Image Quality Problems
The image is fuzzy or out of focus
•
The document camera needs hard edges or sharp lines in the image to
be able to focus properly. If the image has only soft edges, try placing a
different document under the camera lens while adjusting the focus. Or
focus the image manually with the
Focus adjustment in the Image
menu.
