My printer prints, but when I try to scan, it says I need to set up. It was scanning before.

Welcome to HP support community.

Check Windows Image Acquisition settings

• 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.
