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.
