The following fi gure shows an example of paper with holes: the outgoing voltage is constant while passing the paper
between two holes and presents a variation at each hole.
In this case, the optimal value for the “Notch/B.Mark Threshold” parameter is placed about half of the variation.

The following fi gure shows an example of paper with the non-thermal paper printed with black marks and other graph-
ics (for example, a barcode): the outgoing voltage is constant while passing the white paper between two notches,
presents a peak at each black mark and presents some “noise” at each barcode.
In this case, the optimal value for the “Notch Threshold” parameter is located about halfway between the peak value
and the maximum value of the “noise”.
