Abstract
A justification system is provided for use in an electrophotographic printer. The justification system comprises a detector which detects the passage of individual segments of a continuous form which are being fed at a predetermined rate. A counter counts the number of main scannings of a laser beam carrying printing information over the surface of a photoconductive drum. A read control is connected to the detector and the counter and controls reading of main information stored by monitoring outputs from the detector and the counter so that printing of each segment always occurs at a predetermined position, synchronously with passage of the segments.
