you will need to call Xerox I guess, every thing you state applies to the General release firmware available on Xerox.com, and it was all fixed in the spar version I actually linked.
The only other place to look is the printers own hostname.
When you call Xerox though, have the Wireshark trace of the attempted scan to supply them and a pdf copy of the configuration report from the device (So they can use that to cross reference the network traffic in the trace)
