Also, autocutting ahead of the perforated line may cause problems when feeding paper. Therefore, autocutting must be performed 0.5 mm to 1 mm {0.02 to 0.039"} behind the perforated line.  Therefore, set the black mark position 2 mm {0.08"} or more from the perforation.  For the black mark position of the die-cut label paper, match the label edge to the black mark edge.  The perforations on both sides of the paper shall be uncut. 1 mm { 0.04"} 1 mm { 0.04"} Perforated line Length of the uncut portion Length of the portion 195
