Well I have tried the Windows XP and 7 drivers and applications and
although they can find the printer, they cannot find any scanning device.
So just the same as the Linux situation which doesn't surprise me that much.

I just wondered if it was doing scanning by some surreptitious means
through the printer interface or by uploading some firmware.
It will actually do an internal copy so the scanner actually does work.

There isn't much of an interface to explore resetting. I cannot find any
firmware for the machine although I can get the firmware downloading
utility. I have a suspicion that the issue is with the device itself.

Bit of a mystery really.

Cheers,
