After you place an object at the needed distance, switch the projector to the Lines and Stripes lighting mode. Adjusting exposure of the cameras (the slider in the Scanning menu), get maximum exposure value, which does not cause red dots to appear on the lines. Areas of the image, not relating to the scanned object, don't matter.
When scanning a high-contrast object it is recommended to enable Second exposure in the Scanning menu. Set the second exposure value higher for dark surface scanning.

The scanner doesn't digitize such areas. Adjustment is performed only by software! Do not touch Iris ring on the lenses, as this will lead to decalibration.
