HP M3035 ADF has two black plastic pieces that interact with the roller gear assembly. One black piece has a cutout that fits around the blue button that you press to release the roller gear assembly and...


Unfortunately for this model the ADF section isn't broken down into it's individual components,
the part numbers available for the ADF are as follows: (direct from the Service Manual)

Control Panel
CB414-60101

Cover, ADF
CB414-67902

ADF feed roller kit
CB414-67904

Input tray, ADF
CB414-67903

ADF assembly
CB414-67916

Scanner assembly (ADF assembly is not included)
CB414-67905

However your best bet would be to call around to all of your local printer repair shops in your area and asking them if they have any of these M3035's sitting around for spare parts.
Otherwise I could try to find a good picture of the ADF Feed roller kit and see if it contains the parts you're looking for.


Hope this helps! If so please don't forget to leave a positive review for me. :)

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.

    The adf doesn't work. I have tried taking the rollers out and reinstalling, but the rollers still don't drop. I


    there is a lever-like device that is deflected when paper is inserted into the feeder. It interacts with an optical device to detect the paper.
    The feeder mechanism cover should hinge to the left. The latches tend to be stiff so don't be afraid to apply some pressure. Look for the lever on either the cover or the bottom surface of the feeder. It should hinge easily with light pressure.
    Sometimes the lever gets unhinged. There is a plastic sensor that moves back when the paper is loaded in the ADF.

    the lever (plastic sensor) has a "flag" on it that interrupts an invisible light (infrared) beam in the optical sensor (optical device). The sensor is typically a small black device with slot in it. The flag moves through the slot without any physical contact. The sensor will not be visible without removing a cover of some sort.

    there could be mechanical damage or misalignment. The failure could be one of the following:
    1. The optical sensor is defective.
    2. Since various sub assemblies in the printer are interconnected using cables, there may be a cable plug thats not mated securely with it's corresponding socket.
    3. A component on the main electronics board has failed.

    there are many other users facing the same exact problem with ADF not loading document and its not getting detected on front panel.

    SUDDENLY THE ADF DOSEN'T WORK I GET AN ERROR MESSAGE THAT THERE IS A DOCUMENT IN ADF REMOVE AND PRESS OK


    Problem:
    I place a stack of originals in the ADF and press Copy or Scan. There is a sound of a motor running, a pause, and then the motor running again. The paper is supposed to feed during this second phase but does not always feed. For me, it would fail to feed, ask me to clear the ADF, and press "OK" a random number of times and then suddenly it would work once or twice and then fail again.

    Diagnosis:
    I am a retired engineer and my feeling was that if could work properly even once, then it should work every time. The problem must be something intermittant relating to temperature, humidity, age, etc. It must be easily fixed.

    Solution:
    The rear of the ADF has a silver-grey plastic piece which covers the feed motor and gears. You gain access by removing the one Phillips screw, opening the lid, and carefully prying the retaining lip at the right end of the silver-grey piece until it lifts up. The piece is then removed by sliding the retaining "leg" free at the right end of the piece.

    Inside, you will see some white plastic gears. One gear is mounted on a floating idler arm. This gear controls feed and reject (I think). The feeder fails when this idler does not flip freely from one positon to the other. Carefully place a SMALL amount of very light (low viscosity) oil on the ider arm and verify that if easily moves back and forth.

    Test the unit before replacing the silver gray cover piece.

    That fixed it for me.
