Abstract (2. Language): 
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.

Abstract (Original Language): 
Laser yazıcılar sisteminde ince bir tabaka, sandviç şeklindeki iki plastik tabaka arasında bir laser ile ısıtılır. Boya tabakalar arasında erir ve dağılır, yayılma katsayısı sıcaklık fonksiyonuna bağlıdır. Problem t zamanında tabakalar arasında yayılmış boya miktarını hesaplamaktır. Laser ile üretilen eksensel sabit sıcaklık durumu hesaplanır, daha sonra sıcaklığa bağlı yayılma katsayısı kullanılarak yayılma denklemi çözülür ve boya miktarı bulunur. Model, alıcı tabakaya transfer olan boya oranını tahmin etmek ve daha sonra sıcaklık zamanı ile açısal durumu karşılaştırmaktır.
