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).
Claims20
A method to align an electrophotographic printing engines in a print assembly that is capable of printing on a receiver to form one or more final prints including corrections for cross-track misregistration comprising:
- aligning two or more printing engines in an x and y direction;
- and
- aligning a first printing engine to a second printing engine in a cross track direction (z direction) based on a cross track (z direction) position of the receiver as measured by the second engine.
An apparatus for digitally printing comprising:
- a plurality of electrophotographic printing engines in a print assembly that is capable of printing on a receiver to form one or more final prints wherein the print engines are allignable in an x, y and z direction relative to a receiver path cross track reference wherein the receiver path cross track reference is based on measurements in the cross track direction (z direction) relative to the receiver path cross track reference;
- a measurement device to measure the distance between each of the at least two receiver related references;
- and
- an alignment device to align the two or more printing engines in the cross track direction (z direction) relative to the receiver path cross track reference.
