I found that the plastic guide plate bows slightly upwards (red arrow direction). You can see a fair amount of bowing/springyness when pushing down with your finger at that point. This results in the metal strip at the base of that separation rubber to be a higher level than plate A, and the paper catching the metal strip sometimes, resulting in exactly the situation in the OP's photo. To test this I placed a couple of paper wedges at the points of the green arrows to push the guide plate downwards, and no jams there whatsoever. The only thing is at the point (black arrow) where the guide plate then contacts the separation roller and torque limiter (especially that little plug at the side of the limiter), I had to file down a bit to maintain a gap, beware of that, but it seemed to work. Is it a different type of plastic on those guide plates/DF's that warps easier, should there be another screw to hold it down at that point, is that a part that needs replacing ?, I don't know, but that explains the fold on the paper at the point and subsequent jams. I hope this helps.

Good tip..........had the same issue a couple of days ago with the sep roller indentations on the jammed original, which we resolved replacing the feed belt and sep roller as a set. If the customer calls back with that same jamming issue--and those distinct sep roller indentations-------I'll bet the plastic guide plate warp will be the issue.
