ABSTRACT:
An electrostatic print head system is disclosed which comprises an ion modulated electrostatic print head, means for supplying a flow of heated air having a temperature in the range of from about 120.degree. F. (49.degree. C.) to about 200.degree. F. (93.degree. C.), and means for directing the heated air at, near or through the print head to reduce chemical deposit accumulation at the print head. The print head may comprise a modulated aperture board having a plurality of selectively controlled apertures therein and an ion generator for providing ions for electrostatic projection through the apertures. The electrostatic print head system may be used for forming latent electrostatic images and employed in an electrostatic printer which further comprises a means for developing the latent electrostatic images.
