Idololab, I think you are right. I'm not sure how but my print quality seems unaffected still. I even printed several green purge patterns, of solid #008000 green, around 6" x 22" areas. No lines, stripes, or any other problems in the blocks. Weird. I guess I will go ahead and get a new printer since epson instant rebates expire on 1/31, but I suppose I can continue to print until problems start to show in the prints.
