Note: If a button is not pre-configured (for example, if your computer does not have fax software installed so FAX cannot be pre- configured), a dialog box appears to remind you to configure that button manually. Follow the steps in “Changing a Scanner Button’s Settings” to configure the button.

You can change the setting of any of the scanner’s buttons using the Scan Buttons Setting dialog box. This dialog box displays a list of options and settings for customizing the scanner.

1.Click on the windows taskbar and click on Scanner Buttons Setting. The Scan Buttons Setting dialog box appears.

2.Right-click on the icon for the desired scanner button to view the current set- ting.

3.Adjust the scan and page settings for the buttons as follows.

Scan Mode — Select Black/White to scan in black and white. For example, letters and memos are usually scanned in black and white. Select Grayscale to scan objects containing drawings or black-and-white photographs. The scan- ning produces an image in varying shades of gray. Select Color to scan color photographs and other color objects.

Scan Size — Choose one of the page sizes from the drop-down list. The out- lines on the picture represent the vari- ous page sizes. Clicking on one of those outlines also selects it as the page size for the scan. If you select the Custom option from the drop-down list, boxes appear in place of the picture. Enter the width and height dimensions for your scan in those boxes.

Resolution — Choose from the drop- down list to adjust the dots per inch (DPI) of the resolution. The maximum resolution is 4800 DPI, the minimum is 50 DPI. The higher the DPI setting, the sharper and clearer the scanned image. However, higher DPI settings take longer to scan and produce larger files for the scanned images.

Brightness, Contrast and Threshold

— Drag the sliders to the left or right to adjust the brightness, contrast, and threshold (the intensity point at which a scanned object is determined by the software to be dark or light).

4.Click OK. The new configuration and its adjusted settings are applied to the but- ton.
