The angular velocity fluctuation of the Organic Photo Conductive (OPC) drums causes the halftone banding that is a main source of the print quality degradation represented as the irregularity of the line spacing. In addition, the mechanical connections between various components in a gear train involve the fluctuation as a source of the vibration. This paper suggests modeling methods to simulate dynamic characteristics to predict the fluctuation of gears and other components affecting the banding. The model-automation tool building easily and quickly a simulation model is developed by using Finite Element Analysis (FEA) software. The usefulness of these methods is validated by the comparison with experimental results.
