3.4 Issues Related to Image Acquiring
3.4.1 FailedStream Acquiring
The port is not a GigE port and Jumbo is disabled. Trigger is disabled for the camera.
Figure 3-1Network connection
3.5 Issues Related to Debugging and Installation
1. Only a line is captured by the camera: It is possible that the sensor and the scan
line are not in parallel.
2. Focus issue: Use an object (without burrs) with a clear border between the bright
side and dark side to make the camera focus on the border.
Figure 3-22 Focus issue

18
3. Images of the same type of products have huge differences: The light source is
not in parallel with the captured object. We recommend you install the line scan
camera horizontally. If the camera is installed slantly, you can install a fixed part
to unify the installation angle.

4Cleaning and Maintenance
This chapter mainly introduces cleaning and replacement of color filter.
We have installed a fully transparent protective glass for the mono camera with the
main purpose of preventing dust from falling on the surface of the image sensor. The
color camera is equipped with a low-pass filter that cuts off to the near-infrared band.
If you have special requirements, such as not using a color filter or using another
light-transmitting filter, you can replace the entire filter mount of the image sensor (no
need of removing the cover).
If the surface of the filter needs to be cleaned, we recommend using the special
cleaning agent for optical devices that can clean the surface without leaving a mark.
