Just because the IU is not near EOL does not mean it is not defective, have you tested the cyan IU itself?
P-6 is cyan IU failure.
P21:Transfer belt unit/PH unit/Printer control board (PRCB)
Step Action
1 Wipe clean the surface of the transfer belt with a soft cloth, if it is dirty.
2 Change the image transfer belt unit if the transfer belt is damaged.
3 Change the PH unit.
4 Change PRCB.
(5 while you are there clean the IDC sensors too).

Start off with a reset and stabilize, then go into tech mode and print out a cyan gradiant page. Then print out a any one of the other colors, if they don't match I'd be looking into a new IU. Has this IU been chipped? After a while sometimes the chipped IU's will lose Dev and you won't get decent solids.
Report back.

Hello, call a technician to top or add Developer to that Unit and it will be ok, its cause by shortage of DEVELOPER

It is a two year old thread. I would hope he either has it fixed or replaced by now. lol

This is the second "developer epiphany" I have noticed--on posts that I have responded to over a year ago.
Got to love it.
