    [Jamming] c6501 when duplexing creases paper pre image transfer

    Hi all
    Is it too late to say Happy New Year??...

    KM c6501 - Year: 2007 Count:3.8M Maintained: Service contracted until 18 months ago, resurrected last week after dormant for 12 months. Simplex is fine

    See image below...
    When duplexing, as you can see, for want of a word it is creasing an inconsistent 'z' fold and is pre-image transfer, at what stage in the ADU I don't know.
    I must have killed too many brain cells over the festivities as I'm scratching as to where to start.
    In my mind it is mechanical...

    So any pointers, starters for ten, link to relevant posts most appreciated.

    Thanks
    Mark
