Abstract

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.
