If the maximum value of “noise” read by the sensor is very close to the peak value, it might be dif fi cult to place the
value of the “Notch/B.Mark Threshold” at an intermediate point. In these cases, it is mandatory that the portion of
paper between the point of printing end and the front notch is completely white (no graphics). In this way, the only
next graphic detected by the sensor for alignment after the printing end will be the notch.
10.3 Alignment parameters
The “alignment point” is de fi ned as the position inside the ticket to use for the notch alignment. If you use paper with
perforation (FanFold modules), the alignment point corresponds with the edge of the ticket.
The distance between the notch edge and the alignment point is de
fi ned as “Notch Distance”. Referring to the front
of the notch, the value of “Notch Distance” can be positive or negative. If the “Notch Distance” value is set to 0, the
alignment point is set at the beginning of the notch.
