I also have the Artisan 1430. After a couple of years (2-3) of use it started drying up and no amount of software-based cleaning would unclog the nozzles anymore. It's been a paperweight in my office for the last year or so. I have been contemplating cleaning it up myself. SeeI have heard this said and repeated many times. I'm possibly possessed of extremely good luck, but I've not had this issue with my Epson Artisan 1430 Photo Printer. I've let it sit unused for well over a year, and when I turned it on, it went through a cleaning cycle and has been working fine for the last six months of irregular and infrequent printing.
What's stopped me doing the cleaning work until now is the fact that I have not needed to print anything recently, and I don't want to have it happen again afterwards due to infrequent use.
