OfficeJet R65 Scanner driver

Good day!

I have upgraded my OS form WinXP SP3 to Win7 Ultimate x64 SP1.
While I had XP, my OfficeJet R65 worked perfectly well, with all functions enabled, but now, Win7 only recognises it as a single R60 printer and I can't use the scanner.
Even if I manually add the R65 printer driver and remove the auto-found R60, It's the same.

I searched far and wide across the net for a solution, downloaded - and eventually - uninstalled lots of driver, disabled windows auto-update, configured it manually, etc. I even reinstalled Win7 a few times just to be sure.
Nothing worked.

Please help achieving full funcionality again! I like this printer very much and keep it in a very good condition, but I also - very much - wish to use the scan function on it.

Thanks!
