I have been having issues with missing nozzles on a Mimaki JV150-130 printer. I have replaced the cap and the dampers and done several ink fills, cleanings, and soaks. I can't get the nozzles to come back. I also have a magenta overspray issue. See the attached photos. I greatly appreciate any help or suggestions to help get the printer back up and running. I'm beginning to wonder if the printer head may need replacing.
