Welcome to HP forums, I see that you are getting scan quality issues.

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.

      NOTE:

   HP recommends connecting the printer power cord directly to a wall outlet.

5. Reconnect the power cord to the printer.

6. If you have an HP DeskJet 3700 series printer, calibrate the scanner after resetting the printer.

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

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.

Change the scan settings

1. Load the item on the scanner glass, in the document feeder slot, or in the automatic document feeder (ADF), depending on your printer type and features.

      NOTE:

   Do not load photos in the ADF to prevent damage to the photos and the printer.

2. Search Windows for your printer model, then click the printer name in the list of results.

   HP Printer Assistant opens.

3. Click Scan, then click Scan a Document or Photo.

   HP Scan opens.

4. Click one of the shortcuts that matches the file type and resulting action you want.

5. Change any of the shortcut default settings in the right side of the window, if necessary.

      NOTE:

   Available settings change depending on if you are scanning a document or photo. For example, the PDF File type is only available for document scans.

6. Select Show scan preview or Show Viewer After Scan to preview and make additional edits to the scan before saving it.

7. Click Advanced Settings or More to change settings such as quality, color, and default scan destination folder.

8. Click Scan.

   The printer scans the item, then a preview of the scan displays in HP Scan.

9. If necessary, double-click the thumbnail image of the scanned item, then change any additional settings.

10. Click Save.

    The Save as windows opens.

11. Select the folder you want to save the scan to, change the File name if necessary, confirm the file type in the Save as type menu, then click Save.

Hi, managed to get a support tech to do a web session and he tracked it down to a bad scanner bar.  It's taken over 1 1/2 years to figure out this problem and the printer is out of warranty now so  HP won't do anything about it.  Disappointing considering I'd spent over 30 hours on various tech sessions with HP support trying to resolve this.
