Paper Abstract

The ion-jet printing method controls the ion flow directly to make an electrostatic latent image on an insulated layer. This printing method has several advantages over laser printing, such as high printing speed and simple maintenance. However, conventional ion-jet method poses a problem, particularly for office printer applications, because a high- voltage circuit is required to control the ion flow. We developed the new ion-jet printing method to solve this problem. The new process uses a precharge to accelerate the ion flow to the insulated layer, and the high-voltage bias is eliminated from the head. So, the new ion-jet head permits controlling the ion flow by a low-voltage signal. Experimentally, we attained a printing speed of 20 ppm and a resolution of 400 dpi at the control voltage of -30 V, and succeeded in printing Chinese characters with 32 X 32 dots per 2 mm square.
