Blue veritical line appears on a scanned document using the auto feed. It does not appear manually

Blue vertical line appears on a scanned PDF document when using power feed. If you manually scan each page off the glass it does not appear. I have uninstalled and reinstalled twice and I have updated all software and drivers?

Welcome to the HP Forums. I would be happy to help you with your HP OfficeJet Pro 8725 Printer. I understand that you are getting vertical lines when you scan from ADF and you have already done some preliminary

troubleshooting.

Don't worry though as I have a few steps to determine the issue and find a solution as well,

Clean the automatic document feeder (ADF) rollers.

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 printer.

1. Remove any items from the scanner glass and automatic document feeder (ADF), then close the scanner lid.

2. With the printer turned on, disconnect the power cord from the printer and from the wall outlet or power strip.

3. Wait at least 60 seconds.

4. Plug the power cord back into a wall outlet.

5. Reconnect the power cord to the printer.

6. Load the original document or photo, then try to scan.

Click here and refer the document to perform the above steps.

Let me know how it goes.

Cheers.

Hello: I followed the directions below, and that does not solve my problem. Any other suggestions? Please advise. Thank you.

DIdn't work here either.  Only blue vertical lines on scanning.  Doesn't happen when I copy items in automatic feed.

Why doesn't this thing work?
