The AFHCAN software provides a means for activating the TWAIN driver and for handling the
image that the TWAIN driver returns. To scan an image, press the
Scanner
button on the
Add
To Case
screen. Figure 12 shows the initial
Scanner
screen. Table 7 shows the buttons on the
Scanner
screen and describes their functions.

Button Function
Pressing the
Scan
button activates the TWAIN driver and initiates a scan.
The
Scan
button is used for scanning documents where a high-contrast,
black-and-white image is desired. When the
Scan
button is used to initiate a
scan, the software forces each pixel in the image to either 100% black or
100% white. This enhances the contrast for documents like forms, but
removes shading information needed for photographic images. The resulting
image file will be somewhat compressed, meaning it requires less memory and
takes less time to send and receive. The
Scan
button can be pressed
repeatedly to scan additional items. Each scan will be stored as a thumbnail
on the
Scanner
page.
