I would say the best maintenance for any printer is simply to use it. There is nothing better to keep it from clogging than to keep the ink moving. A nozzle check pattern I don't think moves enough ink... you need to print at least an 8x10 with all the colors. I'm not sure how much ink your Epson uses for cleaning, but since you have to do some cleans in addition to your nozzle checks, I almost wonder if two or three 8x10 prints wouldn't actually use up less ink than having to do a clean. If I recall from my Epson 4000 back when I had it, a clean cycle would be around 10ml of ink, which is perhaps just over 1ml per color, but this equates to very many 8x10 prints that could have been done. Sure there is the paper expense, and paper is usually more expensive than the ink, but I still think its better for the ink to go onto the paper rather than into the waste tank.
