Alcohol and Q-tips, lots of them. One time I found an earring in the depths of the printer. Hmmmm. I don't really take the printer apart apart, I just open it up as far as I can & run the swabs over every surface that has ink on it until the swabs collect no more ink including on the jets which of course the manual says NeveR to touch. Ha. What have we got to lose? streaky printing, hopefully.
BJ, I've bookmarked a new Epson similar to one you suggested on Amazon. Actually, the "see newer version" listed is over $100 less expensive. I wish we could get high-capacity ink cartridges off Amazon. Is yours a wide format printer? That in itself is very attractive, as is Wi-Fi printing, but I just bought a whole round of cartridges for my current printer, which is only a couple of years old. I think I'd better use them up first...a few days at most.
