6 ALIGNMENT
The device is provided with a sensor for the use of alignment black mark in order to handle rolls of tickets with pre-printed
ields and a ixed length.
The alignment sensor is a “relection” sensor: this kind of sensor emits a band of light and detects the quantity of light
relected to it. The presence of the black mark is therefore detected by the amount of light that returns to the sensor, con
-
sidering that the light is relected by the white paper and absorbed by the black mark.
To ensure the correct alignment, you must enable the “Black Mark Position” parameter during the setup procedure (see
paragraph 5.6 ).
The following paragraphs show how to correctly set the coniguration parameters of device in order to assure the alignment.
