摘要：
A detector assembly for detecting registration marks on a printed sheet when different color printing on different colored sheets is present has a pair of light sources and a light sensor. The light sources are of different colors selected to be complimentary such that one light source or the other will be capable of detecting a substantial range of contrasting registration marks placed on sheets that can be of various colors. Controls are used for selecting the light source that provides an output sensed by a light sensor when passing over the registration marks.
