All my imgaes seem completely over run with Magenta. I have cleaned everything possible, even cleaned out a whole load of excess magenta toner.
The black also seems to be fading on the left side - but maybe that's magenta related too... who knows... at my wits end. This just started out of no where

Dirty mirrors will gives you dull color images..It seems color combination faulty..
chk original cartridges installed? or refilled cartridges?
Take supply status page..
chk colors..If color is dull(light) clean laser scanner assembly mirrors.
Do the color calibration..
Print from other file..
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.
The following may work: remove all the ink supplies. Remove the printhead and soak it for about 5 minutes in 0.5" of very hot water. Gently blot the printhead on a soft damp paper towel to remove the excess water, then replace in the printer and then reinstall the ink supplies.
Have you tried running head-cleaning cycles? If not, try 2 or 3 followed by a nozzle check and see if magenta starts to appear. If this still produces no magenta print, or you've already tried this with no success, report back.
My first instinct would be to call the people who serviced it and have them check it out for you. If you don't have time for that then the next and slightly more expensive solution is to replace the magenta toner cartridge. My reasoning for this is if you get them to come out and explain that it is since they cleaned it then they can pay for the replacement cartridge, or clean it again. But I think that if the new cartridge does not solve the problem, then during the cleaning the tech made a magenta mess somewhere in the printer. I hope this helps.
I am going to answer this even though there was no reply to my clarification report.
No, it is not a HVPS problem. This is a magenta developer problem. The magenta developer for some reason has the highest failure rate of all the developers, including black. Perhaps because there are more shades of magenta in color prints.
Since you changed the toner, we can assume you are not out of magenta, but it is possible that you did not run a developer cleaning in the maintenance mode on the magenta developer.
If the magenta toner had been allowed to run out all of the way, a developer cleaning would allow the toner auger to move fresh toner from the toner dispenser, through the feed tube, into the developer.
If you have run the developer cleaning, and you can see that there is magena toner on the magenta developer ( for clarification, the developers are located behind the imaging drum. remove the drum to expose the 4 developers ), then the developer itself is defective.
We have over 50 of these printers and a few have had the magenta bleeding problem. On everyone of them the problem was corrected by going to the clean developer function under Maintenence from the Menu and choosing to clean the magenta color. Usually have to run it a couple times but it has always corrected the problem so far.
