we need to start an in-depth discussion on epson print heads.
1.ways to keep them going for years
2.ways to flush them, and with what?
3.ways to bring them back if they've gotten clogged
One of my main objectives right now is figuring out a way to keep a print head from ever going bad, if that's even possible. There are so many ways to approach it, can we come to a consensus on a straight forward approach?
hhahahaha, but seriously though. Deflection is just as much a concern as blocked white channels.  I often have deflection so bad the prints look like $hi*.  and the white channels are fine.  I often have a cmyk color go out on me before my white.
