Setup
2.1 Installing the Scan Driver
At the beginning of installing ScantoolsTM (the image processing
software that comes with the scanner), if you choose to install
device drivers, the "Installing Device Drivers" dialog box will
appear with a list of drivers for you to choose. Highlight the
driver that corresponds to your scanner model and click the
"Install" button.
2.2 Installing the Interface Card
Figure 2 The 16-bit Interface Card
Note
If you use the parallel port adapter, you don't need to install this interface
card.
The interface card uses four continuous I/O address es to
control the s canning process. The relationship between the I/O
switch setting and the actual I/O addresses are as follows:
4
SW1 SW2 SW3 SW4 I/O Address
on off off off 150~151
off on off off 170~171
off off on off 350~351
off off off on 370~371
Only one switch can be set to ON at one time. All othe r
setting combinations are invalid.
To install the interface card, proceed as follows:
1. Turn off your computer and al l peripherals.
2. Remove the computer case as illustrated in Figure 3.
Figure 3 Figure 4

3. Position the computer so that you have a clear view of the
mainboard and its expansion slots. If your computer is a
tower model, first lay the computer on its side with the
mainboard facing up. Choose any unused 16-bit expansion
slot to insert your interface card.
4. Remove the metal plate on the computer case that covers
the opening of the expansion slot you plan to use. You may
need a screwdriver to do this.
5. Remove the interface card from its protective package.
6. Insert the card into the slot (s ee Figure 4 above). As you
insert the card, always keep the card at a 90° angle to th e
mainboard with i ts golden fingers aligned with the slot. Pus h
the card in firmly .
7. Use the screws to secure the mounting bracket of the
interface card to the computer case.
8. Replace the computer case.
2.3 Connecting the scanner
1. Make sure your system is off.
2. Align th e plug (connector) of the scanner cable with the
socket on the interface card. A small arrow on the plug can
help you with the alignmen t (see figure 5).
3. Push the plug in firmly to make a secure connection.

Chapter 3:
Launching the Image Source
(TWAIN)
Before using your scanner, you have to launch an image source
to connect the application and the scanner. The connection
allows the application and the s canner to understan d each
other so th at the application can direct the scanner to
accomplish th e desired scanning tasks.
TWAIN is such an image source, which is the most popular one
and has become an industry standard.
The Handy Scan Colour is TWAIN-compliant. Therefore, you
can use the scanner with any application software that supports
TWAIN.
We will be using ScantoolsTM, a TWAIN-supporting image
processing application, to explain how to launch the image
source.
1. From the "Scan" or "File" menu, choose "Select Source."
The "Select Source" dialog box appears. Highlight the
TWAIN Source you want to use and click the "Select"
button.
2. From the "Scan" or "File" menu, choose "Acquire". Now you
are ready to use your scanner.
Note
Other applications may include the "Select Source" and "Acquire" commands
in a menu other than "Scan" or "File" menu

the shadow and highlight parts unchanged.
You can specify a gamma value in the range from 0.01 to 7.99.
The original image has a gamma value of 1.0. A gamma value

Chapter 5:
StitchScan
The StitchScan option is a marvelous feature that compensates
for the scanning width limitation of the handheld scanner. The
compactness and portability that make the handheld scanner
"handy" also limits the scan width of the scanner.
Yet with this StitchScan feature, the scanner is allowed to scan
big images of any size. You can scan the big image one portion
at a time and then stitch these portions back to an intact copy
of the original image.
TWAIN sou r ce allows you to stitch images in three different
ways: Manual Stitch, Semi-Auto Stitch and Auto Stitch.
If you choos e Manual or Semi-Auto stitch, after you have
finished scanning the second image, the following Stitch
window will appear with the first and second image displayed
inside the window:
The menu bar of this window contains three menus: Stitch, Edit
and View, each includes several commands to help you
accomplish the Stitch function.
The Toolbar contains several buttons which act as shortcuts to
some frequently used menu commands.

4. Gamma Correction 8. Preferences
After you have manually or semi-automatically matched the
distinct features in the two images, click on the "Do Stitch"
button or select the "Do Stitch" command from the Stitch menu.
The two images will be stitched into one as illustrated in the
following fig ure:

If you have chosen "Auto Stitch" instead, the stitch window will
appear. Rather the stitching will be automatically carried out
after the two image portions h ave been scanned and the
resulting "stitched" image will be displayed inside the
Scan
Window
(not stitch window) of the TWAIN Source window.
