Xerox phaser 7100 print color registration problems

SOURCE: xerox Phaser 6120 color problems

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.

Ik heb een deregelijk probleem gehad, ook bij merdere printers tegelijk. De oorzaak was achteraf logisch. We hadden een nieuwe zending briefpapier waar een bepaalde film op zat waar de printer niet tegen kan. Logisch, want het kan niet zijn dat alle 3 printeres tegelijk hetzelfde mankeren.
Ander papier erin. De eerste hoeveelheid zal nog problemen geveb tot der olletjes vrij zijn van de vettigheid.

I called Xerox and it seems that it's because the imaging unit is defective. They are seeding me one free of charge. Hope you can do the same...

First off on your screen access troubleshooting, and perform the remove light strips and also remove smears and skips.
Next go to Xerox.com, under support and drivers enter 8560 in the search box. then go to the support page.
You want to look up the procedures for TEC color correction. And follow those steps.
If you are using a generic ink then, all bets are off in getting true color reproduction.

Apparently, turning the unit off for 30 seconds, then back on will force the Phaser 7300 to do a color alignment procedure (according to Xerox support).

Then, if the problem persists, you are instructed to follow a very detailed troubleshooting procedure which I will leave with you in the following link:

I hope this helps!
