I had a really old epson, and the alcohol trick worked twice... after that.. i could have tried removing the print heads... but i had no idea how to remove the casing w/o destroying it... it seems to be sealed or something.
But i didn't try for long, cause it wouldn't be worth it as i got an HP832 for $100 shipped (ah, the good ol' VA days ). Any of my friends w/ epsons haven't really hit a clogged print head problem like me, but everything else.. noise, constant self cleaning... just no good IMO.
