In order to get constant imprint precision, the print mark must be directed
as evenly as possible past the print mark sensor. Therefore, set the print
mark sensor directly over a guide plate.
If the print mark is cut off by the edge cut or the print mark is on the back
side of the printing, you have to set the print mark sensor on the round
bar of the longitudinal cut cassette and adjust it there to the print mark.
Use a counterholder if you set the print mark sensor on the round bar of
the longitudinal cut cassette.
Heed the changed sensor distance to the cutting cylinder unit.
