HP Officejet 7210:White hazy line on right side of scanning glass

Is it possible to disassemble the top of the scanning plate to clean the underside of the scanning glass on an HP Officejet 7210?

    It appears to be an accumulation of dust that I can't possibly get to through normal cleaning methods. Dust can get anywhere if there is not an airtight seal, which seems to be the case here. The line of dust is close to where the scanning bulb's resting position is.

Like many other people I have a vertical line down the copy, using the document feeder, not the plate glass. on my HP officejet J5780 3 in one. Your advice is to clean the small glass plate. I look...


I dont have a picture at the moment but if you lift the document feeder up to expose the large plate glass, the small plate glass is normally situated at the extreme left hand side of the large plate glass.

When I load papers into the document feeder on top of my HP Officejet 7210 All-in-One printer to scan these documents, the PDF file (scan results) have a multi-color series of lines from top-to-bottom on...


  1. Remove all originals from the document feeder tray.
    NOTE: It might be easier to work with the automatic document feeder if the document feeder tray is removed first.
  2. Lift the cover of the automatic document feeder. Figure 1: Lifting the ADF coverc00222493.gif
  3. Lift the lid on the HP all-in-one, and locate the notch near the top right edge of the lid backing. Figure 2: Locating the notch near the lid backingc00222494.gif 1 - Notch 2 - Lid backing
  4. Place one or two fingers in the notch, as you lower the lid of the HP all-in-one. Keep your fingers in the notch until the lid is almost closed. Figure 3: Inserting fingers into the notchc00222495.gif
  5. Push against the top of the face plate with your thumb as you pull the bottom away from the right side of the HP all-in-one with your fingers. Use a slight twisting motion to help release the face plate on the right side.
    CAUTION: Do not pull the face plate all the way off yet. There is a plastic catch on the far left inside of the face plate that helps secure the face plate in place. If the face plate is pulled straight off, the plastic catch on the inside of the face plate might be damaged. Figure 4: Releasing the face plate from the right side of the HP all-in-onec00222496.gif 1 - Releasing the right side with a slight twisting motion
  6. Slide the face plate to the left until the plastic catch on the left side is not touching any part of the HP all-in-one, then pull the face plate away from the device. Figure 5: Removing the face plate from the HP all-in-onec00222497.gif 1 - Sliding the face plate to the left 2 - Pulling the face plate away from the HP all-in-one
Cleaning the rollers or separator pad Follow the steps below to clean the rollers or separator pad.
  1. Once the face plate of the ADF is removed, use the blue-green handle to lift the pick assembly. Figure 6: Blue/green handle and the pick assemblyc00222498.gif 1 - Blue-green handle 2 - Pick assembly This allows access to the rollers and the separator pad. Figure 7: The rollers and the separator padc00222499.gif 1 - Rollers 2 - 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. If the residue does not come off using distilled water, try using isopropyl (rubbing) alcohol.
  5. Use the blue-green handle to lower the pick assembly.
Reattaching the face plate of the ADF Follow the steps below to reattach the face plate to the front of the automatic document feeder.
  1. Hook the face plate onto the left side of the HP all-in-one so that the plastic catch on the far left inside of the face plate catches on the notch on the front of the automatic document feeder. Figure 8: Hooking the face plate into the left side of the HP all-in-onec00222500.gif 1 - Notch 2 - Plastic catch
  2. Line up the right edge of the face plate with the right side of the HP all-in-one, and then press on the right side of the face plate until it snaps securely into place. Figure 9: Snapping the face plate into the right side of the HP all-in-onec00222501.gif
  3. Place your hands towards the center of the face plate, and press until the center of the face plate snaps into place. You should hear two clicks; one when the left side snaps into place, and one when the right side snaps into place. Figure 10: Finishing re-attaching the face platec00222502.gif
  4. Close the cover of the automatic document feeder.
  5. If you removed the document feeder tray, reattach it.

Vertical line appear on my HP OfficeJet J 6450


Look at the narrow glass and see if there's white out or anything on it, also the white reference guide above the glass needs to be clean as well. The skinny glass under the adf is where documents are scanned when not placed on the big glass.

Lines on my copies


As the page you wish to copy goes through the document feeder, it passes the scanner as well as a white plastic band that the scanner "compares" the dark writing or data on the page to. If this white plastic band is not very clean, the scanner reads the dirt as if it is part of the image you are scanning. Try cleaning the band as thoroughly as possible, as well as the small piece of glass to the left of the larger glass on the flat bed scanner. Make another copy to test your results.

Hope this helps!

Copying on my 7210 hp all in one


are you feeding in the copies from the Automatic Document Feeder? Open the top of the flat bed scanner and look to the left you will see a small piece of glass that is used for the ADF and then you will see a large piece of glass that is used for the flat bed scanner. Clean the small piece of glass used for the ADF and let it dry before trying to use the copier again. Test the copier and see if the gray line is still there. if you are using the flatbed portion of the scanner, clean the larger glass on the scanner and as before let it dry before trying to use the copier again and then test the copier.
