Officejet 6500 A Plus
Mac OS 10.7.2 (Lion)
Just got it and the first time I try to scan I have this problem. In fact when I attempted to use the HP Scan 3 application that came with it I also got an error. Go figure.
Error from HP Utility: Communication Error - Unable to communicate with device. Check cables and connections. If the problem persists, try restarting your computer and HP device.
I am trying to connect via wifi so there are no cables and I rebooted both devices with no luck.
Error when attempting to launch HP Scan 3: HP Scan 3 cannot be opened because of a problem. Check with the developer to make sure HP Scan 3 works with this version of Mac OS X. Blah, blah, blah.
Jeez, I jsut bought it. I downloaded all the drivers and software from the HP web site since the DVD was a PC DVD only.

Let's repair disk permissions on your Mac:
Open Finder and go to Applications > Utilities > Disk Utility.
Select your Macintosh HD on the left, then click "Repair Disk Permissions" button along the bottom.
Let it finish.
Restart your Mac.

I had EXACTLY the same problem, with the same printer and same version of Lion. I tried the Repair Disk Permissions as the tech suggested and this did nothing to help. They just sent me a new printer, I plugged it in and DARN if I don't immediately get an error message that I can not find anywhere on the HP site!!! I had MANY problems with this printer - always having to remove the printer, then add again in Systems Prefs. Not sure it really is going to work well and consistently with Lion and my Mac.
