Hello, I am new in this mailing list and I actually just subscribed to help getting the scanner part of HP Photosmart 7510 (a multifunction device) working. I own one, and the printer part is working well using the HPLIP. As I see there is no SANE support for this device so far. I will post the shell outputs mentioned on the "Contributing" page soon. Also it would be possible to open the device, but I want to use it further so I will not do anything that destroys it.
Kind regards, bflehner
