67 VISIONEER PHOTOPORT 7700 USB SCANNER INSTALLATION GUIDE
To set the Scan Manager Pro preferences:
1. Click the Preferences button.
The User Preferences dialog box appears.
2. Select the preferences you want:
■Enable selection of color bitdepths...—your PhotoPort 7700
scanner supports a tremendous range of colors, but other devices
(called the TWAIN clients), such as older cameras that you can
use with the Scan Manager Pro support only a 24-bit depth
range of colors. Select this option to automatically allow the Scan
Manager Pro’ s color settings to support more than a 24-bit depth
if the other devices also support the greater range of colors.
■Show standard metric paper sizes—select this option if you use
metric paper to print images. When you select the scan size
output options, the width and height dimensions are then for
metric paper sizes.
■Show standard US paper sizes—select this option to set the
paper sizes for standard US paper.
■Units—select the measurement units for the ruler around the
preview window. The x and y coordinates of the pointer position
are relative to the units.
