A week ago my Epson 7800 worked perfectly, I made a dozen 17x22 prints. Today I went to do a nozzle check and, instead of the usual pattern, it printed two bands of dark stripes. I tried again with the same result, then turned it off and on, and tried yet again. Still just dark bands, so I tried to print an image. The entire sheet, except for the leading edge, came out completely black, dripping with ink, though I could just barely discern the outlines of the image under all that black ink.
Does anyone have any ideas what is going on? Thanks!
