imagePROGRAF Pro-1000: black turns grey

I am having a weird issue with the MBK. My prints are not printing the black and the black is turning into a faded grey. I cleaned the print head and the nozzle check print came out weird only for the MBK. The lines seem to be all aligned it's just that it is not printing the whole section so some parts are white. Why is this happening? 

I did a couple of nozzle check printing and initially it was spotty, then it came out how it's supposed to, so I printed my print. Which initially was printing the black perfectly, but as the print went on the black turned to grey. Checked the nozzle print again and it is coming out spotty again. I've dealt with this issue before, and cleaning the print head usually fixed it, but now it is not addressing it. Please help! 

 

another nozzle check everything is good except for MBK. The lines seem to be straight but the MBK portion doesn't print the whole time.another nozzle check everything is good except for MBK.

Forgot to mention that ink level is pretty full! so its not the ink level issue.
