Abstract
A method of forming an image on recording media includes providing a rotatable imaging drum adapted for supporting the recording media; providing an imaging head adapted for forming the image on the supported recording media; providing an encoder adapted for detecting incremental rotational positions of the imaging drum; positioning the imaging drum at a non-incremental rotational position; detecting one or more points on an edge of the supported recording media while the imaging drum is positioned at the non-incremental rotational position; determining a position of each of the detected one or more points; and operating the imaging head to form the image on the supported recording media in alignment with at least the determined position of each of the detected one or more points.
