According to one embodiment, a scanning system includes a first light source configured to emit a first light beam, a second light source configured to emit a second light beam, a first sensor configured to detect a position of at least one of the first and the second light beams with respect to a photoconductor, a second sensor configured to provide positional information of a transfer system, and a control system coupled with the first sensor and the second sensor and configured to select one of the first light source and the second light source to form a first scan line of a latent image on the photoconductor responsive to output of the first sensor and the second sensor.

Scanning system

An alignment apparatus for use in an electrophotographic imaging device includes a first counter to count a first value of changes of a first signal, with the first value related to a first location of a photoconductor in a first direction. In addition, the alignment apparatus includes a second counter to count a second value of changes of a second signal, with the second value related to a second location of the photoconductor in a second direction substantially perpendicular to the first direction. Additionally, the alignment apparatus includes a circuit coupled to the first and the second counter to generate a change in a third signal after the first and the second counter count to, respectively, the first value and the second value.
