    Epson WF-7620 / WF-4620 THICK VERTICAL LINES error? How to fix?

    Anyone ever see this kind of thick-band, intermittant Printing Error pattern when printing? Epson WF-7620.

    Wiping rollers, and printhead cleaning & alignments do nothing (9 cycles). It seems like its printing very well but for some reason prints additional solid, controlled lines.

    This is very different from the scratchy semi transparent or variable width vertical lines created in other cases. Also, its interesting that its every color not just one color.
