We propose the Double-Resolution LED Printer which introduced the liquid crystal light shifter formed of a birefrigent crystal and a liquid crystal element into the LED arrays print head. This method can double the printing resolution for the density of the LED elements assembled on the head. Printing data of a line are divided between odd data and even data. All LEDs alternately illuminate for the odd and even data. In exposure for even data, the liquid crystal light shifter shifts the irradiated position on the photoconductive drum to half distance between each LED elements. Therefore, the printing resolution can double for the density of the LED elements. In this paper, we show the theory of this system and the basic experimental results of light beam shift, and we show the possibility of double-resolution printing.
