Scanner problem

[FMSFD]

My hp 6978 is connected by usb to my dell windows 10 laptop. Print and copy work fine. The scanner will not work. I get various messages but they all amount to scanner not available. I uninstalled the printer and reinstalled it and it worked ONE TIME. Five minutes later the app says "HP Scan cannot scan from this printer". I have tried the print doctor software but it freezes and won't complete the scan.

Hi @FMSFD

Welcome to the HP Support Community. I'd be happy to assist you with the scanning issue. 

Download and install HP Print and Scan Doctor, it is a Windows tool to fix printer issues. 

If the issue still persists, try re-installing the printer driver -

1. In the search box, type and open "Uninstall a Program".

2. Look for HP Printer software.

3. Right-click to uninstall.

4. In the search box, type and open “Devices and printers”.

5. In the Devices and Printers, look for your HP printer. If you see it listed right-click on it and choose “Delete” or “Remove Device”.

6. Open the run command with the "Windows key + R" key combo. 

7. Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”).

8. Click on the "Drivers" tab.

9. Look for HP Printer driver. If you see it Click on it and click “Remove” at the bottom.

10. Select Ok.

11. Select Apply and Ok on the Print Server Properties windows.

12. Close Devices and Printers Once the software and drivers are removed.

13. Restart the computer.

14. Download and install the software and drivers from here for Windows 10 (64-bit).

15. Click on the downloaded file and follow the on-screen instructions. 

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. 
• 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.

I have run the print and scan doctor repeatedly. I finally deleted the printer and reinstalled. The scanner worked ONE TIME after reinstall. Now, NOTHING WORKS. I have run the print and scan doctor again and according to it, there is no problem. I can't even print today. I need a way to actually communicate with hp support. This support situation is ridiculous.
