Have a look at this. Especially the part on t/c ratio. This is on the C250 copier, not sure how similar the printer is!

Definitely related to the cyan IU. Likely has failed. Replace cyan IU.
Hope this helps

You could have a failure in the print head(lsu). If in a humid environment fogged mirrors in the lsu can and will cause this. Also a bad motor for changing the angle of the mirror in the lsu.

Replace the cyan iu but if the problem comes back, replace the print head.
