Got a brand new Epson cx8400 recommended by Kopykake, and bought their ink. Got empty cartridges on ebay. As yet have gone through a ton of ink and still can't get a good image, even if the nozzle check is ok--which is rare. There is always horizontal banding. The best result I've gotten still had thin black lines evenly spaced about every 3/4 of an inch. HELP!!!!!!
