I do believe you can change the manual gamma settings for just the cyan to tone it down cause it is stronger than yellow and magenta since you just changed it.
Or access service mode and tone up magenta and yellow and then perform engine color calibration.

Not uncommon for toner hoppers augers(doesn't really have a pump as such) to foul up and not drive toner to the pcu.
good luck changing one of those... lots of fun
