Abstract
We have modeled the charging process of rotating organic photoconductor (OPC), ionic wind and ozone transport by positive direct current (DC) scorotrons. The models have been validated by comparing numerical simulation and experiment. We have shown that the potential on OPC after charging decreases in higher printing speed, though the drum current increases. With numerical simulation of the charging of OPC and the ionic wind, we have conjectured that the charging of OPC will be less effective, concentration of ozone will be higher and the contamination of the wire will be severer when we increase the corona current.
