My babylock Ellisimo Camera is darker and image is not being recognized

The camera on the Baby Lock Ellisimo BLSO automatically changes the brightness to level “5” while searching for the embroidery positioning sticker. If the camera is not recognizing images, it may be because the embroidery positioning sticker is not correctly placed or the pattern is outside the embroidery field. In this case, reposition the sticker so the pattern is within the embroidery field and press again.
