The fluid assisted ion projection printing head disclosed in U.S. Patent No. 4,463,363 is usable for periodically charging a photoconductor by connecting a simple RC circuit to the modulating jaws of the head. A properly selected AC frequency can also be used to modulate the jaws to allow charges to exit a slit between the jaws periodically with time to bias a receiver moving beJow the jaws. In practice, a .006" wide by 4" long line has been recorded in 1.5 x 10- sec. at 2 psi on a 3 mil thick aluminum red Mylar receiver traveling at 4 inch/sec. A charge to receiver gap of Z .021" was used which provides for an easy mechanical tolerance.
