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.

HP Officejet Pro LP 7880 feeder does not work, how to fix it?


Step one: Check the paper in the ADF The condition of the paper or the amount of paper loaded in the ADF might prevent the ADF from picking it up and feeding it through the product.
  1. Make sure that no more than 50 sheets of paper are in the ADF input tray.
  2. Make sure the original is not photo paper or carbon paper. These types of originals must be loaded on the scanner glass.
  3. Make sure the original document that is loaded in the ADF meets the following criteria:
    • Free from curls, folds, creases, and tears
    • Does not have staples or clips attached
Step two: Make sure the ADF pick assembly is in good working condition
  1. Remove the document feeder and open the ADF cover.
  2. While lifting the blue-green lever, carefully rotate the pick assembly toward the open ADF cover until it stops.
  3. Examine the pick assembly.
    • Make sure the bottom roller is held firmly in place by the two-catch, which is located to the left and the right of the roller.
    • Make sure the stack stopper, which is located between the top and bottom rollers, fits within the double slots just above the bottom roller. The stack stopper should move freely within the double slots to flow up and down when the whole pick assembly is lifted and lowered into position.
  4. Return the pick assembly to its original position.
  5. When the product is turned on, the top roller will reset to its original position above the separator pad. There will be a gap between the separator pad and the top roller.
  6. If there is no gap between the ADF top roller and the separator pad, press the Power button to turn off the product.
  7. Wait three to five seconds and then press the Power button to turn the product on. The ADF rollers should reset to the correct positions.
  8. Close the ADF cover and replace the document feeder.
Step three: Clean the rollers and separator pad
  1. Remove the document feeder and open the ADF cover.
  2. While lifting the blue-green lever, carefully rotate the pick assembly toward the open ADF cover until it stops.
  3. Lightly dampen a clean, lint-free cloth with distilled water, and then squeeze any excess liquid from it.
  4. Use the damp cloth to wipe any residue off the rollers and the separator pad. If the residue does not come off using distilled water, use isopropyl (rubbing) alcohol on the cloth instead.
  5. Return the pick assembly to its original position.
  6. Close the ADF cover and replace the document feeder.
Step four: Detaching and re-attaching the ADF pick roller assembly If the ADF pick assembly is detached or not connected properly, follow the steps below to resolve the issue. If the ADF pick assembly works well, do not perform these steps.
  1. Press the Power button to turn off the All-in-One.
  2. Remove the document feeder and open the ADF cover.
  3. Press the blue-green ADF-release button to release the ADF rollers from the pick assembly as shown in the figure below (the red arrow is pointing to the ADF release button).
  4. Re-attach the ADF pick rollers by placing the rollers into the roller slot of the ADF pick assembly as shown in the figure below. The red arrows show the gears on the ADF pick assembly aligned on one side. The yellow arrows point to the two-catch notch.
  5. Once the rollers are placed on the two-catch notch, push them in, so that the two-catch clicks into place. The photo below shows a correctly installed ADF pick assembly.
  6. Close the ADF assembly and cover.
  7. Turn the product on and make a copy with the ADF to check that the pick assembly works.

I have a message coming up that I don't know what it means.


ADF = Auto Document Feeder (Usually on top)

RADF = Rear Auto Document Feeder, (On the back)

Something is stuck in one of these, a piece of paper, foam, paperclip, twist tie . . . it could be anything. Follow the squealing sound and check the paper feeder rollers.

Find what is in the way and remove it.

Cheers.

The copy paper feed misaligns and jams, what's the fix? Jack


to fix misalign and paper jam problem, follow this steps.

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.
NOTE: 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 steps below to clean the rollers or separator pad.

1.Lift the cover of the automatic document feeder. This allows access to the rollers and the separator pad.
2.Lightly dampen a clean, lint-free cloth with distilled water, then squeeze any excess liquid from the cloth.
3.Use the damp cloth to wipe any residue off of the rollers or the separator pad.
4.Close the cover of the automatic document feeder.
This should solve the problem. Cheers!

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.

Won't copy document through feeder.


When you say it won't copy, do you mean that the paper won't move in the feeder or that no copies come out? Do you get any error messages? Try using alcohol on a swab or lint free cloth and clean the feed rollers in the feeder. They sometimes get paper dust on them and they can't pick up the paper. Also make sure that any paper sensors that detect when paper is in the feeder are intact. Occasionally they get stuck or broken. Hope this works.

Jam in the document feeder


I think I found my answer. You don't have to un do any screws. Lift up the cover to the automatic feeder. You will see a spring on the side of the mechanism towards the front; remove the spring; that will allow you to lift up the little arm the spring was attached to and remove the roller or bar and the light blue/green plate just under it. Then you will be able to see the jammed paper, which which I was able to carefully pull out with a pair of tweezers. Some was under rubber rollers, but when I pulled the paper sideways it slipped out. Now it works!
