ABSTRACT:
An apparatus, system and method of print registration are provided. The invention includes first and second optical channel modules configured to communicate light from a page to a sensor module. The sensor module sums the light from the first and second optical channel modules and detects one or more light transitions as a first registration mark of a first image of the page moves past the first optical sensor module and as a second registration mark of a second image of the page moves past the second optical channel module. The invention determines that the first image and the second image are registered if the sensor module detects a single light transition as the first registration mark and the second registration mark pass the first and the second optical channel modules. In addition, the invention determines that the first image and the second image are mis-registered if the sensor module detects a plurality of light transitions as the first registration mark and the second registration mark pass the first and the second optical channel modules.
