Abstract
The adjustment method aligns printing engines in a print assembly that is capable of printing on a receiver to form one or more final prints and includes corrections for cross-track misregistration. These adjustments are made in one embodiment by aligning two or more printing engines in an x and y direction relative to a paper path cross track reference and then aligning each printing engines in a cross track direction (z direction) relative to the paper path cross track reference based on measurements in the cross track direction (z direction) relative to the paper path cross track reference.
