    Abstract: A cooperative plurality of energy-dissipating means is incorporated into a high-speed mechanism so as to be sequentially activated and be operative upon a working member for timely extraction of precise quantities of excess kinetic energy and for producing long life and bounce-free fast operation of the working member. Incorporation of the invention into a high-speed printer wherein energy absorption from components of the printer is accomplished via structurally improved members is also disclosed.
