You do not have to use it in all heads, as Chris (Zoo) explains. Maybe, it's just that brand of ink. Chris mentions Filmdirect, and I've been using dye ink from inksupply.com for a couple of years with good results. I've just done this and except for a small firmware problem, it's working. Charlie Facini from AccrRIP is going to help me with that this morning. By the way, I bought my refillables from inkjetcarts too, but my cleaning solution and ink from inksupply.comSteve
Very interested in this thread. I bought refillable cartridges and ink from inkjetcarts a little while back and had the same experience as the OP. I assumed it was either a bead product or I did something wrong. I've been using Epson OEM inks lately as the cartridges I was getting from 4inkjets suddenly stopped working. I was actually just about to put a post up asking what everyone has been using or if there was a good bulk system I should look into.I use an Epson 1400.
