Hi @Victor40

Welcome to the HP Support Community. I'd be happy to assist you.

Let's try and uninstall the printer software from the root level on your PC and install the full feature printer software.

--->In Windows, search for and open Programs and Features.

--->Select your HP printer.

--->Select Uninstall.

--->In Windows, search for and open Devices and Printers.

--->In the Devices and Printers window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”

--->Open up the run command with the "Windows Key + R" key combo.

--->Type printui.exe /s and click OK.

--->Click on the Drivers tab.

--->Look for HP Printer driver. If you see it click on it and click remove at the bottom.

--->Select OK.

--->Select Apply and OK on the Print Server Properties windows.

--->Close Devices and Printers.

And then reinstall the printer full-featured drivers from software and drivers page 

Restart WIA-->

• Open the Run window again, type “services.msc” and press ok to get services window.
• Scroll down to Windows image acquisition stop and restart the service  

Hope this helps! Keep me posted.

It was on a new computer with a clean OS.
There was no printer installed at all.
The printer and fax driver installs well, but the problem is only with the scanner driver.

Have you installed any security software on your computer?

Could you turn the firewall off and then try installing the drivers

[Victor40]

No security programs, no firewall, UAC turned off, driver digital signature verification in group policies  is also disabled .

but the scanner driver is still not installed for the same reason.

3. Launch the app, select the printer, and then let the utility automatically install the software and add the print queue.

   NOTE:

4. Place the item that you want to scan on the scanner glass, or load it into the automatic document feeder (ADF).

5. In the Applications folder, or from the Dock, select HP Easy Scan.
