I connected a new Dell 810 multi function printer connected to a customers new Dell XP system, and it would print, and copy, but scanning wouldn’t work (the software would give the error: device is not available

The software would give an error, and no amount of uninstalling and reinstalling software and drivers would make it work (even with the latest software from the dell website).

The best Dell support could muster was to use MS paint to scan via the twain interface.

After some prior work in trying to make an Epson 3490, I suspect there is a problem with the PC running on an Athlon 64 X2 processor (but cannot confirm it)… I’d really like to know if its the processor, the motherboard, or something else…
