Lexmark Scanners

I have several Lexmark x772 mfp machines that are dropping off the web interface; meaning, I can ping the printers and print to it, but the scanning function does not work. The web Interface doesn't display either. I have several of these machines in Georgia in several cities and they are gradually ALL having this problem.

Any ideas what ports the Lexmark scanners use?
