The Epson DX5 ecosolvent print head is used by Mimaki JV33 and Mutoh Valuejet printers. It is a new generation print head that allows fast speed, high resolution printing with ecosolvent or mild solvent inks. The Epson DX5 original print head is delivered in a sealed Epson package. This print head works with firmware up to 3.6. We recommend replacing the two head data cables together with the print head to avoid any problem (see product JV33 Head Data Cable).
