I even tried to re-install the Latest firmware and the earlier firmware (which I had saved about two years back) and the printer does not allow you to do that. I recently updated to the lasted build of Windows 10 version 1909 hoping that would correct the problem but it didn't. Actually, what does work is using the imbedded scan feature to PDF function writing it to a USB Flash drive inserted into the printer which is not very good quality. At some point, that fails then I have to go through the setup process again to scan. What does work for scanning every so often is the HP Smart App. It did initially work until the next time I rebooted my computer. So I de-installed the HP software again, and re-installed it but this time I selected the network option. However, after rebooting my computer about a day later and attempting to scan again, I hit the same situation. During setup, I selected the USB cable option and after the installation, I was able to scan. So i deinstalled the software and re-installed it going through the setup process. Using the instructions from the online HP Support, I used the HP Print and Scan doctor but that did not work. I attempted to scan via USB Cable using the standard HP Officejet software and got 'Cannot not find printer'. There were not Windows 10 updates that I installed. This situation changed the moment I downloaded and installed the latest firmware - 2006B released on Mar 27, 2020. I been been able to use my HP Officejet 8710 for scanning purposes for about 2 years without any problems.
