Abstract
This paper describes the application of finite element analysis to calculate the dynamic response of a xerographic laser printer write head known as a "raster output scanner" (ROS). Steady and transient dynamic loading conditions are applied to a structural model of the ROS component support casting which has mathematical relationships accounting for the opto-mechanical interaction of 14 laser spot conditioning lenses and mirrors with the mounting structure. The output of the these relationships describe the dynamic response of the laser spot at the photoconductor surface. The response amplitude is then compared to a motion specification to determine if perceptible defects in xerographic prints will occur.
