Simulation Model to Predict Paper Wrinkle by Transportation Force Analysis
Abstract:A simulation technology to predict a paper wrinkle in electorophotography printing process is developed. The paper wrinkle is a phenomenon that minute crease occurs on paper, and it is one of the major chronic troubles in electrophotography. To prevent the occurrence of the paper wrinkle, optimization of fusing parameters is necessary but enormous costs and hours are required for experimental approach. 3-dimetional dynamic structural simulations have been generally applied to predict the paper wrinkle, but they have not reached sufficiently practical level in terms of prediction accuracy, calculation stability and computational load. We established a simulation model based on a 2-dimentional static structural simulation in the plane perpendicular to axial direction. By using transportation force distribution exerted on paper in fusing nip as an evaluation index, prediction of the paper wrinkle occurrence rate became possible. The developed simulation technology was utilized for design of the radius difference rate of a fusing roller, and the optimum parameter was determined.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
