I recently purchased 2 mimaki printers and am unfamiliar with the menu or the way they work. I need a service manual for a mimaki jv3 250 sp and a JV4 160. Not sure if any one would have one or if they even exist. I recently purchased 2 mimaki printers and am unfamiliar with the menu or the way it works.
