5ton 0 Posted December 28, 2015 A few weeks ago my Mimaki jv3 lost all its magenta ink overnight to the waste. I replaced dampers. Replaced the Capping station. Its still doing it. Now recently the black starting doing it today. What can be causing this? Is their a head height or capping height adjustment. I have the head set to thick.. Both the black and Magenta lines are on seperate pumps. I recently just ordered a pump but after the black did it im guessing thats not the problem. Share this post Link to post Share on other sites
