    c-6950 4551ci

    hi guys.

    TASKalfa 4551ci after switching on error c6950 appears.(also with cover open)

    24V on the IH pwb is oke.

    I already replaced:

    Low voltage unit (power supply)
    IH-pwb.

    Firmware update gives IH update error.



    Every suggestion welcome.

    thanks in advance.


    grtz.

    hi,

    2 possible reasons, check the feed pwb => replace
    another solution could be the engine pcb,

    have fun

    The IH board solved my KM-8001i. =^..^=

    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.

    Hello all

    Just got this code "C6950" on Friday on a Kyocera 3551ci and the machine is down, service manual states that it is an IH PWB failure and tells you to trace back starting at the Low Voltage PWB, then to Feed and Finally IH PWB . I checked Low Voltage PWB and got 118v and my Feed PWB checked out as well so I ordered the IH PWB. Went back today to install the IH PWB but unfortunately it didn't solve my C6950 , so I am going to try the white ribbon cables you referred to that fixed your machine, one of them is crinkled some. Will follow up and let you know what I find. Will probably bring a Feed PWB with me for good measure just in case my voltage readings were wrong.

    Thanks
