Intermediate transfer belts represent an important technology component of the two-transfer systems commonly found in color laser printers. A number of mechanical and electrical properties contribute to the performance of intermediate transfer belts in these systems. Of these, resistivity and dielectric permittivity are two of the most critical electrical properties and are related to the bulk properties resistance and capacitance, respectively. Accurate measurement and specification of these electrical properties is important to the design of two-transfer systems.

Recently, an electrical characterization method for intermediate transfer belts was published [1], where the resistance and capacitance were determined from amplitude and phase measurements of an applied A.C. voltage. We report on implementation of and improvements to the previously published method. It was found that the previous implementation did not make efficient use of all measured data. We derive a more efficient and robust estimator for the resistance and capacitance of a transfer belt based on measurements of gain and phase. We also performed a gauge repeatability and reliability study of the fixture. Our approach represents a significant refinement of the previously published characterization approach for intermediate transfer belts.

  • 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.
