Solution Steps
During the automatic collimation process, NX normally
applies black borders to the image. These black borders
are intended to mask non relevant areas of the images.
Nevertheless it can occur that the black borders do mask
useful diagnostic information. In this case you must be
able to either hide the black border or re-collimate the
image manually.
Failing auto collimation.
This problem is solved by:
• Hiding the black border.
• Applying manual collimation.
To prevent this problem, use the ROI detection exposure
