    Here's is the one from the 2550ci. This thread saved me some time. I thought it was a belt issue, as you can see the motor turning, but the belt didn't turn once installed. AndyF's description is what I experienced.
    Thanks !
    Hope that helps !

I have checked the flat ribbon cables on the engine pwb and feed pwb as we had a previous case where the flat ribbon cables were at fault.
    Ive been told by tech support when the fuser is going bad and temp drops the machine jam at reg roller every time i didnt hear about the z fold though

    Thanks Tony. I expect to see that one again.
    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.

    jam 4101, jam4111 ---> duplex clutches, there is two in the rear of the conveying unit, one at the top and one at the bottom each one gives one or the other jam code.

    Thanks for the post, had the same issue with the 2550ci, but I changed the complete assembly (DR-895A), just to be sure. The internal clutch/motor test does not help you see the issue, when you activate that motor, it spins nicely, lol. Exactly the same thing, motor turning, but when you trick the machine with the right door open you can see that the Image Transfer Belt is not turning (ITB).

    Re: TaskAlfa 3050ci - J4101 Z-folding jam

    A relative quick and easy check is:

    1) turn off machine
    2) remove rear cover
    3) remove transfer unit
    4) put finger on the claw that drives the transfer
    5) manually turn the motor

    If the claw turns around, it's good. If the shaft is worn, you can prevent the claw from turning by simply pushing gently against it.

    If you really can't be bothered, you could always mark the transfer unit, but that's frowned upon.

    I faintly remember that you can either turn a bushing around or remove a little washer, so the bearing has enough grip on a new bit of the shaft, so you can at least get the customer going while you are waiting on parts.
