I played with CIS systems for a few years. With Epson 1160, 870, 2200 and 1400 printers. Still have a number of bottles of ebony ink frim MIS and syringes and cartridges, etc. Such a PIA. But I stuck with it for many years and through 4 printers. Got some decent results but not always. Gave up after that last clog when I really needed the printer to work and the clog just kept coming back and ruined so much paper. No more. Love my 3880 now and will not go back.
