I have a xerox phaser 7300 the display is saying install or reseat cyan cartridge, yet i have taken the cartridge and the imaging uit out and reseated and it still says the same any idea ?

The Service manual says:


The Drum Phase Sensor for the named Imaging Unit indicates that the drum is out of position.


Initial Actions:

Reseat the indicated Imaging Unit.
Cycle the printer's power.

after these steps it gets a lot more detailed and you would need to be an experienced tech to understand everything and follow the steps within a timely manner, if reseating the cyan imaging unit doesn't fix the problem, then you will have to call for service.

Hope that helps

It is slightly unusual for it to be the black toner cartridge (usually cyan or magenta) but this issue is quite common on the 7300. You can find a lot of information about this here.

www.support.xerox.com -phaser 7400- support -fault code-941 says cyan or magenta toner failure, but the solution says to
1. remove & reinsert the cyan or magenta imaging units.
2. replace imaging units .
check out the site to see if helpful

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!

Hi.

Xerox says instead that the user should never used non original or refurbished cartridges, as in a number of cases this had been proven capable of damaging parts like the imaging unit.

I am sorry for Media Science, but they do not even have permission given by Xerox to build compatible cartridges (Xerox Corporation Filed a Patent Violation Lawsuit Against Media ).

Cartridges that have not built and tested with full printer manufacturer cooperation cannot be free of problems.

Also, I know that the 7300 is probably out of warranty, but using this cartridges on a new printer may invalidate the warranty.
Media Science does not make itself responsible in case one of their cartridge has damaged a printer.

My suggestion is to use original cartridges in future.

Best regards.

Sounds to me like you actually have the wrong part number. There are more than one cartridge for the Xerox printers, They have different chips on them. One is for billable accounts, one or more than one for accounts that pay for prints. There also was as i remember a spring type clip they left off some cartridges.
So with what you have tried and the old cartridges work fine, strongly suspect bad carridges.

Hi,
Sometimes on this machine as there is a lot of loose toner around it can cover over the sensors in the machine, what I would advise is to remove all the toner cartridges and check for the copper contacts on both the machine and under the imagining unit (which the toner is placed in). Once you have cleaned that away slowly close the lid and reboot the machine and it should return to normal. Its just toner getting caught up in the sensors. Follow the instructions below, when you remove the unit, lift it over your head to find the copper contacts and clean them, be careful not to spill toner everywhere. Good luck!

Reseating the imaging unit

Remove the toner cartridge:

1. Open the top cover.
   
   The imaging units are sensitive to light. Do not expose the imaging units to light any longer than necessary to remove it and cover it. Failure to follow these instructions may damage the imaging units.
   
2. Identify the color of the toner cartridge to be replaced (Cyan, Magenta, Yellow or Black).
   
   
3. Move the orange lever on the toner cartridge to the right so that it unlocks.
   
   
4. Lift on the back side of the toner cartridge first, then guide the cartridge out of the printer.
   
   
5. Set the toner cartridge on paper to avoid any toner spilling.
   
   Reseat the imaging unit:
   
6. Lift the imaging unit straight up out of the printer.
   
   
7. Line up the guide pins with the printer's frame and lower the imaging unit back into the printer.
   
   Reinstall the toner cartridge:
   
8. Install the toner cartridge by guiding the front onto the new imaging unit first then lowering the back.
   
   
9. Move the orange lever on the toner cartridge to the left so it locks.
   
   
10. Clean the LEDs with the supplied wipe.
    
    
11. Close the top cover.
    

Hi, Have you checked your cyan imaging unit?

Sounds like the yellow imaging unit it defective to be honest. I know its new, but may be bad out of the box.
