Error message reads remove and check right cartridge
ANSWER : You can try cleaning the contacts on the back of the cartridge and the ones that they contact in the printer. Other than that, you have to replace the cartridge. I once had one that did the same thing. I swapped the cartridge with another printer of the same model and both printers worked fine. I swapped them back and the original printer got the same error. The other printer had no problem with either cartridge. I swapped them back and left them that way.
