You might want to contact this company. I've used their ciss and inks for several years now in my Epson Artisan 710 with very good results. They are very helpful.
I am a satisfied customer of LJH. Leonard went way out of his way to answer my questions. So I purchased a CISS for my Artisan 730 from him. One of the 6 cartridges was defective - he sent a replacement. May he live long & prosper.
