Numerical Simulation of the Toner Melting Behavior in Fuser Nip Considering Toner Rheology
Abstract:New numerical method to compute toner melting behavior in the fuser nip was developed by combining the recently proposed CCUP method known as a general solver for gas, liquid and solid and the Leonov model as a rheological model. In present method, deformation of the piled up powder toners by heat and load were computed using the fitted dynamic property of the viscoelastic parameters: G', G” and the WLF equation. In this study, effects of the fusing temperature, the nip load and the process speed on melting behavior were investigated. Consequently, the computed toner pile height and the surface roughness show good correspondence with experimental ones, and the validity of the present method was demonstrated.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
