It's not "isn't open", it's "isn't open UNTIL..." - if you carefully
re-read what I wrote.

If you know the IP of your printer start a web browser and point it to
it. If you don't see the setup interface then I am out of ideas.

I need to access the "Remote Operator Panel", which is *deeper* than
the web interface. I can do almost everything routine with the web
interface, but not interact directly with messages on the printer's own
display. That is what the "Remote Operator Panel" is for - and this has
become important because of the fault with the display on the printer.

You are generally correct, but have not understood the specifics.

I have the same issue, I use the remote operator panel in IE11 with Java plugin. After you install Java, make sure you enable in IE11. It's slow, but works.
