source dialog box, you 
can select Auto Intensity in the Direct Options dialog box. If you select line 
art mode in the TWAIN data source dialog box, but you have a grayscale 
scanner, deselect Auto Intensity in the Direct Options dialog box. The Size: 
setting in the Direct Options dialog box must be as large or larger than the 
setting in the TWAIN data source dialog box.

A copy of a standard scanmgr.ini file appears below.

;If your TWAIN scanner is not 100% compliant with the 
;TWAIN specification, you will need to add a section 
;to this file similar to the existing entries. Add an 
;entry such as the following. (Remember to remove the 
;semicolons and comments.)

;[Name of your TWAIN data source]
;SHOW_UI=0   
;INVERT=1
;AUTO_BRI=1

;SHOW_UI=0
;The above indicates whether or not the TWAIN Data 
;Source user interface will be displayed or not.
;0 means no, 1 means yes.

;INVERT=1 indicates whether the image will be
;inverted or not. If your scans appear as black
;pages with white text, and INVERT=1, make INVERT=0.
;If INVERT=0, make INVERT=1.
