lines across page

I have cleaned and aligned the print head several times, and the problem only gets worse. The issue seems to be with the black cartridge, and it doesn't start at the top. It prints fine for about 3 inches, and then there's a fine line missing all the way across the page. The line reappears at 1" intervals all the way down the page, getting wider with each repetition, until the last one is about 1/8" wide. The printout I'm looking at is the cover of a workbook I downloaded for a class. The center section is blue, with black at both sides and black letters in the blue in the top third and bottom third of the page. The lines appear in the black at the edges and wherever it happens to intersect the black letters in the middle, but they seem to leave the blue alone. I just changed out the black cartridge, but it was doing it before I did that, so I doubt that's it. Suggestions?
