I'm in need of one cap for the top of our ink bottles for our Mimaki JFX200-2513. We use LH-100 inks all except for our primer. The primer we're using is PR-200. The cap I need is the Cap B Assembly. The part # is MP-M014958. The only thing I have found online is sets of 8 caps, and they are quite expensive. Does anyone know of somewhere I can buy just one cap?
