my HP scanner won't connect to my computer. Printing is fine.

[MareTrotKell]

Color LaserJet Pro MFP M281fdwscanner has lost connectivity to my computer.  However, I can still print.  when I use the HP scan doctor, it tells me it can't find my computer via wireless network, but it obviously can as is connected because I can print to it.   Won't let me download drivers.  I've done everything but uninstall and reinstall.  any suggestions?

Welcome to the HP support community.

I understand that you are unable to scan, 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.
• In Windows, search for and open View local services.
• In the Services window, scroll down the list and find Windows Image Acquisition (WIA).
• 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.
• Try to scan

1.  Printing normal does not work, but printing 'Best' is light, but works.  I went through three levels of cleaning and it did not improve.

2.  I tried scanning several pages yesterday and the HP7640 All in One, scanned two and stopped scanning.  I get a message 'Cannot find HP 7640.'

New clj479fdw, print is easy set up, scanner doesn't work. WIA on and reinstalled, firmware & software downloaded and installed, properties set, wifi on, just keeps saying it's not enabled (it is). Scan doc says Device mgr error (but no #). 3 hrs spent on this. Device is updated. 

Also, you're WIA msg if it says enabled, "go the next step" but you don't say a next step. I'm out of ideas. Reinstalled THREE times. About to return the thing. Help.
