Extreme color problems with imageCLASS MF743Cdw


My printer started to get subtle streaks of color where it wasn't supposed to be, which I assumed to be a gradation problem. I ran the quick gradation auto correct setting, which had no effect, then bought paper to run the full gradation setting. After running it, prints had a strong blue tint to them, so I ran the full gradation correction again and it made no difference.

Any ideas?
