Paper Jam In the ADF Automatic Document Feeder HP Officejet 5740 8040 Envy 7640 

Thank you! Not sure what the problem was, but when I took it apart and put it back together, it worked!! Thanks again!

That worked like a charm. I did not have a jam in the ADF but after completing the step outlined in the video the issue was resolved. THANKS!!

Thank you -- I didn't know was ADF was - this solved my problem.

Thanks bro! It's funny you said something about moving the printer because I actually had to move the table that was sitting on and the printer because I had my carpets cleaned. Obviously the sensor must have got stuck I did everything that you said clean the rollers check the sensor and put everything back and now it works. When I was searching for this problem your video popped up first. So appreciative of you putting out that video. I would have end up calling HP and they probably would have charged me for trying to diagnose the printer. that's a lot of help and to anybody out there that's watching this video it's solved my problem just like he said again a lot of thanks!

what about opening the back. looks like there is paper in the back. can the back of the printer be opened?

Thank you sooooo much one happy office professional

my paper jam is down below inside the printer

My sensor does not ding like yours. Any suggestions

my PANTUM M6600NW printer is asking me put papers on ADF in order to printer, What could be the problem?

Replacing the cover after removing it

followed this video,still doesnt work.error message "remove and install the indicated ink catridge making sure it is correctly installed and then touch ok" comes up nonstop no matter what.tried everything.
