Set the SW-1 position of the DIP switch to ON and correctly set the GS (F) command to select the black mark positioning print.

(2) Black mark detection locations:

The black mark is located on the right side of the front of the document. The relationship between the black mark detection switch position, the printing start position, and the tear line position of the printer head is shown in the diagram below. The printer detects the black mark approximately 2 mm from the center of the black mark detection switch where the leading edge of the black mark has passed.
