Solving Problems

■

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.

■

To illuminate your document, press the lamp button on the side of the camera 
head.

■

Use the 

Brightness

 button on the control panel to increase or decrease image 

brightness.

■

Set the 

White Balance

 setting to 

Auto

 to adjust the color automatically (see 

page 17). If the color is still not correct, choose the setting for the type of 
lighting you’re presenting under (

Fluorescent

 or 

Incandescent

).

■

If the image appears stretched while using the document camera’s S-video 
port, press and hold the P

Power

 button for 1 second to turn off the 

document camera. Then press the P

Power

 button again to turn it back on. 

This resets the system and corrects the image.

■

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).
