Toner Fix Analysis Using Numerical Simulation Techniques
Abstract:Numerical simulation method is proposed to predict fix strength on a destruction test of fixed image on a xerography fusing system. The 2-Dimensional ALE (Arbitrary Lagrangian-Eulerian) fluid and non-isothermal simulation can solve toners transitional deforming on a fuser nip and calculate a contact area between the toner and a paper, which takes into account involved factors: viscoelasticity of the toner and its temperature dependence, thermophysical properties of the toner and a fusing material, loading conditions, and fusing temperature etc. In addition, the structural simulation is applied to clarify how a fusing material fit the roughness on the paper structure and is combined with the fluid simulation. The combined method can calculate the contact area on images of both high and low density, which agrees with experiments of that when the type of toner is changed. Additionally, the results show that roughness on a paper structure affects the fix strength which strongly depends on the contact area. This method can be used to design fusing systems and toner properties.

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.
