Won't print we replaced the imaging unit and because of an error message and now it won't print new documents just old ones over and over

When you get the error message "Replace imaging unit, 0 estimated pgs remain [84.3x]" This means the imaging unit has reached end of life and needs to be replaced. The device will not print, and this message will not be cleared, unless you replace it with part number 50F0Z00
(or 500z)
Vertical streaking. If the imaging unit is near end of life, or the device has had problems with non standard toner, vertical streaks may occur on the page. Replacing the imaging unit will resolve the problem.
Vertical streaks on page
Vertical band at top of page. This typically appears on printed images, but can also appear on text. The most likely cause is toner contamination on the charge roll, however if the band is still visible after printing 30-40 continuous pages this means the imaging unit needs to be replaced.
Vertical Banding on images
Seal failure on the imaging unit. Occasionally seal leaks have been seen from the Imaging Unit.
Toner will be seen on the main frame near the Imaging Unit sides.
If toner build up is excessive, it may even fall into the Tray below. Cleanup with a toner vacuum may be needed.
Replace the Imaging Unit to fix the problem.
Spots, scratches, marks on the page. If they are random, this indicates a problem with toner scatter.If they are repeating patterns, measure the distance between matching marks or spots. If the distance is one of 97mm, 47mm or 38mm, this indicates marks or dents on the imaging unit and it will need to be replaced.

Dear Diogo,

This error message occurs when the print head life is over. Every print head is designed with a specific life time (it is purely a mechanical device). Once the life time is over you will get this error message.

I recommend you to calibrate the print head, if you have that option in the software or front panel display(if any). Also, you can try using a new set of cartridges (if you printer is ink jet)

Thanks and regards,
Dr Tony.

Nancy, Your imaging unit has a limited lifecycle. Documentation states that it can make 24,000 B&W pages and 6,000 color. The message is telling you that you are getting close to that limit. Eventually you printer will stop printing, and your messahe will state "Replace imaging unit". This can be done by you. It is very easy to do. The imaging unit is fairly expensive: around $150 or more depending on the merchant and shipping charges.

Printer needs a new drum unit (imaging unit). Replacing it will either automatically clear the error (and reset the counter for the imaging unit), or there will be a set of reset instructions provided with the new unit.

These units are automatically reset with a fuse. When you put the imaging unit in it will completes a connection which resets the count then simultaniously blows the fuse. Sometimes the fuse blows before the reset, which is what it sounds like happened here. The machine should print normally but the error will persist until the unit is replaced with a new one. Is the the imaging unit an OEM unit or remanufactured? Whoever you got the unit from should replace it as defective free of charge. If it is OEM you might have to go through Xerox to get it replaced. I don't know if the Big Box stores will.

Complete the following instructions:

1. Power off your All-in-One.
2. Use both hands to lift up the scanner unit until the scanner support holds it open.
3. Turn the All-in-One on. The print cartridge carrier moves and stops at the loading position, unless the All-in-One is busy.
4. Remove the color print cartridge.
5. Lower the scanner unit until it is completely closed.
6. If the error message reappears, replace the black print cartridge with a new print cartridge.
   If it does not repeat steps 1-3 and then go to step 7.
7. Reinstall the color cartridge and remove the black print cartridge.
8. Lower the scanner unit until it is completely closed.
9. If the error message occurs again, replace the color cartridge.
10. If an error message reappears, repeat steps 1-3 and reinstall both print cartridges.
11. Lower the scanner unit until it is completely closed.
12. If you receive the error message again, replace both cartridges.
