      I have seen this several times before, and I believe that your charge corona is arcing to the drum surface.

      This could be caused by several things:
      -broken CC assy (grid is loose)
      -worn drum shaft (s)
      -bad DS rollers in the DV unit. <-Most likely

      There is a mod available for the DV kit which replaces the all plastic DS rollers with a bearing roller.
      Part #A1UDR90100
      The kit includes 2 new DS Rollers as well as some new style spacers and end bushing for the mag roller

      Hope this helps

      Trevor

          My guess is replace the developing unit, along with the developer.

              Drum arcing to: a) grid, or b) developing roller. =^..^=
              If you'd like a serious answer to your request:
              1) demonstrate that you've read the manual
              2) demonstrate that you made some attempt to fix it.
              3) if you're going to ask about jams include the jam code.
              4) if you're going to ask about an error code include the error code.
              5) You are the person onsite. Only you can make observations.

                      Is the drum scored in the right side where the white trans roller finger contacts it? Are there upgraded dv collars on mag roller? Is the mylar torn at end of mag roller? How old is trans roller? You can take some, not all shims out of trans roller to prevent scoring, especially on rear side. New dv unit is about $100 + dv. Drum r/b kit & new t. roller & done for under $200.
