Example:
In this example the print shall be carried out on tubes. The printout is an endless print
(e.g. Type, date of manufacturing, material etc.) and not each tube has the same length.
In addition the distances between the tubes are not always the same. The basic
mounting of the sensor and the print head is shown in Picture 11.

As shown in Picture 11 the print head and the sensor should be installed in parallel to
each other. If the sensor and the print head would be installed in row the stopping of the
printout at the end of a tube would be either too early or too late.
The printout shall start with the beginning of each tube and it shall stop at the end of it
without printing in the space between the tubes. For this a sensor which recognizes the
beginning and the end of a tube is used. The output of the sensor is connected to the
PrintGo and the PrintGoGate input of the Printer printer (see Picture 10). With this
design the PrintGo signal together with the PrintGoGate signal starts the printout and
with the negative edge received from the sensor at the end of the tube the printout
stops.
The signal from the sensor is used for the PrintGo input as well as for the PrintGoGate
input. For the PrintGoGate input you need a high level and not only a positive edge as
for the PrintGo input. Therefore it is important that the signal from the Sensor is a
signal level and not only a signal edge.
