• When cleaning the equipment, always unplug the AC adapter. Otherwise you could  
cause a fire or receive an electric shock.  
• When cleaning the equipment, use a water-moistened cloth that is well wrung out. Do  
not use flammable liquids such as alcohol, benzene or thinners. If a flammable liquid  
enters the inner electrical parts, it may cause fires or electric shocks.  
CAUTION  
• Carefully close the document cover in order not to pinch your hands.  
• Do not press heavily on the document cover. The document glass may break and injure  
you.  
• When not in use for extended periods, such as long weekends, unplug the equipment for  
safety.  
• When transporting the equipment, be extremely careful. Dropping it could cause an  
injury.  
• Wait until the equipment has cooled before placing a cover over it. Otherwise it may  
cause a fire.  
• Do not use the supplied CD-ROM in regular CD players. It produces excessively loud  
sound that may cause hearing damage.  
• Unplug the AC Adapter from the outlet at least once a year, and clean the area around  
the base of the AC Adapter’s metal pins to ensure all dust is removed. If dust accumulates  
in this area, it may result in a fire.

• The supplied cable is approximately 3ft (1m) long. Set up the scanner so that the cable  
reach from the scanner to the electrical outlet.  
• Do not set up in areas where there is an excessive fluctuation in temperature or humid-  
ity. Also do not move the equipment from high humidity areas to low humidity areas.  
Condensation may cause image errors. After moving from high humidity areas to low  
humidity areas, leave the scanner enough time to gradually adapt to the new conditions  
before use.  
• Do not use the scanner in areas subject to direct sunlight. The humidity may rise inside  
the equipment and cause damage or decrease image quality. If you have to use the  
scanner in direct sunlight, make sure to use a thick curtain to block the light.

Connecting to the Computer  
Connect the scanner to your computer using the supplied USB interface cable. The USB interface allows  
three basic configurations. The scanner can be connected directly to the USB connector on the com-  
puter, directly to a USB hub that is connected to the computer, or to a throughput USB connector on  
another device that supports the USB interface. The three configurations are shown below.

Scanner Connected to Another  
USB Device  
1.Attach the PC end of the USB interface cable to the computer’s USB connector, a USB  
connector on a USB hub or the throughput USB connector on another USB device.  
2.Attach the scanner end of the USB interface cable to the scanner’s USB connector (the  
rectangular connector labeled USB on the back panel).  
• Most USB-compatible computers have 2 USB ports. Other devices, such as keyboards, may  
be equipped with an additional USB port. The scanner may be connected to any of these  
ports.

About the USB Interface  
The USB (Universal Serial Bus) interface is a new standard for connecting peripheral devices to comput-  
ers. The USB interface offers these benefits:  
• Accommodates a wide array of devices, including scanners, keyboards, joysticks, printers  
and modems.  
• Provides excellent expansibility, allowing up to 127 devices to be connected to one USB  
controller.  
• Supports two-way communication at speeds faster than a parallel port (12 megabits per  
second versus 1) or a serial port.  
• Supports ‘hot swapping,’ which is the ability to add or remove devices without turning  
off the computer, an improvement over the SCSI interface that makes it easy to share  
devices between computers.  
• Supports true ‘plug-and-play,’ eliminating the need to set IRQ settings, set DIP switches  
or reconfigure the computer’s system each time a peripheral device is added.

• The maximum allowable size for scanning is 8.5 x 11.69 inches (216 x 297 mm), up to A4  
or letter size.  
• This scanner is equipped with an ultra-sensitive scanning unit. Opening the document  
cover during scanning or improperly closing it may not produce proper results. When the  
document cover cannot be closed because you are scanning thick documents, such as  
books, cover the document glass with a dark cloth to prevent ambient light from  
affecting the scan.

How to Use the Start Button  
You can increase the efficiency of scanning  
by making good use of the scanner's start button.  
Start Button  
The Smart Button and ScanGear Toolbox CS  
Pressing the scanner’s start button sends a signal that tells the computer something like “hey, the start  
button's been pressed!” When the computer receives this signal, it starts ScanGear Toolbox CS.  
As explained in the Quick Start Guide, ScanGear Toolbox CS is a software utility that simplifies the  
scanning process. Its default settings include several preset buttons, such as the Save button, which  
automatically initiates a scan and saves the image when clicked. It also has several buttons that can be  
easily set to work with other programs. For example, it can automatically start a program, initiate a scan,  
save the image and load it into the program for editing. Please read the ScanGear Toolbox CS User's  
Guide electronic manual for instructions to set up the buttons.

Scanner Appears as an Unknown Device Not a Scanner  
Cause 1:  
Computer or computer operating system is incompatible with the scanner, or  
the USB interface has not been enabled in the BIOS  
Solution:  
The performance guarantee for this scanner and its software is limited to its  
operation with computers running Windows 98 that are equipped with a  
built-in USB port. Computers running Windows 95 with a USB port on an  
optional expansion card fall outside the limits of the guarantee.  
Computers with operating systems that have been upgraded to Windows 98  
may have the USB interface setting set to Off in the system BIOS. You must  
change the BIOS settings to enable the USB interface. Please refer to the  
manual that accompanied your computer for these instructions.  
Cause 2:  
Solution:  
Incorrectly connected USB cable  
An incorrect connection to a USB hub or another USB device will prevent the  
scanner from working. Check the USB cables to ensure that they are correctly  
attached. (See p. 19)

Power down the computer and peripheral devices.  
Unplug the AC adapter from the electrical outlet.  
Detach the USB interface cable from the scanner.  
Dampen a clean, soft cloth with water and wring the cloth well. Use the  
well-wrung cloth to gently remove dirt and dust. Be particularly careful to  
remove any traces of dirt or liquid from the document glass by wiping it  
with a dry soft cloth.  
• Do not dampen the connectors, ports or other metallic components on the scanner’s back  
panel. Immediately remove any moisture that contacts these components by wiping  
them with a dry cloth.  
• Do not use a sodden cloth or apply a liquid directly to any portion of the scanner. Any  
moisture that enters the interior, the underside of the document glass or the sensors may  
degrade image quality and lead to malfunctions.  
• Never use substances containing alcohol, thinners or benzene on the equipment. Use of  
these substances may deform, discolor or dissolve the casing.
