If you have Microsoft Office 2003 or Microsoft Office 2007 installed you have something called Microsoft Office Document Imaging, or MODI, which can perform OCR on Tiff and BMP files and is scriptable. If you capture the screen, or a window, to a bitmap file, you can use MODI to perform OCR on the screen, or a window, to get its text.

If running Office 2007 MODI is not installed by default.
Run your office setup and select from the installation options to install the MODI components.

-----------------------

OmniPage from Nuance (formerly by ScanSoft) has been successful for some of my application needs, but over $100.  Try MODI first if already have files and need OCR.  OmniPage will work with physical scanner hardware to scan and do OCR or just save in different formats.

---------------------------

Also mentioned OmniFormat in an earlier posting to covert images into PDF files.  Direct output from scanner directly to a "PDF Folder" and process is done..  Since you need no processing, this may be a good software solution that will work with any scanner.

Any volume of scanning does require a stack feeder of some sort. 
Manually insertng pages, aligning, handling covers, etc. is too much wasted effort.
