Does anyone support or have experience with the Epson 7600 printers? My problem is: no matter how many times I clean the heads, my test patterns come out randomly worse or better. Occasionally when the test pattern is good the prints are fine. But more and more I cannot get a good pattern after multiple cleanings and I am wasting ink. Would the maintenance tank cause these inconsistencies -or- do the heads need some additional attention? Mark Knox 413 532 4316 (hm)
