Over the course of a couple months I started having banding issues and started having trouble printing red and started getting mixed ink dropping in puddles and splatters on the edges of the media. When preforming a nozzle check I'm missing a lot of nozzles on each channel except one. After the issue got really bad I looked a little closer and noticed cross contamination in one Y damper, I replaced the dampers and still had cross contamination so I replaced the manifold which so far seems to have fixed the contamination issue in the Y damper but the nozzle check is still showing a couple lines of blue in one Y channel and the rest of the Y nozzles are firing blanks. The maintenance station is four months old and seems to be working like new. I was told that if it's not a clog it's the membrane inside the print head. Nothings clogged so it must be the print head?
