Xerox DocuMate 272 Colour Scanner 90-8017-800 ユーザーズマニュアル

If you’re using the Color Configuration to scan, you can adjust a 
group of color settings. Gamma controls the brightness of the color 
midtones. Saturation is the strength or purity of a color and hue is 
the color your eyes see as reflected from the image.

The following figure shows the color options.

1. Drag the Gamma, Saturation, and Color Hue sliders to the left 

to decrease the settings or to the right to increase the settings.

You can also type a number directly into the setting boxes, or 
click the up and down arrows next to the boxes.

2. Click Reset to return the settings to their original numbers.

You can scan documents up to 8.5" x 14", but you can select other 
scan sizes, or adjust the input size to scan only specific sections of 
an image. For example, if you’re scanning a photograph and want 
to focus on one section, adjusting the input size removes the rest 
of the photograph from the final scanned image.

You can also preview the item and use the Auto Trim option to 
automatically sense the edges of the page, and eliminate the 
sections outside of the edges.
