I had this problem too. Printer works. Scanner and copier won't work. Uninstalled drivers, and reinstalled drivers, numerous times. Didn't help! Did hard reboot. Didn't help. Got mad! lifted right side of printer 6 inches and dropped it on the desk. Lifted right side of printer 6 inches and dropped it on the desk. That fixed it. Now it is working as it should. the problem was not a software issue, but a hardware issue. I suspect, a small short in a contact somewhere inside, Which may very well reoccur. NOT MUCH HELP FROM HP
