Bob, The inconsistencies of the Piezo ink may relate to the use of a CIS. If that is the case, it might be a good idea to take some ink from the 7000 carts I got for you and see what they look like. Those users are probably going to be the most critical of any density differences any way. Is it possible to pull a couple of ounces out of the carts for testing? Paul
