When the leading edge of the carton contacts the print drum, the drum begins to rotate in a clockwise direction as
shown in Figure 35. The die travels a short distance and then contacts the ink roll where ink is applied to the die
face. When the die contacts the carton the mark is applied. The print drum will continue to rotate until the trailing
edge of the carton passes the coder. As soon as the Print Drum disengages from the carton, the spring return
mechanism will automatically return the Print Drum to the same relative starting position.
To adjust the position or registration of the code imprint on the side of the carton, loosen the Print Drum Knob and
rotate the Print Drum to move the leading edge of the printing die in the appropriate direction and re-tighten the
Print Drum Knob. Moving the leading edge of the printing die rotationally away from the leading edge of the carton
will result in the code being printed more towards the trailing edge of the carton.
