If the paper if getting a fan fold and then jamming at the fuser unit, this would suggest a pick off finger may have come off its mount or spring. If the paper clears the fuser ok put has an elephant skin type wrinkle down it, then this would suggest fuser is past it's best and should be replaced. Remove the fuser and check there is nothing wrapped round one of the rollers. If all is clear, change the fuser.
