With all the talk of how Epsons are always clogging, I feel I need to report on my own experience with my lowly 2200 (which I got when they first came out).
I print very sporadically. For a while a couple of years ago I was using third-party inks with excellent results (and no clogging). After one six-week trip to Italy in spring of 2006, however, the printer exhibited its first clogs. I did the head-cleaning (ink-drinking) routine a few times, then left it overnight and tried again. Byt the second day, the cleaning worked fine.
After that, I soon switched back to Epson inks (since Beluga caviar, which would have been cheaper, didn't give me very good blacks ).
Last January and February I was away (Death Valley, etc.) for over three weeks, and the printer came right back with no clogs after the trip.
My house is fully heated, air-conditioned, humidified, and de-humidified, so the environment is pretty good for the printer. So when this one dies, I'm very likely to get another Epson (probably the 3800).
As Mark Twain might have said, "You can clog all of the Epsons some of the time, and you can clog some of the Epsons all of the time, but you can't clog all of the Epsons all of the time."
