Abstract:
A three-dimensional object printer is configured to generate a printed predetermined test pattern on a substrate in the printer with a plurality of ejectors in a printhead. An image sensor generates image data of the printed test pattern and a controller identifies a z-axis distance between the printhead and the substrate using a dispersion identified between cross-process direction distances separating printed marks in the test pattern.
