TEST PATTERN LESS PERCEPTIBLE TO HUMAN OBSERVATION AND METHOD OF ANALYSIS OF IMAGE DATA CORRESPONDING TO THE TEST PATTERN IN AN INKJET PRINTER

摘要

A method generates a test pattern on an image receiving member that is less perceptible to human observation, but still detectable by an imaging device within a printer. A method implemented in the printer analyzes image data of the dashes in the test pattern that were randomly distributed in the process direction within an area of the image receiving member to identify positions for printheads in the printer and detect missing inkjets in the printheads.
