No portion of this document may be reproduced Introduction Welcome to the world of ultimate office imaging. Your new scanner will help improve the professionalism of your documents by allowing you to input quality images as well as electronic text into your computer system. Like all of our products, your new scanner has been thoroughly tested and is backed by our reputation for unsurpassed dependability and customer satisfaction. [. . . ] For example, if you scan a Grayscale image at a resolution of 150, the hard disk space needed to scan a letter size document will be approximately 2. 6 MB. For a listing of what resolutions you should use with each mode, see the end of this chapter and Scanning Hints. Scale Scale is for adjusting the size of scanned images. For example, when scanning to an image-editing program, you can preadjust how big, or how small the image will look after it enters your system. The scale can also depend on what resolution you have your display set at, and the scan resolution. Brightness and Contrast Brightness is the amount of light that is concentrated onto a document while it is being scanned. Adjust the brightness by sliding the button located between the arrows either left or right. Turn the brightness down if characters are thick and dark, and up if characters are thin. Contrast adjusts the tonal range of an image by lowering mid-tone values and increasing values for high and low tones. For example, use contrast to eliminate noise or shading on Grayscale scans or to lean-up" RGB Color scans. 21 Chapter IV Inverse When inverse is checked the colors of an entire image, or portions of an image will become reversed. A color image reverses using additive colors. TWAIN Menu Options Most of the menu options are considered advance features. We strongly suggest that you first become familiar with scanning and using the Control Panel before attempting to use any of the following features. Once you become comfortable with how our scanner works, and how to create clear images, you can begin experimenting with the advance features of the TWAIN dialog box. File Menu Item There are 5 choices located under the File menu item. Please read through the following descriptions to learn how to use the file menu options. If you have any further questions about any of the items located inside the file menu, click on Help located inside the TWAIN dialog box to see more information. Save Settings is for saving changes that you make within the TWAIN dialog box. For example, if you change the resolution, brightness or any other attributes, save the changes by choosing Save Settings. As an example: You can set various resolutions and scan 22 Chapter IV modes and save them as a custom name (i. e. , 75-dpi color 200 scale). The factory default is set to RGB and 50 DPI and 50% for brightness and contrast. Settings Files allows you to change the names, or delete settings that you set up and define. Note: Once you change, or delete a setting, you can not recover it, so please be cautious! Filters Menu Item You have 7 filter choices located under the Filters menu item. The filters will help you improve your scans by allowing you to sharpen images and remove excessive dots and distortion. Please read through the following explanations and examples to learn how to properly use filtration. In many cases you might find that experimentation is an excellent way of determining which filter will work. [. . . ] You should keep the receipt as it establishes Proof of Original purchase.
