    J2002 from LCT.....C654

    Anyone have a fix for this? Ive tightened the idler roller springs on the entrance door. Replaced clutches and rollers. Tried different Loop settings.
    If you run one page at a time it is fine. if you run more than that it jams.

    We replaced the whole feed assy on trays 1 and 2 and no more 2002s
    Seems it left the LCT ok but when it went vertical all bets were off.

    you will never believe what seems to fix it,
    i took the LCT and put it on a 654 and ran flawlessly.
    put back on 754 20-02...

    check this out, i installed a lighter spring to the sep roller assy and BOOM 2000+ pages no jams.
    if this holds up ill be damned.
    the LCT loop adj i do have at -9 as well.

    its timing. the sep roller cause the papers to drag screwing up the timing to the reg roller. it makes sense in a product flaw kind of way.
    anyway ill post back in a couple weeks if there are no more calls for j20-02!!

    We replaced tray 1 & 2 assemblies. Tray 1 & 2 right side door. LCT Drive Motors. LCT Clutches.
    Finally gave up and put a used LCT on and all is well. I wish i knew what it was but its not a problem now.

    I understand the product flaw theory on a new machine but mine has almost 7 million on it.

    By LCT I assume you are talking about the optional large capacity tray that mounts on the right hand side of the machine.

    Had this a few times, the soft gray transport roller after pickup in the LCT reduces in diameter as it wears and causes this exact issue. It is due to the resulting paper speed difference from specification and arrival time at the next point being late. When I've had this issue it is as much as 3mm smaller in diameter than the new one.

    Most prevalent on high volume machines, machines that use shit paper and especially in the case of A3 LCT's, machines that feed a lot of 100+gsm papers through it. I keep them in the car.

    If at first you don't succeed, try the way I told you how to do it in the first place.

    exactly, also the transport rollers up the side shrink with wear, you will see the problem happen in the fastest model in a given line first.
