Main page

This page lets your scanner operate in the basic mode. All the control settings available here are fundamental to the scanning process. These settings include scan mode, scanning destination, resolution, brightness, contrast and scan control button. The Main page window is shown as follows.

The TWAIN source window is divided into three major parts: title bar (on the top), Preview Window (on the left) and property pages (on the right).

Title bar

The title bar displays the name of the TWAIN source. You can move the window around on your screen by positioning your mouse cursor on the title bar. Hold down the left mouse button and drag the window to the desired location, and then release the mouse button. The icons located at the end of the title bar can be used to minimize the window to its smallest size or to close the window.

Preview Window

The Preview Window is where the prescan image is displayed with ruler markings along its edges. You can change the ruler unit by simply clicking the unit box on the upper left corner of the Preview Window. Three ruler unit measurements are available: inch, centimeter and pixel.

On the bottom of the left Preview Window shows the width and height of the selected scan area as well as its size, and the current position of your cursor.

Property pages

You can flip these property pages by clicking the tags on the top. Their functional details are described in the section of each page.

There are four buttons located on the bottom of the Property pages for you to do the basic scanning operation of the TWAIN source window with one simple click. For details, please see next paragraph.

Scan Control Buttons

Four functional buttons, Prescan, Scan, Help, and Exit, are at the lower right end of the page. A tip box will appear to remind you of the function of each button as you locate the cursor on it.

Prescan Button
Click the Prescan button to perform an immediate low-resolution scan. The prescan image will be displayed in the Preview window.

Scan Button
Click the Scan button to perform the final scan and send the result to the destination determined by you. Click the Scan button will prompt you to give a file name for saving your scanned image if you set "file" as your scan destination.

Help Button
Click this button to acquire help.

Exit Button
Close the TWAIN source window.

When placing the material(s) to be scanned on the scanner, press to view the scanned image on the Preview Window. Define the scan areas then press to proceed scanning.

Define the scan areas

To define a scan area, move the cursor to the Preview window when the first prescan is done. Press the left mouse button and drag a rectangle to the desired size. Release the mouse button. Repeat the same step to define more scan areas. To discard the current selection, simply click the left mouse button outside the rectangle anywhere in the Preview Window.

You can move the entire scan rectangle by placing your cursor inside it. When the cursor changes to a four-way arrow, hold down the left button of your mouse and drag the rectangle to the desired location. You can either change the size of the scan area by dragging any of its four edges/corners when the cursor becomes a two-way arrow at the edge of the scan rectangle or directly type values in the Width and Height box to outline the rectangle. These values are measured with the unit specified in the unit box on the upper left corner of the Preview Window.

After reviewing the prescan image, you can use various image enhancement tools to strengthen the look and quality of your final scanned image. Please refer to Advance page for more details.

Main Settings

Object Type

There are many functions in Object Type section. You can make the most of them to acquire the best image quality.As images are scanned directly from screen-print media (like newspapers or magazines), you should notice that scanned images usually include wavelike patterns and lines. As long as the scanning resolution is not set too high, you can use this function to remove these annoying effects. For example, if your scanning image is newspaper material, the scanner will automatically adjust the scanned image to high newspaper quality.

Normal
You need not select this icon if your document is photo or better quality images.

Newspaper
For newspaper document selection.

Catalog / Magazine
For catalog or magazine document selection.

Art Magazine
For art magazine document selection.

User Define Object
Select this icon and a dialog box will appear. You can either enter the desired value in the number box or use the scroll bar.

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 B/W (black/white) mode.

Color mode
Select Color mode for color images.

Gray mode
Select Gray mode for images that contain 256 shades of gray.

B/W mode
Select B/W for texts and illustrations that contain only black and white without gray shading.

Destination

Destination is the location where you would like your final scanned image to be sent. There are six options available: Application, File, Printer, Email, Fax, and Clipboard. Please select one of the destinations before scanning to have the scanned image sent to the desired location.

Send to Application
When this option is selected, the scanned image will be automatically sent to the software application. To edit the image, you must quit the TWAIN program. Note: If you call up the TWAIN source in a stand-alone mode, the Application function is disabled.

Send to File
This option allows you to save your scanned image as a file. After you click on Scan button, the program will ask you to specify a preferred name for the image.

Send to Printer
This option allows you to output your scanned image through a printer. Make sure your printer is connected to the computer and is powered on. Note: if you want to set a different default printer, please refer to the Preference sheet.

Send to Mail
This option allows you to send your email with the scanned image as an attachment. After you specify a name for the image and the scan is done, the program will automatically load the system default mail program. The image is scanned as a bmp format. Note: our program supports Microsoft Outlook Express only. You have to set Outlook Express as the system default mail program, or you will not be able to make use of this function. Refre to the user manual of Outlook Express for further settings.

Send to Fax
This option allows you to send your scanned image to others as a fax message. Note: you must have installed the fax modem driver, or this function is disabled. For further settings, please refer to the user manual of your fax modem. You can not use this function without a
fax modem.

Send to Clipboard
This option allows you to temporarily save your scanned image on the system. After the scan is done, you can open your desired software application and paste the image onto it.

Scaling

Scaling help you to change the size of the scanned image document by clicking the arrow or entering a number in the edit box.

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 dpi. Generally, the higher the resolution, the sharper and higher the quality of the scanned image. However, in some cases, high resolution is not necessary because resolution is determined or limited by many factors: image type, the original image resolution, the output device resolution, the available storage space on your hard disks, etc.

Normally you should choose a resolution that matches the resolution of the output device. The following list is our suggestion:

72 - 100 dpi for CRT Display
72 - 216 dpi for 9-pin Dot Matrix Printer
100 - 400 dpi for 25-pin Dot Matrix Printer
100 - 400 dpi for Facsimile
100 - 600 dpi for Laser and Inkjet Printer

You can adjust the resolution by using the scroll bar (moving the box, clicking the arrow icons or clicking on the space between the box and the icon), directly keying in the value into the number box, or selecting a value in its drop-down combo box to the desired resolution.

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. Brightness is indicated by a percentage ranging from

¡V 100 to +100, and is set to "0" as the default. You can either use the scroll bar (moving the box, clicking the arrow icons or clicking on the space between the box and the icon), key in the value into the number box or select a value in its drop-down combo box to change the value.

For B/W images, adjusting the brightness of a prescan image is actually setting a threshold for the scanner sensors to interpret the scanned data. Data above the threshold will be interpreted as the white area, while data below the threshold as the dark area.

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. Contrast is indicated in percentage ranging from

¡V 100 to +100, and is set to "0" as the default. You can either use the scroll bar (moving the box, clicking the arrow icons or clicking on the space between the box and the icon), key in the value into the number box or select a value in its drop-down combo box to change the value.
