Try running the gamma setup in service mode. I had one real strong on Magenta, ran the gamma adjustment and colors returned to normal.

It looks to me like the process colours are not quite mixing as they should. Its hard to tell on that image for certain.

I suspect they are printing to heavy paper stock and not adjusting the trays to compensate.

This is printed on plain paper and and the difference in colors is shown on all types of paper. If you see a picture where I show a little more detail what the problem is

I apologize for the spelling mistake :o

You could try tweaking the transfer voltages a little, reduce second transfer. The reproduced images appear to be blasting, which would suggest the transfer voltages are too high. It might even be an evironmental problem, such as too much humidity or lack of sufficient. What are the humidity sensors reading at?

Firmware could also contribute to this, ensure the latest firmware is loaded.

Replace laser unit. We had brand new C652 do the same thing.
