Riverswild is right. Genuine Epson ink will clog just as well (or badly) as the generics. The problem that I have discovered with Epson is that they are one of the only printer manufacturers that I'm aware of that when you replace the ink cartridge you aren't replacing the ink jets with it. That causes a problem over time, as I've discovered.

My grandparents just inherited a Stylus 740 though a relative's upgrade, so I'll just give these carts to them. Thanks all.
