That is really old firmware, in fact it is 10 versions behind, which in itself isn't bad, they only update when there is an issue, which at a time there was because the one you have is a spar version, but there was a newer General release that should have been installed, but at this point, as there is an issue, you might as well go to the newest.
Iif you can't do the update I would have your IT call Xerox or just update it themselves.
