I have a bunch of MPC6000 and MPC7500 machines in the field - Each and every one of them had some sort of failure loading developer or setting up initial process control. That is a pitiful track record for setups, but once you go throught the bulletins to get the machine is running most seem to do O.K. - most common problems I have Black (or some other single color) will go light around 10-20k and be nearly impossible to recover without changing developer. This is a known issue if all steps of the setup did not finish properly, but these machines reported everything was good and ran for quite a while. These failures seem totally random and are actually getting kinda aggrivating.
Charge rollers fail and arc the drums (repeating dot all the way around the drum - almost looks like a perforation line)
Machine won't accept new toner after toner end condition - again there are bulletins about this happening if the initial setup is not done right, but these machines were O.K. and just decided to get bitchy. You either have to change developer or backup the NVRam, Clear the engine, and restore then reinitialize the process controls.
The PCU's are a real booger to rebuild compared to the previous generation.
Fuser life is better, but still doesn't really like heavy stock papers, and the exit jams are still a pain to remove sometimes.
I don't have enough High Volume MPC5000's to be able to tell you to go one way or the other, but it's generally not a good idea to push a color machine over it's max rating.
