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 receiver reference and then aligning each printing engines in a cross track direction (z direction) relative to the receiver reference based on measurements in the cross track direction (z direction).
