As I mentioned in my post on 8th June, Epson have admitted that their scan software does not work properly with W 10 version 1803, they told me over 1 month ago that their highest technical department in Japan were working with MS to work out a solution to the problem. They are certainly taking their time!
As reported here some users found reinstalling software or running as Admin solves the issue but I can tell you none of it works with the Workforce WF-7610! Only option is to revert to 1709 (if you can) or use 3rd party software until Epson issues a fix! Windows 10's built in scan will work but it's very basic.
I just wish Epson would get a move on, everyday I check the website looking in vain for a new driver which never appears.
