Hello Gary, CIS means Continuous Ink System (or Supply?). It refers to an ink supply system sold by MIS which replaces ink cartriges on Epson printers with larger bottles. Saves money on expensive small cartriges. There are several other brands (CFS - Continuous Flow system ?) sold by other vendors. I don't know all the names...perhaps someone else can list all the names, etc. There was a recent discussion on the merits of various systems. It would be nice to see a list of all the brands and brief summary of each. Regards, - cj
