DC-12 Document Camera

Selected FAQ

Q:
Part of my image is blurred or out of focus. What should I do?
A:
Try the following:

  • 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. See Image Menu.


  • Make sure the lens is at least 4 inches (10 cm) away from the object you’re viewing.


  • If you’re using a projector to display the image, check the projector's focus.


  • Make sure the document camera’s lens isn’t dirty. Use a dry cloth to clean the lens or to remove stubborn stains. You can also use a damp cloth that has been wrung dry.

    Caution: Be careful not to scratch the lens. Never rub the lens with abrasive materials.


  • Make sure the lens is not fogged by condensation. If you’ve just moved the document camera from a cold environment, wait a couple of minutes before using it.
