• Known writing devices for outputting stored data in a tachograph generally have a spiked roller, the spikes of which penetrate into edge perforations of the paper strip and ensure the advancement of the paper strip under the printing unit.

• the printing unit is adjusted relative to the area to be printed on a reference position. The Adjustment is to ensure that the data, for example a graphic representation of the driving speed of the motor vehicle, is transmitted over time in the intended positions on the grid.
• a disadvantage of the known tachograph and the known paper roll that tolerances between the printing unit and the visible grid of the area to be printed of the paper roll can occur, so that the position of the data is not reliably guaranteed to the visible grid.
• Such tolerances can lie in the components of the tachograph itself, for example, by an inclination of the spiked roller or in the position of the printing unit.
• tolerances may arise due to geometry fluctuations of the paper dimensions or of the optically visible grid.
• tolerances can also be caused by moisture absorption of the paper strip during operation of the tachograph.
• the invention is based on the problem to design a tachograph of the type mentioned above so that a reliable orientation ⁇ to the printing unit in relation to the zero line of the area to be printed is guaranteed. Furthermore, a paper strip for such a tachograph is to be created, which ensures reliable alignment with the zero line of the area to be printed in the tachograph. Furthermore, a method for aligning the paper strip to the printing unit of the Fahrschrei ⁇ bers to be created, which allows a reliable assignment of the printed data of the tachograph against the zero line of the paper strip.

• the control device is able to align the printing unit on the basis of the signal sequence of the sensor. Since the signal sequence of the sensor depends on the detected markings and the detected markings differ widely lie across the zero line and thus to the direction of movement of the paper strip, depending on the position of the paper strip relative to the sensor different numbers of marks are scanned. This leads to a signal sequence corresponding to the position of the paper strip relative to the printing unit.

• a swelling of the paper strip can be according to an advantageous embodiment of Consider the invention in the output of the data simply when a sensor for scanning marks of the paper strip is arranged on both longitudinal sides of the paper strip and when the control device is designed to determine a width extension of the paper strip in response to the signal sequences of the sensors.
• the control device can prepare a graphic to be printed in such a way that, when the paper strip is widened, the graphic to be printed is stretched or compressed as the paper width becomes smaller.

• the markings are particularly simple in construction according to an advantageous embodiment of the invention, when the Markie ⁇ tions periodically arranged to each other and have different lengths.
• a disturbance of the transmitted data by the markings can be easily avoided according to an advantageous development of the invention, when the markings are arranged on the back of the area to be printed.
• a source of the paper strip for example by teeinflüsse Feuch ⁇ easily can be detected by means of two sensors disposed in the tachograph when the marks on two longitudinal sides of the paper strip are arranged.
• the third problem namely the creation of a method for aligning the paper strip with respect to the printing unit of the tachograph, which enables a reliable Zu ⁇ order of the printed data of the tachograph against the zero line of the paper strip is inventively solved in that a series of transverse to Be ⁇ direction of movement arranged on the paper strip and different lengths markers is scanned by a sensor that detects a control device from the signal sequence of the sensor offset of the printing unit to the zero line and controls the printing unit to adjust the offset.
• This design of the Sen ⁇ sors is determined the position of the paper strip and driven, the printing unit based on the signal sequence and aligned over the NuIl- line based on the signal sequence. In this way, tolerances are compensated between the printing unit and the zero line and thus to ⁇ reliable assignment of the printed data of the originallyschrei- secured against the zero line.

Therefore, a protagonist- of the printing unit ADORABLE curve of the expression can be constantly maintained at the vorgese ⁇ Henen orientation to the zero line preferably.
• Manufacturing tolerances of the printing unit can be easily compensated according to another advantageous embodiment of the invention, when a line is printed at a first adjustment of the printing unit of the tachograph against the zero line of the paper strip when an offset of the line is measured to the zero line and entered into the control device and if the control device compensates for the measured offset in the control of the printing unit.
