OfficeJet 9020 ADF duplex scanning skewed/slanted

[kennifu]

I just bought an OfficeJet 9020 for the duplex scanner. Whenever the ADF scans the back side of a page, it comes out skewed / slanted.  To be precise the scanned image of the back side of the page always comes out rotated 10 degrees or so. The front page is fine. Has anyone experienced the same?  This is a brand new OfficeJet 9020.

The scans come out fine if I just just ADF scanning one-sided.  Only the back page by duplex double-sided ADF scanning comes out slanted.

Hi @kennifu,

I'd like to help!

Try the below suggestions -

Clean the scan feeder

Clean the plastic and glass strips inside the document feeder with a soft, lint-free cloth sprayed with glass cleaner.

NOTE: 

Some printers ship with a document feeder cleaning cloth. If you have the cloth, load it into the document feeder and start a scan job to clean the scanner mechanism.

1. Turn the printer off, disconnect the power cord, and remove the battery if your printer has one.

2. Depending on your printer model, open any top cover, document feeder tray, and scan document feeder cover.

3. Remove any debris such as bits of paper or paper clips from inside the document feeder.

4. Spray a soft, lint-free cloth with glass cleaner, then wipe the scanner glass and the white strip on the underside of the document feeder until clean, dry, and streak-free.

      CAUTION: 

   To protect the interior printer parts, do not spray the cleaner directly on or into the printer.

5. Completely close any covers and trays that you opened.

6. Reconnect the power cord, reinstall the battery if necessary, then turn on the printer.

7. Load the original document or photo. Make sure the original document or photo is in good condition and free of tears, creases, folds, staples, or tape.

8. To avoid skewing, adjust the guides on the document feeder to remove any gaps next to the edges of the paper and the guide. The paper stack should slide easily into tray and not bind against the guides.

Clean the automatic document feeder (ADF) rollers

If your printer has an automatic document feeder (ADF), dust or paper residue on the rollers or separator pad inside the ADF can result in scan quality issues. Open the ADF, then clean the ADF rollers and separator pad.

NOTE: 

The location of the ADF rollers might be different depending on your printer, but the following steps still apply.

1. Gather the following materials:

   • A clean, lint-free cloth, or any cloth that does not come apart or leave fibers

   • Distilled, filtered, or bottled water (tap water might damage the printer)

2. Remove the original document from the ADF.

3. Turn off the printer.

4. Disconnect the power cord from the rear of the printer.

5. Open the ADF cover.

6. Find the paper pick rollers and the separator pad inside the ADF.

7. Lightly dampen a clean, lint-free cloth with filtered or distilled water, then squeeze any excess liquid from the cloth.

8. Use the damp cloth to wipe any residue off the paper pick rollers and the separator pad.

9. Leave the ADF cover open for two minutes to allow the paper pick rollers and separator pad to dry.

10. Close the ADF cover.

11. Reload the original document print side up in the document feeder tray. Gently slide the document into the printer as far as it can go.

12. Slide in the paper width guides until they are snug against the paper.

    Do not push the paper width guides in so far that they bend the paper.

13. Reconnect the power cord to the rear of the printer.

14. Turn on the printer, then try to scan.

Reset the product

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

Hope this helps! Keep me posted.
