I happen to read your question and only want to say, that I also have a Xpress M2070W and this multiprinter is working 100% for me now, everything works fine (print, scan, copy).
I use Easy document Creator version 2.02.53 (2018-05-24).
I also use another scanprogram that is named NAPS2.
That scanprogram is also working 100% for me.
I use Windows 10 Pro
