How to Use This Guide
This User’s Guide provides instructions and illustrations on how to install and
operate your scanner. This guide assumes the user is familiar with Microsoft Windows
XP and 2000 Professional. If this is not the case, we suggest you learn more about
Microsoft Windows by referring to your Microsoft Windows manual before using your
scanner.
The Introduction section of this manual describes the box contents and minimum
computer requirements to use this scanner. Before you start installing your scanner,
check the box contents to make sure all parts are included. If any items are damaged
or missing, please contact the vendor where you purchased your scanner or our
customer service directly.
Chapter I describes how to install scanner’s software and connect the scanner to
your computer. Note: The scanner connects to your computer through the Universal
Serial Bus (USB). If your computer does not support USB technology, you will need to
purchase a USB interface card to add USB capabilities to your computer, or buy and
install USB connectors if your motherboard has USB capabilities. This guide assumes
that your computer is USB-ready and has a free USB port.

Chapter I. Installing the Scanner
Before installing your scanner, please verify that you have all of the proper
components. A list of the package contents is provided in the Box Contents section of
this guide.
Software Installation Requirements
Your scanner comes with the image-editing software, OCR software, document
management software, the scanner’s driver, and the DigiDoc software. All of these
software applications use approximately 400 megabytes of hard disk space after they
are installed into your computer. To ensure ample room for the installation, as well as
for scanning and saving images, a minimum of 550 megabytes of hard disk space is
recommended.
The USB scanner can only operate under the Microsoft Windows 2000
Professional and XP operating system or Windows Vista.
Attention
Please do not use multiple USB scanners in Windows XP
simultaneously! For more information, please refer to the following
URL...http://www.microsoft.com
Hardware Requirements
This scanner connects to your computer through the Universal Serial Bus (USB),
which supports hot Plug and Play. To determine whether your computer is USB-
capable, you must check the rear of your PC to locate a USB jack that looks the same
as the one pictured below. Note that on some computers, the USB port at the rear of
the computer may be occupied and additional ports may be found on the monitor or
keyboard. If you are having trouble in locating the USB port on your computer, please
refer to the hardware manual that came with your computer.
Upon examination, you should find one or two rectangular USB ports, which
usually appear as shown below.

USB Connector(s)
If you don’t find such USB ports on your computer, then you need to purchase a
certified USB interface card to add USB capabilities to your computer.

A
ppendix A:
Troubleshooting” section of this manual and follow the instructions

Software Setup Troubleshooting
Carefully review the steps outlined in this guide and the Quick Guide that
accompanied your scanner.
If you are still having problems, please check that:
 You have 550 MB of free space on your hard disk drive.
 The scanner is plugged in and has power.
 You are using the USB cable supplied with the scanner.
 The square end of the USB cable is plugged into the rear of the scanner.
10

 The rectangular end of the USB cable is plugged into the back of your

please make sure that it conforms to the TWAIN standard.

Chapter II.
Usage and Maintenance
Your scanner accepts documents as small as business cards and as large as
Legal size documents. However, some software programs have limitations as to the
information they can handle. The capacity of the computer’s memory and free space
on your hard drive can also limit the physical size of the document that you scan.
There are two different ways to operate the scanner:
1. From within an image-editing program that can acquire images from the
scanner.
2. By pressing either of the two action buttons on the scanner. You may
configure the button settings individually to your personal needs within the
DigiDoc program that is automatically installed as your scanner software.
Your scanner needs to be driven by certain type of software program. Since all
documents or images (whether text or pictures) that are acquired from the scanner are
treated by your computer as images, most scanning will probably be done from an
image-editing program where you can view, edit, save and output the scanned images.
An image-editing program has been bundled for your scanner on the included
Setup/Application CD-ROM. It will allow you to alter and correct any scanned images
by using a variety of filters, tools and effects.
What about scanning text documents and editing them in a word processor? This
is the role of Optical Character Recognition (OCR) software. OCR software converts
the image files that are created from scanning text documents into text files that can be
viewed, edited and saved by word processors. An OCR program has also been
bundled on the included Setup/Application CD-ROM, and if you wish to use the
scanner in this way you should install the OCR software that is included.
DigiDoc is an amazing program that allows you to conveniently scan plastic cards
and document without the need to work directly within any image-editing application (i.e.
Presto! ImageFolio). DigiDoc not only includes features to allow you to use your
scanner as a copy machine4and to scan documents or photos for e-mail, but also
includes features to allow you to choose continuous scan or not freely. With DigiDoc,
you would enjoy your scanning happily.
4A printer is required for the copy function.
12

DigiDoc
You may configure the scanning properties for each individual scanner button
within the DigiDoc window.
There are two ways to access the DigiDoc window:
1. Double-click the DigiDoc icon in the Windows system tray.
2. Single-click or right-click the DigiDoc icon in the Windows system tray, and
then choose Setting in the pop-up menu that opens.
The DigiDoc program comprises several scanner button functions. More than that,
if you have installed the bundled software (e.g. PageManager) to your system, the
DigiDoc program may enable more functions. (Refer to the section of “Using the
Scanner Button”.)
Attention
Changes you make in the DigiDoc window are automatically saved
immediately after you close the DigiDoc window. Afterwards, with a
single touch of the button, you can have the scanner complete your
scanning jobs by the settings you configured within the DigiDoc window.
If you decide to quit DigiDoc program entirely, the same settings can be
enabled for your quick access next time you open the DigiDoc window.
Configurations
First, you should select LED1 to 9 tab to define which LED tab you want to
configure.
