I'm in agreement with you, it doesn't seem right.
Let's look at the total workflow; maybe that will help.
1. Build scanner.
2. Capture images with scanner.
3. Copy images to computer.
4. Process images.
5. OCR images.
6. Bind resulting files into output format.
What, if anything, does this help clarify? I'd like to hear from Rob and/or Anonymous2, and/or Steve and Tulon, strider1551, Misty, etc... they work on software all the time.
