Depth Camera failure

When trying to scan, the depth camera only shows half of the image. The left half is black and it only shows the part on the right side. When I hold a sheet of white paper in front of it the left half is black and the right side I can see it. Adjusting the slider does nothing. Please help!

Please post a screen shot of the software, I need to see also the blue preview , include info about what scanner you are using and what platform and what version of the software .

you need to hold the paper with Mini at around 10-20 cm, POP2 about 15-25 cm
same with scanned objects , they cant go too close as the FOV will cut it in half
do the paper test and post it .
