Thanks for the update! I have an old Windows XP laptop which I use when I want to scan and send something. It does not use WIFI to connect to the printer unit (It uses a USB cable). It definitely is a Windows 10 update that is causing the problem ...
Similar error on a MG3600 printer. Windows 10 laptop. I tried using a direct connection to the printer via USB and it did not help. I would hate to have to stop using my scanner.
