Abstract
Paper curl is one of the major troubles in electrophotography, and decurler device is put into place in order to reform paper curl. At decurler device, paper is bent in large curvature against curl direction to be reformed. In doing so, reformation amount of paper curl is affected by radius of roller, nip load and other decurler parameters. In addition, curl amount to be reformed varies with paper brand, fusing system and image density. For these reasons, enormous costs and hours are required for designing decurler parameters. To resolve this problem, we built a simulation model to predict paper curl reformation by numerical model considering paper characteristics such as elasticity, plasticity and viscosity. As a result, we established simulation technology to design decurler parameter on virtual experiment.
