Aligning Preprint And Thermal Print
The printer can synchronize the cutting of the printout with black-marks printed on the back of
the paper. Use this function when you have preprint on the media and you don't want a cut in
the middle of that preprint, or text printed on top of the preprint.
The sensor used to detect the black-marks is the same sensor as used for paper end detection. It
is positioned 9 mm from the edge of the paper on the side of the
blue release arm, and 25 mm
behind the cutter (as seen from the presenter [output] side of the printer). The sensor accuracy
is about ±0.5 mm so avoid designing printouts with too high demands for synchronization.
Figure 22 • Recommended black mark size and position
The sensor triggers on the black-to-white transition of the black-mark, which is when the black
print ends (trailing edge).
