• If the surroundings are dark and the contrast in the projected image
is low, the document camera's auto focus function may not work
correctly. Adjust Brightness and/or Contrast in the Image menu.
• Make sure the camera head is at least 5 cm (2 inches) away from
the object you are viewing.

Cannot focus on a three dimensional subject
If the subject is a three-dimensional object, the following will make it
easier to bring it into focus.
• Place a uniformly colored 11×17 or A3-size or larger object as a
background for the three-dimensional subject.
• Before placing the three-dimensional subject, focus on the position
where the subject will be placed.
Other image problems
• If the image is stretched or has black bars, change Output Resolution
