Abstract
The AC discharge method of ionographic printing developed at Dennison during the late seventies employs a large array of individual printing sites. Obtaining uniformity among these sites has long been recognized as a requirement for high quality printing. Recently, attention has been directed toward improving the uniformity of the output from any one site. This paper describes an experiment to measure the charge produced by an individual ion generation site. The apparatus constructed directly records the charge produced by 4096 consecutive AC burst firings of one site at a rate of 12 KHz. This is comparable to printing one page at 300 dpi. and 200 feet per minute. These measurements are analyzed to show the average charge output, and the distribution of the charge amplitude. Results are presented which show the effects of variations in the applied voltages around the normal printing conditions. Additional experiments give insight into the processes involved in printing from an AC discharge. The use of nitrogen as a working atmosphere for a print cartridge is explored.
