OfficeJet Pro 6978
Microsoft Windows 10 (64-bit)

I finally upgraded from Win7 to Win10.  My HP-6978 worked flawlessly with Win 7.  With Win 10 Pro, it prints fine.  But when I try to scan to Win 10, I get "Connection Unsuccessful -- The scan could not be completed.  Make sure the computer is connected to the printer and then try again."  My printer is cable-connected to the same house router that my Dell OptiPlex is connected to.  Anyone with ideas, I hope?
