My Canon MF642Cdw has stopped printing the magenta toner and does a weird fade when printing Cyan. This started a little over a year ago, i have now been just using it for BW printing. I replaced all the toners back then and just replaced the Cyan and Magenta toners again today thinking the cartridges may have just been bad, but it is still doing the same thing.
Can someone please help me.
I have done all the self-cleanings I can.
