Hi Jack,
I've just been reading through the previous pages, apologies if i'm repeating things that you may have done but did you have kb4557957 in the update history? I'd seen you'd tried uninstalling other kb's. Also i noticed your connected to the printer via WiFi and you can scan to the computer so it would look like a windows update issue! Is the printer near the PC and do you have "USB 2.0 A Plug to B Plug" cable you could plug in? Another thing you may have done. so apologies again if you have! Have you deleted the WiFi connection from the PC and tried reconnecting / setting up the WiFi connection again?
