canon pro9000 color issues

[Sbbudds]

Have not used for a year,  had color print issues, so I told it to deep clean twice,  check heads.  still a problem, so I put in all new cartridge, every color except green (which I did not have on hand).   STILL color problems .  seems like the red and browns...   if I buy/change out the green will everything be ok.   ??

It appears that the image lacks magenta (which is the opposite of green).  So I'm thinking that magenta is thus the issue.

 I changed out all colors ink. Except green. Repeated Depp cleaning. At least 3 times. Still sane result. What else can I try?

Are the "C" and "M" supposed to be blank like that under the second column?   The colors also look a bit muted.

 I agree it all looks a bit light coloring and there's no coloring on that 2nd side Makes me really wonder since I put in new ink in hose slos . Kind of thinking I'm gonna have to just toss it I know it's old but lol it was a good priner once.
