Installation
4. Select the option you want.
• Full Install (OneTouch and TWAIN)—This is the 
recommended installation. It installs the One Touch 4.0 
software which provides the necessary driver software for 
the scanner. It also installs the scanning interface for the 
TWAIN driver. Installing this option means that you can use 
several different methods to scan, as explained in this User 
Guide. 
• TWAIN Only—The TWAIN driver is installed. The One 
Touch 4.0 Monitor will not run and you cannot use the One 
Touch features. You can use the TWAIN driver to scan from 
applications with a TWAIN interface. You also will not be 
able to scan with the buttons on the scanner.
5. Click Next.
During installation you will see this window asking you to select 
one of the images for the Color Space setting.
The Color Space setting sets the gamma value for the scanner 
so scanned items look good on your monitor. Gamma controls 
the brightness of the midtones of colors. That setting can be 
changed later on as you’re scanning.
NOTE: If your computer is running Windows XP or Windows 
Vista, Microsoft’s Windows Image Acquisition (WIA) interface for 
scanning is always available, regardless of your selection on this 
window.
NOTE: If you decide to change the scanner’s installed drivers 
later on, you must first uninstall the drivers the scanner is 
currently using. See the section “To Install Another Driver” on 
page 113.
