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.

The only way to reset the image unit drum is installing a new one. The new image unit has a fuse which once blown it resets the counter on the machine. You can call www.iteminconline.com I have their information in my ad place. They are good techs. I once called for a 7300 image unit reset and they said it was almost the same as a 2135 and they gave me this information. well goodluck.

37,0XX.xx Errors - PEST Faults
AC power supplied by power sources such as uninterruptible power supplies
(UPSs) or DC-to-AC inverter systems may not supply correct voltage to
properly power up the printer. Likewise, other devices sharing the same AC
circuit can cause AC voltage sags that cause the printer to fail its AC heater
PEST tests (Print Engine Self Test). The printer may produce any of the
following disconnected heater errors:
■ Printhead jet-stack 37,002.47 or 37,003.48
Error Messages and Codes
■ Reservoir heater, 37,004.40 or 37,005.41
■ Drum heater error 37,006.42
■ Preheater error 37,008.44
■ Ink melters errors 37,009.45 thru 37,013.40
The printer includes several heaters powered by AC. The printer itself can
power up despite insufficient or irregular AC voltage but it may fail its AC
heater tests. This is due the test not measuring sufficient current flowing
through the heater at the moment the test runs.
Devices sharing the printer’s AC circuit shared, such as a laser printer, a
coffee maker, or a space heater, may be placing heavy intermittent demand
on the AC circuit. This sudden inductive demand creates momentary AC
voltage sag that causes the PEST test to fail.
Verify the AC power source prior to troubleshooting these errors. For wiring
diagrams to aid in diagnosing PEST faults, see “Wiring Diagrams” on
8400/8500/8550/8560 PEST Description
37,001.46: Generic PEST error. Something went wrong during the PEST process.
37,002.47: PEST Error - Printhead Left jetstack disconnect. The left jetstack is
not drawing the expected power from the supply.

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!
