    [Electrical] Bizhub C452/ NEC IT45C6 Image Problems

    This machine produces bands going through the image on full color copies/prints, I don't see it on copies with 10% color coverage. So far I've changed the transfer belt, transfer roller and fuser. Removed and cleaned the LSU assy and replaced the MFP pcb and installed new firmware with no luck. The image shows up on the paper at the transfer belt. I have not replaced the IU's because the lines are consistent through each color, any help will be greatly appreciated.

      I'd be interested in seeing a scan. =^..^=
      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.

        I have seen IUs cause problems for the preceding colors, since black is furthest to the right it can cause issues for the other three.
