Welcome to the HP User Community.

If you have not done so,

Check that your HP Smart application is running on the latest version.

If it is not running the latest version of the app, try to update it.

If that does not work, Uninstall the app from Settings > Apps > Apps & Features

Restart the computer and sign in

"Get" a new copy of the app from the Microsoft Store

Open the app > sign in using your HP Account credentials

"Add" your printer

Store - HP Smart - Updates

Latest version at this writing - just updated to 138.2.412.0

Manual App check / update

Open

Microsoft Store

Check your Library > "Get Updates"

Update (one at a time) any updates that are needed.

What about automatic updates for Applications?

The store used to offer settings for automatic update control in the app - a while ago, these features disappeared.

At least in Windows 11, the options (such as they are) have been moved out of the Store app proper and into the Settings for the application.

In Windows 11,

Open Settings > Apps > Apps and Features

Find Microsoft Store in the list of apps > Click to open Advanced Options (three vertical dots at right)

In Section "Background apps permissions"

Select which option you want  -- Not sure?  Click on "Learn more about the options"

Welcome to the HP support community.

I understand that you are unable to scan, I am glad to assist you.

Are you able to print from your computer?

If not, then uninstall and reinstall HP smart app on your computer to fix the issue.

Here are the steps:- Click here

If you are able to print and unable to scan, then follow these steps to fix the issue:-

Run the Print and Scan Doctor

• Download and run HP Print and Scan Doctor to automatically diagnose and resolve printer hardware and connection issues.
• After the Print and Scan Doctor opens, click Fix Scanning to test your scanner, and then follow any instructions to resolve the issue.

Check Windows Image Acquisition settings

• Windows Image Acquisition (WIA) is a Windows service that helps communication between the computer and scanners. If WIA is not activated, scan jobs can fail.
• In Windows, search for and open View local services.
• In the Services window, scroll down the list and find Windows Image Acquisition (WIA).
• Look at the Status and Startup Type values.
• If the status is Started or Running and the Startup Type is Automatic, WIA is running correctly. Skip to the next step.
• 
• If the status is Disabled or no status displays, right-click Windows Image Acquisition (WIA), click Properties, click the General tab, select Automatic from the Startup type dropdown menu, and then click Start.
• If the Start button is grayed out, go back to the Services menu, make sure Remote Procedure Call, Shell Hardware Detection, RPC Endpoint Mapper, and DCOM Server Process Launcher are running and set as Automatic, and then start WIA.
• Try to scan
