We have a Hewlett Packard Scanjet, a C7670A - and a Windows XP computer. The problem: HP.com doesn't say the first word about a C7670A. I had to dig through the Internet's left pocket and come out with a fuzzy slip of paper that had been washed and dried in somebody 's pants . . .
well, it wasn't that bad, but how hard would it have been for HP to have SOmething on their website that gets you where you're going, starting from the part number on the device instead of the (unmarked) model number?
The C7670A is a 6300c in disguise. You need a 95 Megabyte file from the Hewlett Packard website. I haven't tried the document feeder yet, but at least it's got us scanning and printing without any additional fuss thanks God!
