Did you run your drop position correction alignment? Looks like the bi-directional alignment is off. If you're printing uni-directional, it's more likely a physical alignment that's off. Did you just change the head?

It's possible the cams that hold the head down are loose which would allow the head to slowly move out of alignment. I can't think of any other way that pattern would happen other than that as long as the bi-directional alignments are in line.
