I have had really good luck with InkEdibles cartridges. I had 2 Epsons before I finally bought a Canon. It has worked much better for me, but that might be in part because I print a test page with all 4 colors once a week. I think with the special ink that leaving these printers sitting unused for even a short time will cause the jets to clog. In the rare case when I get a small clog I use vodka in a syringe to flush the jets. Hope this helps a little!
