i think i damaged the damper or it was defective? i first tried to use the old magenta damper that i removed... it did help... maybe i didn't give it enough time? so i took the old yellow damper that still had yellow ink in it and put it in the magentas place and bam it printed all nozzle with the yellow.
so i did a inkfill per autographxx recommendation and the magenta printed. so either a combo of bad damper and ink not primed... but now it works.
