PRO-1000 Keeps Losing Gray...

Yesterday I experienced poor print quality and the nozzle check pattern showed GY was not printing. I did a Print head cleaning > Cleaning and the nozzle check pattern came out with all colors printing.


Today again I had poor image quality and again GY was missing from the nozzle check pattern. I then replaced the GY cart because it had been showing the exclamation mark for a long time. It appeared to be completely empty. I ran a print  and it was still bad. Another nozzle check pattern showed GY was still not printing.


I ran a second cleaning. The subsequent nozzle check pattern came out normal. I ran another print and it came out bad like the rest. Another nozzle check pattern showed no GY.


Note that the prints also had some horizontal lines.


I don't want to waste any more ink or paper. What is the next logical step?
