This article describes the use of jump phenomena to minimize power input and reduce the cooling requirement for a low speed, low cost printer. A phenomenon appearing in a nonlinear vibration system governed by Duffing's equation which is expressed: X Omega(o)/2/ X + h X/3/=G Cos Omega(f)t (1) is a discontinuous jump in output amplitude, X, as either the frequency, 1(f) or the magnitude, G, or both of the driving functions are varied smoothly and continuously. (In Duffing's equation (1), X is the displacement output, Omega(o) is the natural frequency of the system, h is the nonlinear stiffness parameter, G and Omega(f) are the amplitude and frequency of the forcing function, respectively. ) This jump phenomenon can be used in an impact printing system.
