Bizhub C451 covers sheet with a heavy magenta tint

Can anyone give me some pointers here . . .

This started out of the blue. I had printed a few sheets through the Fiery Command Workstation earlier without any problems and about an hour later this starts happening.

I have changed the Magenta drum as I thought it might be that but, it still happens.

Any help please.

can you send a picture. There is a small stick beneath the drum should be blue. You can try to pull it back and forth until you don't feel and pressure moving it and print a blank page if there is still color on it on places you will have to print a 50 pages and see if it fades. If it does continue till no color shows. Fixed my Yellow that way
