I put a CISS on Mom's Epson 730 because she prints every photo she takes or that family posts on Facebook. Yeah. Crazy, I know. But every few days, the lines have air in them and the cartridges don't refill and the prints are missing colors or messed up.
Why is this not keeping the lines and cartridges filled up? What can I do? I can't keep driving over there every weekend to prime the system over and over.
