%X Laser printer internal parts are prone to deformation when they are working in high temperature environment for a long time, resulting in machine faults such as paper jam and angle folding. In order to predict the deformation of parts in thermal environment and further determine their initial allowable deformation, so as to guide the structural design and production process of parts, and to reasonably determine the stress mode of parts in the working process, the structural deformation of the complex injection part-fuser upper cover in a laser printer after long-term operation in thermal environment is studied. First, on the basis of fusing temperature control technology and heat exchange analysis of the whole machine, the internal temperature field of a laser printer is numerically simulated by using the flow and heat transfer analysis software, and the temperature data of the key parts inside the machine are obtained more accurately. Then, the sequential coupling method is used to apply the results of thermal analysis of the whole machine as the external loads of static stress analysis to the fuser upper cover model, and the structural thermal deformation data of the fuser upper cover are obtained
