Just had a guy bring this thing in for me to look at. When you turn it on all you get is a message saying none of the toners are installed. All the toners seem to be seated properly. When you navigate the menu to replace toner it says it can not rotate toner. It will also do some weird looking stuff in the display such as just cycling menu,yes selected, cyan toner missing, menu. Its just got a couple of bugs to it that make me think main board problem but thought I would give you guys a shot.
Thanks
