Title Of Article :
A Model Of The Laser Printing
Abstract :
In a laser printer system a thin layer, sandwiched between two plastic sheets, is heated by a laser. The dye melts and diffuses into the sheets, the diffusion coefficient being a sensitive function of temperature. The problem is to determine the amount of dye which has diffused into the sheets at time t . The axisymmetric unsteady temperature field produced by the laser is determined and then the dye field is found by solving a diffusion equation using a temperature sensitive diffusion coefficient. The model is used to predict the fraction of dye transferred to the receiver sheet at each radial position after a time which is long compared with the heating time.
