To design faster and safer printers with scorotron, it should be highly effective in charging of rotating optical photoconductor (OPC). In high speed printings, the time scale of rotation and charging competes and the charging processes goes to transitional. So, we have to understand dynamics of charging processes for effective charging scorotron. But, the dynamics of charging of rotating OPC by scorotron is not well understood. The authors have recently developed a numerical model of the dynamics of charging rotating OPC and ionic wind by positive DC scorotron. The calculation by the model well reproduced the measured electrostatic potential on rotating OPC and velocity of ionic wind in steady state. The authors show how electrostatic potential on rotating OPC and charge density distribution change with time. The authors also show that the charging time scale by the model.

  • 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.
