I've recently purchased a Photosmart 6520 for a user here in the office that I've connected directly via USB. I've also purchased a Photosmart 7520 for home that I've connected to wi-fi. In both cases, they print fine, but neither can scan - constantly get a 'cannot establish communications' error.
I have followed their diagnostic steps, uninstalled/reinstalled, rebooted everything, again and again, etc., etc., with no success.
Any else run into these problems? Is there a solution besides returning these devices and avoiding HP consumer products?
