PDF Scanner Option
My scanner is not TWAIN compatible and only creates PDF's (using its own proprietary software) so I found a program that is a Virtual Twain Scanner, that imports a PDF in as a Twain image.
Goto http://www.scanworkssoftware.com/ to get it.
Install the software.
When you goto RGP's Bulk Scan page, Select the ScanWorks Scanner as your scanner.
Enter the number of pages as the number of pdf files in the folder.
Click "Scan Now"
ScanWorks will popup.
Select your source folder.
After it processes the files RGP will allow you to review the images like normal.
Now the software isn't free but it is cheaper than purchasing a new scanner if you already invested in one that only does PDF's.
