Ah, I do not have the FAX30 and do not intend to add one. I'll take that page out of the rotations.
I wonder though, this just pulls up a web page, yes? Might it be possible to have something else on the network present a page that the MFD could show in there? I know that'd be non-standard, of course, and not without complications and a lot of other setup to the device to get it to 'fake' being a Fax-30. But it'd be interesting to try...
