Where'd you pull that from? The only time I ever saw an accordian type jam was when someone reinstalled the dryer on our 340 somewhat off kilter and the paper jammed at the dryer entrance.
It was in between the paper magazine climbing up the previously mentioned "elevator" thingy and leading towards the laser exposure unit. I'm still not sure how it ended up being that long, or how there was space for it as the mechanics of the machine are obviously designed to keep the paper flat. We hung on to it for several weeks just because it was such a neat thing to look at!
Gotta love them!
