The paper is the same, Han. PhotoRag, and same batch. I used the same cartridges (carts) which I had in the 1400. they are old but the nozzle checks were fine right away. The ink is the same, Piezography Warm Neutral K6. Some of the ink is over 1 year old but we never had a problem with it before? I wonder if the files may have been corrupted transfering from the PC to an external drive and then to the Mac. Thanks in advance for any thoughts.
