    [CQ] 6551ci streaking and offsetting in fuser

    Don't have any samples to post but we've got a classic fuser temperature problem, streaking and offsetting. Starts happening on color images (not necessarily pictures) and then of course continues on anything else. It will clean up but it takes a while.

    Here's what we've done:

    Replaced the fuser (a couple times).
    Replaced the IH Unit (used with only 300k on it).
    Replaced the Front PWB since it controls the IH motor and core sensor.
    Firmware is up to date.
    Played with fuser temp a little bit, pushed up 5 degrees (always hesitate to get crazy on this).

    When we replaced the IH Unit, it did last about 24k prints (7k color) before they complained of it again.

    Color count is only 160k but the machine is more than 6 years old with 2.3 million total on it. It's never had a Maint. E kit done on it. Could it be some sort of overtoning in the colors?

    We've metered the power outlet but we don't know what else could be on the circuit.
    We've metered the IH PWB but don't know if it could be an intermittent issue on that board.

    Has anyone seen anything like this that wasn't fuser or IH? Any ideas what we're missing?

      Two very important items I don't see mentioned:

      1) What media type (in gsm please), and what media type settings?
      2) Is it OEM toner?

      =^..^=
      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.

              1. It's 74 or 76 g/m2. Media type is Plain which is set to Normal 2 which is 74-90 g/m2.
              2. Always OEM toner.

              An update, after my 1st ​message, it was decided to do a Maint. E and it cleared up. For how long? We shall see.

                  Kyocera recommends to have this model put into silent mode to solve this issue.

                      Would you happen to have a link to that? I've searched a long time and can't find anything on Astea or anywhere else frankly.

                      Thank you.

                      edit: Guess I'll go search Astea for the model and silent mode.

                          I know. They hid it under "toner stain". Or search D098

                              Thank you. I did finally find it. Guess now I have to add "toner stain" to my list of words to search. I hate Astea. I like their Service Navigation tool but they are much too slow updating it. We should be able to search for bulletins by model, like you can with Sharp (and probably other Mfrs too).

                              Anyway, we are going to try that as well. Thanks again.
