Patent ID: 7996181

Claim:
A method for sensor phasing, comprising: implementing a comparison algorithm via a computer-implemented system comprising a processor, a data bus coupled to said processor, and a computer-usable medium embodying computer code, said computer-usable medium being coupled to said data bus, said computer program code comprising instructions executable by said processor, with respect to a photoreceptor substrate edge signal in at least one complete revolution of a photoreceptor substrate and said photoreceptor substrate edge signal sensed in a region of interest of said photoreceptor substrate, wherein said comparison algorithm returns a best comparison when said photoreceptor substrate edge signal in said at least one complete revolution of said photoreceptor substrate and said photoreceptor substrate edge signal sensed in said region are registered in-phase with one another; utilizing information output from said comparison algorithm to phase align a process sensor with respect to a bare photoreceptor substrate and said region of interest via said computer-implemented system; and applying a normalization algorithm to said process sensor signal using a bare photoreceptor substrate signal to remove artifacts and compensate for non-uniformities via said computer-implemented system, thereby increasing a fidelity of a resulting marked photoreceptor substrate signal from said process sensor.
