Abstract
A method for detecting, in-situ, a cross-process linearity error in an image printing system that prints on an image bearing surface movable in the process direction is provided. The method includes placing marking material to form of a row of registration marks on the image bearing surface, detecting a position in a cross-process direction of each registration mark in the row using a linear array sensor that extends in the cross-process direction, and determining a correction function with a processor using the positions of the registration marks as detected by the linear array sensor to compensate for an error in the positions in the cross-process direction of the registration marks. The row of registration marks extends in a cross-process direction transverse to the process direction.
