    Canon NP6050 Unit 1 paper jam

    The screen says "Pull out unit 1 and remove the jammed paper." The paper has the copy visible. It is lying flat but it hasn't entered the fuser. What's the cause and the remedy?

    Wow this is an old machine!

    Check no paper is trapped behind unit one, especially the rear connector block, only takes a small piece to cause this issue.

    Failing that then you will need to replace the fuser drive clutch or the drive gears may have broken also.

    What jam code? =^..^=

    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.

    No paper found. It never chewed up any paper, unit 1 just stopped working. It's been so long since I've had to access jam codes that I've forgotten how. Please tell me how to do that to refresh my memory.

    The problem is a rear broken upper fuser gear. Part # FS5-0379-000, 45 teeth.

    Apparently it is obsolete. Does anyone know where I might find one?

    This is year 2017 not 1988 ��

    Most NP are scrap metal.

    Just GOOGLE the part number :-))

    See links for part.

    I was able to get the part from CSI. I installed it and now the machine works fine.

    The challenging thing about this was that the cause of the malfunction was not immediately obvious. It was only after I found a small piece of the gear jn the mainframe that it became apparent. The remainder of the broken gear was still intact in its location, which is hidden under the the lamp cover.

    Good find, have seen many broken gear pieces.
