HP ENVY 4520 scan no finding computer anymore

[Steph007]

I used to scan no problem with my HP ENVY 4520 USB connected to a Windows 10 PC.

Today, it is not working anymore, when I click on the "scan" icon on the printer I get the message "No Computer Found", and then it asks to open the HP printer software, select "scanner Actions", and then select "manage Scan to computer".

What I have tried:

- I opened ENVY 4520 software, once in it, I can't find anything  like that. I can find a "Scan a document or a photo", but once I click on it, nothing happens.

- I opened the HP Smart App. I couldn't find anything like that either, and it says that "scanning is currently unavailable".

- I tried to close PC and PRinter, pull out and in again the Printer power supply, than PC restarted... no improvement.

- I have run HP doctor. It goes through the scan check no problem (I even hear the scan working). Clicking on the test button at the end... nothing happens. Trying on the PRinter, same problem.

I have tried about all the same serveral times, also with the printer in wifi mode, nothing different happens. I have tried the webscan, doesn't work either...

Help!

NB: the printer works fine in printing mode.

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.
