Abstract
A printer includes print heads configured to eject ink drops onto print media to form images, a controller connected to the print heads to control the print heads to eject ink drops to form the images including one or more test images, one or more actuators to cause the print media to pass the print heads, and at least one camera to capture one or more optical images of the print media after the print media passes the print heads, the controller to detect the test images in the optical images and to measure print characteristics in the test image. A method of measuring ink jet print head alignment includes capturing one or more optical images of media containing printed images, detecting optical images that contain specific printed test images, and measuring print characteristics based upon image data derived from the specific printed test images.
