Please see attached 2 files (hopefully that works ok). The first one is the original nozzle check done a week or two ago, the second is the one from today, #19, and I have 17 more nozzle checks in between these two. I'm refilling OEM carts with PC inks. This is the first problem ever with this printer. What I've tried so far: Cleanings, no more than 3 or 4 in a row. Deep cleaning, just one. A couple of Qimage's unclog pattern. It appears to me the only thing that has changed after all this is it looks a little worse now than it did to begin with. Maybe I should have just ignored it and it would have cleared up on it's own.....? Zooming in on the white band in the BK shows a weird pattern, I've never seen something like that before.
