I have an ADV5030i that continulay reboots. You can get an odd copy out or PG/P-PRINT but then it will reboot. You also can't print to it. The monitor will say "Processing..." then "Waiting to print...." this will hang at this all day.
I've swapped the MN1 and system software update and MMMCON cleared it. The other MN1 doesn't reboot as often but it still wont let you print.
Hope someone can help
