How is it written on the machine's nameplate?
AFAIC, that's the
correct way it should be written.
< OT: rant > If it's officially written in all caps, then I * might *
mention on the first reference that the vendor did so, but only if I can
think of some reason why my readers needs to know. In all subsequent
references I'd write it "correctly". I simply refuse to be a party to
any company's marketing. As far as I'm concerned, "marketing" is just a
business word for "lie." The reason companies put names in all caps
even when they're not acronyms is so the names STAND OUT on shelves and
in the press. That goes against my job, which is to tell the truth or
as close as I can get to it. < / OT: rant >
