A xerographic print engine employs a photoreceptor with an image receiving surface, a printhead for directing light to the photoreceptor to produce thereon a latent image, and a developer for converting the latent image to a printable image to be transferred from the photoreceptor to a print medium during a relative motion between the photoreceptor and the print medium. The printhead has light emitting diodes (84) disposed in plural rows (82,86) arranged alongside each other on a substrate which also supports driver circuitry connecting with imaging electronics for activating individual ones of the diodes. An optical element (lens 30) focuses light of the diodes onto a row of the latent image, the focussing being accomplished concurrently for individual ones of the diodes located in a plurality of the rows.
