Image Quality Problems

The image is 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.
■
Make sure the lens is at least 2 inches (5 cm) away from the object you're
viewing.
■
If you're using a projector to display the image, check its focus.
■
Make sure the document camera lens isn't dirty. Use a canister of compressed
air to remove dust. To remove dirt or smears, use lens-cleaning tissue. If
necessary, moisten a soft cloth with lens cleaner and gently wipe the lens.
Caution:
Be careful not to scratch the lens. Never rub the lens with abrasive materials.

For best results, use the 6-foot VGA cable included with the document
camera. If you use a longer cable, the image quality may be reduced, especially
if your computer is set to a higher resolution such as SXGA+ or UXGA. If
necessary, set your computer to a lower resolution, or use a distribution
amplifier to reach a greater distance; you can purchase one from Epson (see
page 28).
