Question about HP Officejet Pro L7780 All-In-One InkJet Printer

1 Answer

Feeder won't pull paper

The feeder on top of the unit has worked great until recently. Now it won't even pull in one sheet of paper to copy. Cleaned rollers and flat scan area and messed with the rollers to see if they just weren't making good contact with the small piece of cork underneath. Wondering if we have just worn out the cork til it is so smooth and indented that it won't grip the paper to pull through? (HP Officejet Pro L7780 All-In-One-Printer)

    The paper feed works at times , at other times it just spins and says reload.

    Don't know what to do.

    I sometimes have the same problem...sometimes the feeder (when sending a fax) will take the paper and other times it just makes the noise, but the foot isn't dropping to make contact with the paper...the one solution that I have found that sometimes works, is using the Guides on either side of the paper, and pushing them closer together, making it more of a snug fit for the paper and so that it straightens the top portion of the paper that is not inside of the feeder... Not a solution but sometimes it works!

The arm in the printer is a cog setting you may have inadvertently knocked it out of alignment, it has free movement on a pivot and spring but when the printer uses it, it pushes on the mechanism to grip the paper and the roller at the bottom freeds it though, sometimes using to thick paper can do the samething. you would need to open up the device and locate the mechanisms, and make sure there is noting in the way of the controller's, i've seen a tiny piece of silver rapper make the same problem.

Change the D roller AND the cork block (paper separator pad assy.) If either are worn it can pick multiple sheets.

SOURCE: The auto-document feeder on our HP L7780 OfficeJet

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.

SOURCE: Top paper feeder roller rotates but does not draw in the paper

I had the same problem... If you take the upper feed roller assembly off you there should be a grey rubber pad about 1.5 inches wide. This pad is held in place by a small metal clip. You will probably find that the pad has pulled out of the clip. I bent the clip to hold the pad a little tighter and has worked fine since. There was no problem with the rollers.

Paper jam I've cleaned sprayed,etc must be something I can't see w/o going deeper. How do I remove cover to get to paper rollers in MX340


Removing the covers is not the answer. Most jams on rear feed printers/faxes are due to some object falling in the sheet feeder. When you pull the paper back out (Very slowly) of the sheet feeder after it has jammed , you will see a nick in the paper. This is because the paper is hitting something and cant get past it. put the paper back in the sheet feeder and the nick will indicate where the object is. Find a large paper clip and unwind it and bend the top of it to 90 degrees. use this to hook the object out and then tip the printer upside down and watch it fall out. Good luck

Paper feeder pulls multiple sheets of paper


PULL ALL PAPER OUT OF MACHINE EVEN THE SUPPLY, UNPLUG OR TURN OFF THE POWER TO THE UNIT, PUT A STACK OF PAPER IN THE SUPPLY TRAY & GENTLY PUSH FORWARD NOT FORCING IT UNTIL IT STOPS. TURN POWER BACK ON & TRY AGAIN. YOU MAY HAVE TO REPEAT THIS 2-4 TIMES BUT IT WORKED FOR MY HP DESKJET F4180 ALL IN ONE.

Multiple pages feed when printing on hp 7410


  • If the automatic document feeder (ADF) does not pick up any pages at all, the rollers inside the automatic document feeder need to be cleaned.
  • If the automatic document feeder picks up multiple pages instead of single sheets, the separator pad inside the automatic document feeder needs to be cleaned.
SolutionLoad one or two sheets of unused plain white full-size paper into the document feeder tray, and then press Start Copy Black to pull the pages through the automatic document feeder. The plain paper releases and absorbs residue from the rollers and separator pad.note.pngNOTE:If the automatic document feeder does not pick up the plain paper, try cleaning the front roller. Wipe the roller with a soft lint-free cloth dampened with distilled water. If the problem persists, or the automatic document feeder does not pick up the plain paper, clean the rollers and separator pad manually. Follow the procedures below to remove the face plate from the front of the automatic document feeder, access the pick assembly inside the automatic document feeder, clean the rollers or separator pad, and then reattach the face plate.

try to Load one or two sheets of unused plain white full-size paper into the document feeder tray, and then press Start Copy Black to pull the pages through the automatic document feeder. The plain paper releases and absorbs residue from the rollers and separator pad.

Paper either just rolls through without printing or won't catch and sits there


This has occured to a 2.hand printer I just bought. First head was clogged very much. I disassembled the head, used a paper towel soaked in luke warm water to clear off the over-gooed printing head surface. It is quite easy to get the head out and back in. Unfortunately my cyan ran out during clean-cycle, so I can't say if it also cured the passing paper problem.

Dell 1600n Will only print with sheet feeder open


Rollers may be worn out and not properly grabbing paper or a gear may be broken. You should be able to inspect by lifting cover to feeder and watching as paper is pulled through.

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

Erratic operation thru top copy/fax function


I don't really want to get into this, but you sound desparate. i don't work on your model very often, so bear with me. When a sheet jams, don't just pull it out. Open the document feeder as far as you can and note where it stopped (the side tha DID NOT feed). Look for a possible obstruction or even spot of something that looks dirty or sticky. If so, remove or clean it. Look at the leading edge of the jammed sheet, see if there are any indentations that could possibly line up with a sensor flag, roller edge, etc. Last suggestion. Press down of the side of the document feeder that DID NOT feed through. If this helps, then there is a problem with the latch that holds the document feeder closed. Without seeing the unit it is difficult to diagnose correctly. Let me know one way or the other. Any observations will be helpful. Ed One more thing! Make sure the leading edges of the pages you are sending are perfectly straight and smooth. Make sure that they HAVE NOT been stapled at one time (the indentation can cause a problem)
