In an electrophotographic copier machine, fuser rolls are typically brought together to exert pressure on paper passing between the rolls in order to aid in fusing toner to the paper. As a consequence of the forces needed, heavy AC motor drives and complicated transmission systems including clutches have been employed. This article describes a roll closure mechanism driven by a small DC motor yet capable of exerting the required roll closure forces. In so doing, reliability is improved, and the need for adjustments minimized.
