I was wondering, does IJM sell storage cases, for extra sets of carts? I have an Epson R3000, that is currently filled with flushing/storage carts. I am getting ready to install a new set of carts with Cone inks. So, I was wondering, what is the best way to store the Piezoflush carts that are currently in the printer? As I asked earlier, does IJM sell cases for such storage?
