printers black color prints fuzzy

I have cleaned it, aligned it and it just wont print a vertical line straight. It seems the heads are not aligned, but I cant seem to do anything to correct it. Color prints out quite nicely.
I believe I had this problem years ago on another epson, but dont really know if I had found a solution.

Already did, several times.

Refilled, but I have done this for years so I dont see a problem.

Just refilled it.

Doubt it, since the print head is not on the cartrige like a lexmark would be. I may just buy a new black to see if its actually the problem.
