*1 If the document is a long-length document, the actual length that can be scanned is limited by the available
memory (hard disk or other data storage device) of the computer to which the scanner is connected, and also by
the grade of the medium being scanned.
*2 Notes on scanning precision
The scanning precision may vary slightly depending on the grade and thickness of the medium being scanned,
and on the operating conditions. The precision figures above were measured under the operating conditions
described below.
• Special test chart: Mylar sheet #300
• Guaranteed precision conditions: Temperature: 23°C ±5°C; Humidity: 55% ±15% RH

3.3 System Requirements

The minimum system requirements for running the scanner’s hardware and software are listed below.
• Operating system: Windows 2000 Professional, XP Professional, or XP Home Edition
• CPU: Pentium III, 1 GHz
• Memory: 256 MB or more
• Monitor: 1024 x 768 pixels, True Color or higher
• Disk space: At least 10 GB
• Mouse
• Interface: USB 2.0 interface
*1 When the document length exceeds length of an A0-size document, additional hard disk space is required.
Recommended environment
• CPU: Pentium 4, 2 GHz
• Memory: 1 GB or more
• Disk space: At least 30 GB
• USB 2.0 interface (that comes standard with your computer)
*1
Use with a system configuration below the recommended specifications will affect the scanning speed and prevent
the scanner from operating to its specified capabilities. Moreover, colors may not be displayed correctly if the num-
ber of colors that the monitor can display is 256 or less.
To edit an A1-size or larger grayscale document with a resolution of 400 dpi or higher, or a 24-bit color document,
you may need more than the recommended memory sizes above.
