HP SCAN APP FOR HP SMART TANK 790

[EEB70]

Hello everyone, I just installed the latest "HP Scan" app (HP Universal Scan - Full Feature Software and Driver / 63.6.6364 / 439.6 MB / Nov 3, 2025) for my Hp Smart Tank 790 and it is not working.   I installed it in my laptop HP Envy x360 running MS Windows 11 Home (64-bit).  Any ideas to fix this problem?  Thanks.

Hi @EEB70,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your HP Scan app for the HP Smart Tank 790 is not working on your HP Envy x360 running Windows 11. Let’s go through a few HP-focused steps to troubleshoot this.

Confirm printer connection
Make sure your HP Smart Tank 790 is powered on and connected via USB or the same Wi-Fi network as your laptop.
Check that the printer is recognized in Devices & Printers in Windows.

Run HP Print and Scan Doctor
Download and run the HP Print and Scan Doctor from HP’s official site.
It will detect connectivity issues, driver problems, or conflicts that prevent scanning.

Verify HP Scan app installation
Open Control Panel > Programs and Features and ensure the full-feature HP software is installed.
Sometimes uninstalling and reinstalling the full-feature software, rather than just the Universal Scan app, resolves missing components.

Check Windows app permissions
Go to Settings > Privacy & Security > App permissions > Camera / Files and make sure HP Scan has access.
Without proper permissions, the app may fail to detect or communicate with the scanner.

Restart print/spooler and services
Press Win + R, type services.msc, and restart the Print Spooler service.
This refreshes the communication between Windows and HP scanning software.

Update Windows and printer firmware
Ensure Windows 11 is fully updated via Settings > Windows Update.
Check HP Smart Tank 790 firmware via HP Smart app > Printer Settings > Update; outdated firmware can cause scanning failures.

Test scanning from HP Smart app
Open the HP Smart app and try scanning directly from there.
If scanning works in HP Smart but not in HP Scan, the issue is with the Scan app configuration.

I hope this helps.

Dear Kuroi,

Thanks four your answer.

I followed all the steps you provided me and the problem still persists.

I forgot to tell you that the HP Smart app works fine.

The one that doesn't work is the HP Scan app, which is well configured.  I double click it and  a window appears like it is going to open (please see attached screenshot) and then, suddenly disappears.

Any other ideas?

Best regards.
