Magenta background across the entire page that fades in from lead to
trail can be caused by a failing HV1. Please replace HV1 (p/n A00J M407
01) to correct the problem.

Since you have Cyan toner in places where it should not be then the only possible cause is a defective Cyan Toner cartridge. I worked on one just last week where the customer complained about Magenta toner on their prints. I also noticed Magenta toner on the Transfer Belt just as you see Cyan toner on the Transfer Belt. I replaced the Magenta Toner Cartridge and everything cleared up nicely. The Transfer Belt Unit can also cause similar problems but it would not be ONLY one color like Cyan. It would be a mixture of all colors. My bet is replace the Cyan toner and you will be fine. If you have an old empty one just shake it up a bit and try it as well. This might allow you to verify before buying a new cartridge.
Good Luck and Thank You for using Fixya.
