Dynamic Electrical Conductance Profiles of Liquid Electrophotographic Inks and Corona Devices
Abstract:Spatial, cross-sectional, electrical conductance profiles of the ink (toner) “nip” and charging corona “nips” are measured as a function of position and electric field for purposes of programming into a dynamic analog electronic circuit model of an emerging, high quality liquid electrophotographic process. The circuit model itself, and its performance, are presented in a separate paper. The space charge states for various experimental liquid inks will be discussed, along with the particular transport parameters. Detailed calculated transient current flow, photoreceptor surface voltage rise, and resulting image deposition for a tiny unit area of photoreceptor traversing the development nip (within the development nip itself), will be discussed for various experimental process situations.
Experimental, field dependent, spatial conductance profiles for the involved corona charging devices will include scorotrons and corotrons, specially designed for the process.

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.
