Abstract
An offset electrostatic printer is disclosed which comprises (a) an ion modulated electrostatic print head for forming latent electrostatic images, (b) a dielectric imaging member comprising a layer of dielectric material, (c) means for developing a latent electrostatic image on the dielectric imaging member, (d) means for transferring a developed electrostatic image from the dielectric imaging member to an image receiving surface, (e) 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 (f) means for directing the flow of heated air at, near or through the print head and at or near the dielectric imaging member. The flow of heated air reduces the accumulation of chemical deposits in the print head.
