@hjlkhadd, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
If your OfficeJet Pro 8720 is scanning only solid black images, this typically points to a hardware issue with the scanner, such as a dirty scanner glass, a malfunctioning scanner light, or a problem with the Automatic Document Feeder (ADF). Here are some steps to help you troubleshoot and hopefully resolve the issue:

Check if the issue is with the flatbed or ADF

• Try scanning from both the flatbed scanner and the ADF.
• If one works and the other doesn’t, the issue is likely isolated to that specific scanning method.

Clean the scanner glass and white backing

• Power off the printer and unplug it.
• Use a soft, lint-free cloth lightly moistened with glass cleaner (never spray directly on the glass).
• Clean:
  • The scanner glass
  • The white backing under the scanner lid
  • The ADF glass strip (if present)

Reset the printer

• Unplug the printer while it is powered on.
• Wait for 60 seconds.
• Plug it back in and power it on.

Update printer firmware and drivers

• Ensure your printer firmware is up to date.
• Visit the HP OfficeJet Pro 8720 support page
• and download the latest firmware and drivers for your operating system.

Try scanning using HP Smart or another app

• If you're using HP Smart, try scanning with Windows Fax and Scan or another scanning app to rule out software issues.

I hope this helps. 

Take care and have a good day.

I suspect that the recos from Max3AJ would help most problems as it seems that almost all electronics need to be reset or rebooted or reinstalled. That said, I tried all of Maxs  recos but they did not work but would probably work if that would have been my problem.  I did find a solution and which was incredibly simple and perhaps it could be added into the list of recommendation from Max.  Even after trying many un-plug & re-plug wait for 30 minutes  etc. solutions the one procedure that worked for me was unplug for 30 secs followed by hold the power button on while unplugged for 30 secs to de-charge the system.   It took me more than a month to find a fix for this. I will add that I tried contacting the  HP  Help desk 3 times and I never got any live support. I will also add that the Smart Ink cartridges work perfectly even though I had 2 sets of original HP cartridges that have chips on them that go outdated in the obvious attempt to sell you mor ink.  I know that HP is terribly sorry for my inconvenience and I know that my business is important to them but they need to do more that read the words of off a script sheet they need to offer solutions not withstanding buy more ink from me or find the solution yourself on line because we do not offer any live support.   Shaq.....call me...
