got the 8860 mfp delivered few days ago. Can't get it to go online. We've tried reinstalling both the PCL & post script drivers. We can ping the printer and access the centreware IS, but can't print at all. Called xerox, was told to "drain" the printer by turning it off, removing both the power and network cable, then turning it on and after it's ready, plugging in the network cable. That did not work at all.
you need a new firmware, call xerox to obtain it :
