Not unbelieveable at all. I've cleaned up a lot of Epson (and Canon)
printers.

Um... some? 3? A furlong? How do I quantify it?

Not just on power on/off.

Have you tried SSC Service Utility to try and reset the ink chips?

You can inject a little cleaning solution (not straight IPA) into the
cartridges, but it isn't easy. Epson has gone to great lengths to
prevent refilling.

Better to buy a cheap set of 3rd party cartridge. These will be dye
inks, which is actually better for cleaning.
