If you couldn't locate these two commands, please check other menus for them. For best results, make sure the Document Cover is closed before performing scanning. 3 There are four property pages available in the TWAIN source window: Main page Advance page Preference page About page Main Page This page lets your scanner work in the basic mode. All the control settings available here are fundamental to the scanning process. These settings include scanning destination, scan mode, filter, resolution, brightness, and contrast. The Main page window is shown as follows. Property pages You can select any property page by clicking the page tag. Ruler Switch Click here to switch among ruler units. Ruler Three measure units are available: Inch, Cm and Pixel. Scanner Control Settings Scan Rectangle You can define the image area that will be comprised in the final scan. Preview Window You can preview the prescan image. The maximum size of the preview window is A4. 4 Control Buttons Settings in Main Page Destination Destination is the location where you want your final scanned image to be sent. There are six options available: Application, Disk, Printer, Mail, Fax, and Clipboard. Send to Printer This selection lets you send your scanned image directly to the printer for a printout. Send to Application Click this button to send the scanned image to your application program. Send to Fax This lets you send your scanned image to other people through fax.

Please go to the Preference page to set up the e-mail address. NOTE Make sure that the MS Exchange, MS FAX, Modem and its driver are setup properly. Please refer to Microsoft's web site (http://www.microsoft.com) for instructions about setting MS Exchange and MS FAX. 5 Scan Mode Scan mode lets you decide how the scanner will interpret your image. Three choices are available in the TWAIN source: Color mode, Gray mode, and Black/White mode. Gray mode Select Gray mode for images that contain 256 shades of gray. Color mode Select this for 24-bit color images. Line Art mode Select Line Art for texts and illustrations that contain only black/white without gray shading. Filter Filters are provided to produce dropout effects, i.e., to drop the part of the image that is in a color difference from the specified filter. Four options are available: True gray, Red, Green, and Blue filter. Green Filter True Gray Filter Blue Filter Red Filter Please note that the filter option will be unavailable if you select the "Color mode" in Scan Mode. The disablement of the filter is shown as follows. 6 Resolution The resolution is measured in dots per inch (dpi), which is used to represent the image detail in a given area. The available resolution ranges from 50 to 19200. Generally, the higher the resolution is, the sharper and higher the quality of the scanned image gets. However, in some cases, high resolution is not necessary because resolution is determined or limited by many factors: image type, the original image's resolution, the output device's resolution, the available memory space in your hard disks, etc. Pointer Edit box You can adjust the resolution by dragging the pointer to the desired resolution , directly key the value in the Edit box, or choose the value by clicking on the pull-down button. Brightness Brightness refers to the intensity of light reflected from or transmitted through an image. The larger the brightness value, the brighter the image appears. You can either drag the pointer, key the value into the Edit box to change the value, or choose the value by clicking on the pull-down button. Contrast Contrast refers to the differences in the brightness between the light areas and the dark areas of an image. The larger the contrast value, the higher the differentiation between the light and the dark areas.You can either drag the pointer, key the value in the Edit box to change the value, or choose the value by clciking on the pull-down button. 7 Control Buttons in Main Page Scan Button Click the Scan button to perform the final scan and send the result to the destination determined by you. Prescan Button Click the Prescan button to perform a prompt low-resolution scan. The prescan image will be displayed in the Preview window. Help Button Click this button to get on-line help. Exit Button Close this TWAIN source window. Reset Button Click this button to return to the default setting. 8 Advance Page While including the basic functions of the Main page, the Advance page also encompasses image enhancement tools that can be used to compensate for any color distortion of the scanned image. The Advance page is illustrated as follows. Preview Window Image Enhancement Tool Size Press the right mouse button in the preview window, and a rectangle box with a list of sizes will pop-up. Please select one of them and press "Scan" directly. Scan Control Tools ( the same as Main page) Image Enhancement Tools ­ Image Box Mirror Descreen HSV Auto Color Control Color Correction Zoom Invert Gamma Tone Adjustment 9 Zoom The Zoom command allows you to enlarge the view of an image in the Preview window. However, the zoom function can only enlarge the image view with one defined scale. To zoom in: Click the Zoom command. It will magnify the view in the Preview window. To disable zoom in: After magnifying the view, click the Zoom command again to reduce the view to its original size. NOTE: When zooming in, a vertical scroll bar and/or a horizontal bar will appear to let you scroll through the entire image. Mirror Mirror command lets you change the horizontal orientation of a prescan image to one that mirrors the current orientation of the image view across a vertical imaginary line. To mirror an image: Click the Mirror command in the Image box. Invert The Invert function enables you to make a positive view of a scanned image negative or to make a negative image positive. By applying this command, the brightness value of each pixel will change to an inverse value on 256-color scale. To invert an image: Click the Invert command from the Image box after applying the Prescan function. 10 Descreen Descreen filter is used to eliminate the moire patterns (wavelike lines) from the images. As the images are scanned directly from screen-print media (like newspapers or magazines), you should notice that the scanned images usually come with wavelike patterns and banding lines. As long as the scanning resolution is not set very high, you can apply this function to remove those annoying effects. (When this function is activated, the scanning speed will become slow.) Click on the descreen icon, and a dialog box titled "Descreen" will appear. There are three items in the top dialog box: Normal Scan, Default Setting and Customize. Select "Normal" then descreen will not perform onto the scanned images. Select "Default" to perform the default setting of various document types. In addition, select "Customize" to define your own descreen level by entering a desired value in the number box. Gamma Sometimes you wish to adjust the brightness of midtones of the scanned image while keeping shadow and highlight areas relatively unchanged. The Gamma correction function allows you to increase or decrease the intensity of the middle gray tones. The available gamma value ranges from 0.01 to 7.99. The default value is 1.0. Changing the gamma value above 1.0 will brighten the midtones, while below 1.0 will darken the midtones. You can either enter the desired gamma value in the edit box or use the scroll bar to select your desired value. 11 In the "Channel" checking box: All To correct all color components (red, green, and blue) of the image with the same gamma value. Red To correct red component of the image. Green To correct green component of the image. Blue To correct blue component of the image. If channel "All" is chosen, the gamma value is applied to all the red/green/blue channel. Otherwise, gamma value for red/green/blue is applied to red/green/blue component respectively. HSV Choose the HSV command from the Tools menu. The Hue & Saturation dialog box will display and allow you to adjust the hue and saturation of its pixels in an image while the brightness level remains unchanged. Hue is the wavelength of light reflected directly from an image and it is represented by the name of colors. The adjustment of the hue will change the whole color appearance ...
