HP all-in-one printer

I recently purchased an HP Smart Tank 7602 all-in-one
printer, which includes a scanner. My installation of the
sane and xsane software was not able to recognize the
scanner and I did not see this printer or the 7600 series
of printers listed among the supported devices. I first
wanted to verify that the 7602 printer is indeed not supported,
and I also wanted to ask if there might be any development
effort to support the scanner in these HP all-in-one printers.
Thank you,

Richard
