Method of apparatus for measuring image alignment errors for image formation in image forming apparatus |
摘要 |
A method of and an apparatus for measuring image alignment errors for image formation includes printing two test marks separated from each other by a designated error distance on a printing medium on which images are printed, sensing the two test marks, measuring instants of time when the two test marks are sensed, and detecting an actual error distance of the two test marks using the measured instants of time and a moving speed of a carriage.
