My R3000 has been sitting idle, with Piezoflush carts, for a year. Now, I am planning to resume printing, with a fresh set of Cone inks and carts. here is my question: I never use the matte black ink. So, would it be a good idea to leave Piezoflosh in that line, until I actually need matte black?
P.S. A little off-topic: Does anyone know if there are any upcoming discount coupons on ink sets? I have seen discount codes appear on this forum, from time to time.
