Why are the copy/scan functions not working?

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

"Oh it worked!!!

This is a nice printer. Very frustrating not being able to make a copy and a waste to just give up and toss it in the trash. I would have kept it as a regular printer minus the bells and whistles. Really hated seeing recommendations on HP Doctor and needing Windows. Regardless, came across this site and thread and tried it. It took a couple of tries but when I removed it from the glass desk and dropped it on the carpeted floor, I hit copy and sure enough, out came a printed copy. Thank you AND I will be RETURNING THE NEW HP PRINTER I JUST PURCHASED TO REPLACE THIS ONE. The new one is a higher model number, newer class and yet, cheaper quality.

Looking back and finding the secret menu to reset/partial reset blah blah blah, I just have to laugh at this resolution. THANK YOU AGAIN!"

I was amazed. I thought it was a joke but since I didn't have another answer and figured I'd have to buy another printer I had nothing to lose. Dropping the top wasn't enough. I had to actually drop the printer once on either side. Go figure.

To say I was sceptical of this would be an understatement, but, yes, it worked. Must be something in the mechanism which jams and the jolt frees it up. Scanning and copying working perfectly.

Miraculous! Thanks for tip. Hope HP is taking a note on this. Can’t believe none the resolutions recommended by the “HP Print and Scan Doctor” works, but this. I too thought it was a joke initially and thanks to all the positive feedbacks from all - convincing me to try. And, It works like a charm.

I, too, thought this was a hack-joke but figured I didn’t have anything to lose since I was about to buy a new printer (and not an HP again!). After the first two drops the printer started behaving differently, like the “Cancel” started working (but didn’t complete). Persistence paid off and after the fourth drop of both sides the Copy function began working. Will wonders never cease!! Thanks for this great tip!
