We got 2nd (Brother MFC-J5520DW); in the mail today; and tried once again to load (I-FAX) firmware; to enable "Internet-Faxing"... this second printer; failed just like the first once... I will not even bother to open the 3rd box; as will likely have to refund all three printers; and tell my clients; that this model-line is not dependable... We have been using Internet-Faxing with Brother-MFC for over 10-years and lately with HP-Models; so disappointed the this brother series/firmware appears defective... FYI: We depend on internet-faxing though www.RingCentral.com

Issues started about a week ago; since then order to more printers; for our family and clients...

On this 2nd-printer; we did the following on a "CLEAN-INSTALLATION" of Windows v7(x64)
1) Installed full-driver-suite (MFC-J5520DW-inst-C1-us1.EXE)
2) RESTART
3) Install I-FAX firmware using "BrIfax422.exe"; same failure as before...

Does anyone have solution or suggestion???
