3. REQUIREMENTS & SOFTWARE INSTALLATION To run the scanner at rated speed recommended , you must have the following minimum requirements: l IBM compatible PC 586, Pentium or higher l Microsoft Windows 98 / 98SE / Me / 2000 / XP l One SCSI card installed on your computer; l 100M bytes of available hard disk space for installation; l 128M bytes of RAM l A CD-ROM drive. Scanner driver Installation : 1. 2. Start your PC and Windows application. Insert the scanner bundled CD to your CDROM drive.
3. The software installation graphic should appear as below: If not, press the Start button, choose RUN ,and type d:\driver\twain driver(or isis driver)\setup.exe (d means the letter indicating your current CD-ROM drive). Click on the OK button. 4. Follow the subsequent instructions on the screen to complete the driver and application installation.
3.1 USER INTERFACE OPERATION 1. Open your scanning application. 2. Pull down the File menu and choose Select Source. If the Select Source command is not available on the File menu, see your application’s user’s guide to determine how the TWAIN/ISIS link is used. A dialog box with a list of scanning sources appears. 3. Select Avision Scanner/32Vx.xx. You need to select the source only once, unless you want to choose another scanner. 4.
6. Select the scanning method you want to use on the Scan Method drop-down menu. 7. Select the mode you want to use for your scans on the Image Type drop-down menu. 8. Select a scanning resolution on the Resolution drop-down menu. 9. Select the settings for the scanning features (e.g., Sharpen, Descreen, etc.) that you want to use. 10. Click on the Preview or Scan button to preview or scan your document(s).
4. USER INTERFACE 4.1 SCAN METHOD Select how you want to scan on the Scan Method drop-down menu. Simplex/One-page— use this setting if you are using the automatic document feeder (ADF) to scan a single-page document at a time. Simplex /Multi-page— use this setting if you are using the automatic document feeder (ADF) to scan batches of single-page document at a time. Flatbed— use this setting if you are using the flatbed to scan one page at a time.
4.2 DETERMINING YOUR RESOLUTION A good control of the resolution results a satisfactory detail of an image that scans. The resolution is measured by dots per inch(dpi). Normally, the greater the dpi number, the higher the resolution and the image file size. Be aware that the greater resolution takes more time, memory and disk space, therefore, up to a certain degree of dpi, the resolution will not visually be improved, on the contrary, it makes your files more unmanageable.
Tips: 1. For your information, an A4 size color image scanned at 300 dpi at True Color mode consumes approximately 25 MB of disk space. A higher resolution (usually means over 600 dpi) is recommended only when you need to scan a small area at True Color mode. 2. You can also refer to the following table to choose a proper resolution while applying your image to other application.
4.3 SELECTING A PROPER IMAGE TYPE Select image type through the mode from the scanner user interface for your own purpose. Each image type is described as follows: Line art(Black and White) LineArt presents the image in black and white only and there are no intermediate shades of gray in between. That means each pixel of the image is 100% black or 100% white. LineArt is the best choice of image type if you want to scan text, pen or ink drawing.
Lineart Image *Pixel: A combination of two words: picture and element, a pixel is a single dot on a computer display or in a digital image.
Halftone In addition to the black and white display, Halftone simulates gray scale by using different size of dots. Particularly when you view the image at a certain distance, it looks very closely like a gray image yet it consumes the least disk space. Halftone is the picture that we usually see in newspapers or magazines. Since Halftone is one type of black and white image, the disk space required to save a halftone image is 1/24 of that required to save a 24-bit true color image.
8-Bit Gray A single-channel image consists of at least 256 shades of gray. An 8-bit scanner produces a grayscale image with 1024 shades of gray between pure black and pure white. Choose this option if you are scanning blackand-white photographs. With 8 bits of color information per pixel, the file size of an image is eight times larger than a Black and White image and 1/3 the size of a 24-Bit Color image.
8-Bit Color an 8-Bit Color image provides 256 color hues in the image. The file size of a 256 color image is 1/3 the size of a 24-Bit Color image. 8-Bit Color Image 24-Bit Color A 24-Bit Color image consists of three 8-bit color channels. The red, green, and blue channels are mixed together to create a combination of one billion colors which give a more true-to-life quality to the image. Choose 24-Bit Color if you are scanning color photos.
4.4 ENHANCING YOUR IMAGE Brightness: Adjusts the lightness or darkness of an image. The higher the value, the brighter the image.
4.5 CONTRAST Adjusts the range between the darkest and the lightest shades in the image. The higher the contrast, the bigger the different gray scales.
4.6 INVERT IMAGE The invert command reverses the brightness and the color in the image. For color images, each pixel will be changed into its complementary color at the command of Invert.
4.7 MIRROR Click on the Mirror button to reverse the image (create a mirror image).
4.8 PREVIEW AUTO-AREA: Clicking on the Preview Auto-Area button automatically crops the preview scan area to the previewed document. This will then be the cropping area for all of the scanned documents. 4.9 PAPER SIZE: Select a size on the Paper Size list of frequently used scan sizes, including business card, 5 x 3 in., 6 x 4 in., Letter, Legal, B5, A5, A4, A3, or your current scan area to perform an immediate selection of your scan size. 4.
Before Descreen After Descreen *Moiré pattern— an undesirable pattern resulting from the incorrect screen angle of the overprinting halftone. 4.12 SHARPEN Click on the Sharpen button to access a dropdown menu that allows you to specify a level to sharpen the scanned image. You can specify a Sharpen setting of Light, More, Heavy, or Extra Heavy. 4.13 COLOR ADJUSTMENT Click on the Color Adjustment button to enable the button for the Hue, Saturation, and Lightness feature.

Highlight / Shadow This feature is available when 8-Bit Gray, 8-Bit Color, or 24-Bit Color is selected on the Image Type drop-down menu.
Use the Highlight and Shadow settings together to extend the range of color and reveal more details in a color image.
Curves When you select the Curves button, a dialog box appears that allows you to adjust the midtone of the image without losing details in the lightest and darkest areas. Select the Curve or Line button, depending on if you want a curved or an angled setting. Place the mouse cursor over the line, click the right mouse button, and drag the line to set the curve you want.
The default parameters are used to adjust the image. You can type values in the Color Levels text boxes or you can drag the sliding arrow under the color.
