I found the drivers just yesterday--on the Agfa site where they are kind enough to leave a link--even though they no longer support the product.
I have a manual for the scanner and it doesn't mention the plug/transformer except to say "important to use the one that comes with the scanner. ( maybe I'll look at the online manuals ) The odd thing is--when we got this scanner it was missing the plug, and we had to get another from the comp. place. The plug we got never did look like the one
in the manual that's shown; sort of complicated-looking.
So I am still wanting to know: 16 or twelve volts? Cause I'm pretty sure the plug we got was one of the two.
