I forgot to post this.
I was able to fix my J-61 Duplex jam problem when feeding from a LCC Only.
What I did, was to take the springs that put pressure on the Nylon rollers that contact the gray rubber rollers on the Duplex section. I stretched the springs about 2mm, and that took care of the problem. Been running fine for about six months.
Sorry about the delay.
