How To Change the System Setup
Linx 5900 & 7900
The following trigger types are Level triggers:
• High Level Primary Trigger
• Low Level Primary Trigger
• High Level Secondary Trigger
• Low Level Secondary Trigger
The Edge trigger types generate a single trigger when the sensor signal changes. The Level
trigger types define a continuous trigger condition (active or not active) that depends on the
state of the sensor signal.
To change the trigger option, make sure that the printer is not in the ‘PRINTING’ state.
2.1.2 Trigger to Printhead Distance
Use this option to set the distance between the trigger and the printhead. The default value
is 0 mm. Figure 3 helps you understand the difference between the Trigger to Printhead
Distance and the Print Delay. The large arrow shows the direction of the movement of the
product.
Figure 3. Trigger to Print Head Distance
In this example, there is a fixed distance (C) between the printhead (A) and the sensor (B)
that detects the edge of the product. This distance is the ‘Trigger to Printhead Distance’. If the
printhead and the sensor do not move, the Trigger to Printhead Distance is the same for all
products and all messages. The distance is zero if the printhead and the sensor are in the
same position. The installation engineer enters this measurement into the printer during the
installation, but you can change the value if the sensor position is changed.
In Figure 3, the trigger signal from the sensor occurs at the edge of the product, but the
message area (E) is not at the edge of the product. The distance between the sensor position
and the print position (E) is the Print Delay (D). This distance depends on the product. The
Print Delay parameter is described in the Linx 5900 & 7900 Quick Start Guide.
