Welcome to the HP support community.

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

Check Windows Image Acquisition settings

Windows Image Acquisition (WIA) allows communication between the computer and the scanner. If WIA is not on or running correctly, scan jobs can fail.

• In Windows, search for and open View local services.
• Next to Windows Image Acquisition (WIA), check the Status and Startup Type.
• If the status is 'Started' or 'Running' and the Startup Type is 'Automatic', WIA is working correctly. No further action is required.
• If the status is 'Disabled' or blank, continue with these steps.
• 
• Right-click Windows Image Acquisition (WIA), and then select Properties.
• On the General tab, select Automatic from the Startup type drop-down.
• Under Service status, click Start.
• If the Start button is grayed out, return to the Services list and make sure the following services are running and set as Automatic.
• DCOM Server Process Launcher
• Remote Procedure Call
• RPC Endpoint Mapper
• Shell Hardware Detection
• Try to start WIA again.

I didn't know how to get to the Windows window for tasks, finally found it and local services, which did not list a WIA category. 

I am not computer savvy, but with a step by step instruction, I can get by. This remedy was not helpful, but thank you for trying. I may have to take printer and tower to the Geek Squad since I need my scanner to work.

PS ---Sandy:'

I went back and looked again, and I did find WIA. All the service status items were automatic and running, except the Remote Procedure Cal - there were 2 listed. One was automatic and running, listed as The RPCSS, and the other one was Windows and listed as Manual. The drop down on the Manual had an Automatic, but I was afraid to change it since the other RPC was automatic and I didn't know what the Windows one did.
