Hi Lou,
It is possible that the HP-7400A isn't on the scanner list. There is a
complete list of usable scanners on the Freedom Scientific website. Don't
expect a newer model to work, it might not. I got a newer one and it would
only scan one page and I would have to turn off Open Book and restart it
again. That isn't any way of scanning.
