    iRA 7065. Cyan streaks cross feed. New drum, developer and ITB still there.

    Having trouble getting rid of this cyan streak that runs opposite the paper feed direction. New developer, new ITB belt, new drum and it persists. Only seen when cyan is being used on a full feild. Shows up more pronounced on heavier weight paper. The streaks are about 4.75 cm apart from each other.

    Attached is a scan of the issue.

      Looks like Pitch Lines /
      Try swapping the cyan and magenta developer stirring motors
      or Try replacing the Drum Drive Assembly (FM3-4727-010 - Y/M/C) for Cyan
      or Check and swap the laser units ?

      or Try swapping UN41 (Developing HVT M) and UN42 ( Developing HVT C) / see if M displays issue

          Swapped things around for except drum drive assembly with M and problem stayed with C. Noticed cyan color registration is also shifting in and out on a single a printed sheet which makes me think it is going to be the cyan drum drive which has been ordered.

              Drum drive assembly fixed it!!!

              The bad one looked visually fine, i couldnt see any damaged gear teeth.

              Thanks so much
