Abstract

This invention relates to a system for non-impact printers such as those that use light emitting diodes (LEDs) to produce an image on a photoconductor. In such devices, a discontinuity is generally created in a line of printed characters because of the movement of the imaging surface relative to the LED array. The system of this invention eliminates such discontinuity through adjustment in the enabling sequence of the LEDs of the array.
