Banding is an image artifact that appears as peroidic light and dark bands across a page. This paper presents an experimental study on the application of a piezoelectric laser beam deflection device to reduce banding in the electrophotographic process. Banding is characterized using several different measurement techniques. An empirical model of the actuator is obtained using system identification techniques by measuring the laser beam position on-line using an optical sensor. An open loop control strategy is then proposed and implemented. Experimental results showed significant improvements with the images printed using beam deflection control.

  • 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.
