Xerox 7500 cyan blurry

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.

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.

In the Phaser 6250 Color Laser Printer Service Manual (which I had to have emailed to me from my toner supplier since it is not available to the general public) I went to Chapter 6 - Error Messages and Codes. I had to reboot the printer. Here is the procedure.

Entering by rebooting the printer:

1. Turn the printer power OFF
2. Hold down the Back and Information buttons simutaneously and turn the printer
back on.
3. Continue to hold the buttons until the following message is displayed on the front
panel: Service Diagnostics V#.##, Initializing ....., and then release the buttons.
4. The front panel displays the Service Diagnostics Menu.

On the display is a menu. Find Transfer Roller. Press enter on this menu where it says Toner Waste (Not Full). Back out of the menu.

All of a sudden the machine came to life. You may have to turn off the printer and turn it back on again.

Good Luck

Resetting Transfer Roller Life

• Resetting the transfer roller life is to be performed only if the Transfer Roller Assembly was defective and or the assembly is replaced before an end of life or near end of life message. Not to extend the life of the assembly. Doing so may cause premature failure of other internal printer components.


• The printer will prompt the user to reset the life counts if the assembly is replaced after receiving a Replace Transfer Roller or Replace Transfer Roller Soon message.

1. Press the cancel button several times to flush processing jobs from the printer.


2. If you do not receive access to the front panel menu by doing this, power off the printer and disconnect Ethernet, parallel or USB cable from the printer.


3. Turn the printer back on, and while it is powering up, immediately start pushing the cancel key repeatedly until you receive access to the front panel menu.


4. If the printer menu appears on the front panel screen, follow the instructions below to reset the Transfer Roller life if the printer did not prompt you to reset it:

1. With Menus highlighted press OK.


2. Press the Down Arrow and scroll to Supplies Info Menu.


3. Press OK.


4. Press the Down Arrow and scroll to Exit at the bottom of the menu tree.


5. Now scroll up to Reset Transfer Roller Life.


6. Press OK.


7. Reset Transfer Roller NOW is displayed.


8. Press OK to reset the transfer roller life.

Hi clwest: I hope that this will help you.

Transfer Roller is at End of Life
■ Print the Supplies Usage page to verify the remaining life and Transfer
Roller install date.
■ Cycle printer power.
■ If the problem persists, follow the procedure below
Note
Look at the clear plastic window on the Transfer Roller. If toner is present in the
center of the window the Transfer Roller is at end of life and needs to be
replaced. If no toner is visible, try cleaning the CTD (ADC) Sensor.
The “Transfer Roller is at End of Life” is a warning. “Replace Transfer Roller” is
a hard stop.
