Measuring Cleaning Performance in an Electrophotographic Process
Abstract:A technique to measure cleaning performance, using particle counting, in an electrophotographic process is reviewed. Steps to transform a post cleaning area tape sample into a visual, image while minimizing external noise factors, are outlined. Once presented to the image analyzer, examples of samples manipulated to enhance the residual toner particles using a high gauss filter are illustrated. The number of particle counts needed for each sample to provide some type of statistical significance is discussed. This is followed by an explanation of how these components were integrated into a short computer program to further minimize amount of time the measurement involves. The final element of this technique, correlating the collected data to cleaning performance, is examined considering both its benefits and limitations as a measurement tool.

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.
