I was searching on internet and found a lot of informations about DX4 heads. It seems that DX4 head from Epson 10600 is the same head used on Roland and Mutoh printers. Also seems that head ranking isnot that important. Now price everywhere on line for roland and mutoh is $650 minimum. I went on http://www.nationalparts.com/parts.aspx?mfg=Epson and looked for epson stylus pro 10600 parts. I have found they sell printhead for $130 for this printer. Epson stock # for this head is F174010. I was wondering if any of you guys rvrt tried this. Manifold could be replaced for solvent inks. Please replay if you have any ideas about this.
