HP Scan not working for MFP 126a with Windows 11

[HCDEN]

My recently purchased 126a printer's scan PC function (HP Scan) is not working with the latest windows 11 update. It only works when I uninstall all HP printer drivers and re-install them. Eve then it works just for one session. When I have another scanning task, it displays the error message: scanner communication cannot be established.

Please assist.

Welcome to the HP support community.

I understand that you are getting a scanner connection error, I am glad to assist you.

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.

1. In Windows, search for and open View local services.

2. In the Services window, scroll down the list and find Windows Image Acquisition (WIA).

3. 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.

4. Try to scan. If the error persists, continue to the next step.

All the services that you mentioned were running, but the scanning function didn't work.

The RPC was Running (Automatic) but the RPC Locator wasn't--so what I did was-- turned on the Remote Procedure Call (RPC) Locator and the Scanner started working again.
