Abstract

Techniques are disclosed that enable fine features such as serifs and narrow strokes of texts to be produced by xerographic devices, for example. The fine features may be generated by subpixels which are produced when a pulse width used to image a pixel is shorter than a corresponding physical size of a laser beam spot used to write the image on a Xerographic photoreceptor. The laser driver may be modified to drive a light emitting element with a boost current profile that includes an overshoot above a steady state current at a rising edge. The overshoot results in a light intensity time profile that has an increased area for a subpixel.
