Colors printed incorectly on KM Bizhub C550

[itiswritten]

I work for a charity, we inherited a Konica Minolta Bizhub C550 which had been unused for at least 3 years. After some tinkering and the help of this forum I fixed a few problems and it is working great for most everything.

The problem I had came up when we were trying to print off some booklets, the color was off. When photocopying the same image it would come out fine. I tried printing it (and other images) on 2 macs and a PC, pdf or jpg, same result.

All the test prints in from the service menu seem to print nicely.

I have attached the image file and a scan file which shows on the left the print out in question and on the right a print out from another printer.

Any advice or pushes in the right direction would be greatly appreciated.

Thanks for all the help so far.
