A lateral position of a photoreceptor belt is detected by at least a first sensor and a second sensor, respectively located near a first imager and a second imager. The detected lateral positions of the photoreceptor belt by the first sensor is compared to the detected lateral position of the photoreceptor belt by the second sensor. Based on this compared difference, a correction is applied to the position of the second imager relative to the photoreceptor belt. To apply the correction, the location of the start of scan (SOS) of the respective imagers is moved.
