Abstract
The current disclosure discloses methods of and systems for automatically adjusting or selecting a pitch between beams in a multi-beam scanning system. An array of light sources is mounted on a rotatable housing and emits light in a direction perpendicular to the rotational plane. The system or method measures a pitch on or near an intermediate image-forming surface. In response to the measured pitch, the scanning as well as sub-scanning pitch is automatically adjusted or selected by rotating a housing unit to maintain a desired pitch.
