Rafe, I'm with you on this one. My recent dissection of a 5 color Epson cart allowed me to better see what goes on - with the sponge in place and the chamber filled with water the exit port doesn't drip - take the sponge out and it drips slowly, but steadily. If we could find a replacement cart with a removable lid, I'm sure we could come up with a sponge arrangement that works as well. If you had a piece over the filter and another horizontal piece stuffed into the top leaving a small area of liquid ink under the sponge top I would think this would work. The sponge top would keep the ink from splashing out and the piece over the filter would control the flow rate (hopefully) and there would be liquid ink that could be topped up without bubbles and could soak into the sponge at it's leisure. This is an obvious case of who benefits. Cart and ink manufacturers are not going to produce a multi, multi, multi use cart - why would they? That might give us CONTROL and they sure don't want that. Why doesn't everyone on the list who is seriously interested in this issue make a concerted attempt to design a prototype cart that works and has innards that we can get at easily. I can't believe with the talent on this list, it can't be done.
