So I recently setup a brand new Epson 1430 with the PiezoDN CISS. My nozzle check with the epson inks was perfectly clean. I followed the instructions on the CISS and the nozzles clogged immediately. It took seven cleaning cycles to achieve a clean nozzle check. After a week I noticed air in the CISS tubes and the nozzles were once again clogged. It takes me several cleaning cycles or printing multiple prints before the head is clear of clogs.
I have the CISS sitting up on the box it came in. Does it need to be higher? It’s kind of a bummer as I haven’t made a single neg yet.
