I have a Riso RN2030UI that gives me an A34-218, the service manual doesn't really help much on the issue. When making the master for a print job the duplicator jams the first master when it is headed to the master disposal, once the jammed master is removed I unroll the master roll back far enough that there is no slack but the master roll is not past the master stopper, if placed behind the master stopper the paper jams. If you do put the leading edge past the master stopper the roll works fine on the second attempt to make the master.
