    AR M277 "smeared/static" copy

    I have a customer who has a sharp AR M277. They called today with a copy quality problem.
    The copier is smearing the the copy. The image looks like it has been dragged, with wavy sides at about 2/3 down the (portrait)page, about 3 inches wide.
    I thought that it might be the drum blade. Replaced the blade, drum, and the developer. Problem still there. The developer unit has extra toner spray on the lower lip where the image is distorted after a few copies.
    I cleaned the coronas, and the transport section. I removed the tranfer and the main corona, individuallty to see is there was a difference. The copiers still appeared to have the problem in their unique way.
    Could it be a developer bias problem? Why only 3 inches wide and near the secondary mylar on the drum unit? Could something be shorting out? Should I replace the coronas?
    Please help.

      I would say either the mylars on the frame under the process unit, lower drum seal or developer seal. In this day & age, posting an image is always the best. Does it do it on self prints ? If it does, you've eliminated optics. If something is rubbing the drum, you should easily find the toner buildup on the offending item. High voltage arcing usually sounds like bacon frying & most of the time will pull developer or generate odd error codes.
      Hope that helps !

          There isn't anything that I can add to Tony's comments. We were just talking about this annoying mylar under the drum unit, and the upper developer seal can do the same thing.

          A common mistake is to install the new upper developer seal over the other one. It seems pretty obvious that those additional seals would start closing the distance to the drum, but I've seem plenty of machines with two or three upper developer seals stacked. And the yellow paper must be removed from the new seal. =^..^=
          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.
