Patent ID: 8503037

Claim:
A method for reducing non-separable error in image on paper (IOP) registration in the image path of a multifunction device, the method comprising: receiving a pre-defined number of digital images into an image path of a multifunction device; receiving an estimated amount of separable error that can be compensated for by an electronic registration process; for a first side of each digital image: for each of a process and lateral direction for said first side: determined an amount of total IOP registration error in each respective direction; and subtracting said received estimated amount of separable error from said determined amount of total IOP registration error to obtain an amount of non-separable error for each respective direction; calculating over said number of digital images, an average amount of non-separable error for each of said process and lateral directions; and adjusting said multifunction device to compensate for said average amount of non-separable error, said adjusting comprising: retrieving at least one device-specific setting based upon a magnitude and a direction of said average amount of non-separable error; and applying said device-specific setting to said multifunction device such that said device is adjusted to compensate for each respective average error value in each of a process and lateral direction.
