Not printing cyan on xerox 6360

SOURCE: the black print jobs have a shadow about 3 inches down the page

I had replaced the fuser - no improvement. I removed the fuser, imaging unit & transfer roller. CAREFULLY using a vacuum cleaner I cleaned all units and the internals of the printer, rotating the roller on the imaging unit to clean all parts. (Warning Place Imaging unit on paper as toner escapes) After a few test prints the page cleared and duplicate ghosting cleared.

I have had to repair a few of these. Take off the sides and back of the 6360. You'll see the hoses that feed into the laser. The black one becomes unplugged from the laser. All you have to do is plug it back in. The next step can be kinda messy. Take out the black toner cartridge, and spin the motor backwards. You'll know you're going the right way because it won't turn the other way. Cycle the gear where the toner sits for about 2 revolutions. Reassemble and you should be good to go!

This thing took me 6 days to figure out the first time. Haha!

Please vote on my solution! Thanks!

I am running this one and I perplexed by what your saying.
Although I will offer some ideas.
I am running through my mind why the label would only affect the colors.
So some of what I am saying here is thinking.
That is a carousel color printer, and the label is confusing me, mainly since you said black is fine.
I can understand one color being off with the third party toners, but not all 3.
What you are having in some way has to be a contact issue, as if a piece of the label would up on a ground contact.
I would first try removing the transfer assembly, all the toners and the imaging unit, and carefully inspect for another piece of label.
Look at all the metal contacts on the cartridges and internally to the machine, see if one is dirty or somehow bent.
Go into you menus and run a color calibration series, and also do a memory clear, and NVM/NVRAM reset. But before you do any resets print out a configuration page to confirm your addressing if your using an Ethernet cable.
USB wont make a difference.
The reason I suggest the resets and calibrations is the label could have caused some high voltage arching and therefore corruption.
But, then again, why wouldn't that affect black and white. What does black graphics look like?
This one is making my mind spin.
Calibration makes sense because you say you have wrong color substitution, yet doesn't address streaky appearance That to me suggests a bad ground contact, But why only bad in color LOL.Ahhhh you have me nutty with this one. LOL.
I keep migrating back to software corruption or mis calibration.
Let me know if this makes sense or helps. Reading your problem makes me want to see this one.
Anyhow let me know if my rambling, which is rare helps.

In all honesty, I suspect the print head has some bad jets on it.
Xerox will not warrany it since there is the presence of non xerox ink in the print head.
When you have tried as much as you have with the maintenance cycles. I would suspect a bad printhead.
When the jets become blocked to the point where you cant get all the colors sprayed onto the drum, you get mismatched colors.

the problem is not with the printer but it is with the ink that might be damaged, this is located inside the printer
