cursor. To cancel the function, click the
manual-focus button again.
Click on the area of image to be used for
focus. The focus meter window will appear.
Adjust the slider using the mouse until the
black and white bars are at their longest
extension. The black bar indicates the
change in focus. The white bar indicates the

Click OK to set the focus. A new prescan
will start and replace the previous image.
The scanner can be focused manually using the focus meter. For best results, select
an area within the image with contrast or detail. The manual focus functions cannot
focus on a low-contrast image such as a cloudless or overcast sky.
