L7780 is a very new printer and could still be under warranty. I would check with http://www.hp.com before I tried to repair anything.

The document feeded is not pulling the paper. What should I do? Do you have this part for sale? How much?


Is this happening on TOP Feeder or Actual Paper Tray..

Turn off the printer
Remove the TOP ADF Cover and Clean the Rollers with lint free cloth
Remove the Rear Access door and clean the Rollers

Close the Doors and turn on the printer.

The auto document feeder does not pick up the paper


The pickup roller is probably dirty. Take a clean sheet of paper and put a small amount of rubbing alcohol at the end. Take that same end and place it in the automatic feeder and attempt to feed through for a few times. This should clean the pickup roller and allow paper to be picked up. Wait a few minutes for the alcohol to dry and attemt to feed a clean sheet of paper. You might need to repeat the process a few times

The auto-document feeder on our HP L7780 OfficeJet Pro printer doesn't pick up the papers anymore. The 'gears' are spinning, but the papers aren't advancing. I've cleaned the rollers, but that still didn't...


I put an elastic band around the black roller as it doesnt seem big enough and it works nearly every time now. Have done this with another L7780 Pro as well which fixed it completely on that one.

Auto document feeder


Did you make sure the tape is removed inside the Document feeder,or maybe you need to check to see if anything is stuck in the rollers. Open the door (if you have not already done so) to the document feeder and you will see pictures on the inside showing how you can remove and/or change the roller (make sure everything is put back as the picture. Good luck, I hope that is all that is wrong with it.

Document feeder


Its most likely to be the pickup roller and separation pad which will need replacing. as a short term fix try cleaning them with some isopropyl alcohol
