Scanning, Faxing & Copying

I have used this HP LaserJet 1536dnf MFP for many years. Its scanning software worked great. It stopped working recently when I installed a mesh system to fix poor Wi-Fi coverage. I had to uninstall the printer and reinstall the HP LaserJet “Full Feature Software and Driver,” which I had done in the past without issue. This time, though, when I reinstall the software, the printer works but the scanner does not work. I have downloaded and have run the HP Print and Scan Doctor 5.7.4 from that same website. It tells me a very long error message. The essence of that error message is that it cannot find the HP Scan application software in my computer. It does cause the scanner to scan, and the 1536’s display says “Scanning to PC” like it used to when the scanning worked.

It should be noted that I am not using Wi-Fi. The LaserJet 1536dnf’s Ethernet port is wired to the modem/router with an Ethernet cable. The two Windows 10 PCs also have Ethernet cables from them to the modem/router.

I already followed all the steps in a post from 05-26-2022 by @Woody1294. That did not fix the problem.

Coming to this HP Community, I clicked on “Scanning, Faxing & Copying.” There I read this message:

“NOTE: From May 1, 2024, the HP Scan and Capture app will no longer be available (retired) in the Microsoft Store and HP will not release any further app updates.”

I do not know if that is the problem, although it is not yet May 1, 2024.

Can anyone offer a way for me to fix this?
