One of the persistent problems in the development of laser printer is paper wrinkles in fusing process. Factors affecting this problem are due to internal factors of fuser and layout factors between transfer roller and fuser. This paper suggests modeling methods to simulate mechanical characteristics to predict the possibility of paper wrinkle in fuser by change of layout parameter. Layout parameters are relative position and angle of fuser about transfer roller and inlet guide position from fuser nip. Through 3D dynamic simulation, it calculates the compressive plastic strain of the paper passing through the fuser unit, and wrinkle criteria were set up on the basis of jig experiments. The analysis method can be extended to a variety of practical paper wrinkle problems, and the scalability is considered high. The usefulness of these methods was validated by the comparison with experimental results.
