1. OVERVIEW
1. OVERVIEW
1.1 Features
600-dpi optical resolution for high-precision image scanning
Scanning with an optical resolution of 600 dpi allows even complex and difcult-to-scan documents,
such as CAD drawings, electronic les, and mapping data to be scanned rapidly and with high precision.
Scanning Master 21+ (scanner software included as a standard accessory) can be used to adjust the
resolution in ve levels (200 dpi to 800 dpi) to suit the scanned document.
Compatible document widths range from 210 mm to 1000 mm
Compatible with document sizes from ISO A4 up to ANSI E
Capable of color and grayscale scanning
Capable of scanning in color (24-bit color, 8-bit color) or grayscale (256 shades)
Capable of reading long-axis data
Long-axis images are supported with a maximum length of approximately four meters each.
Compact and lightweight design
A compact design was achieved by using a document travel system that employs closely-adhered image
sensors in the sensor unit (ve rows arranged in a zigzag pattern).
Image-processing functions
Use of the scanning software provided lets you set image-processing functions for the scanning of a
document.
Interface
The interface conforms to the SCSI-2 standard.

* 1 Documents up to approximately 16 m in length (driver software limitation) can be scanned. However, the actual
document 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 Excluding data-transfer time
* 3 Notes on scanning precision
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.
• Test chart used : Mylar sheet #200
• Guaranteed precision conditions : Temperature 20 ±3˚C; humidity: 60% ±10% RH
• Guaranteed scanning precision range : 1189 mm x 841 mm
• Document hold-down unit setting : Standard

1. OVERVIEW
1.4 System Requirements
The minimum system requirements for running the scanner’s hardware and software are listed below.
Operating system: Windows 95/98/Me, Windows NT 4.0, Windows 2000 or later
CPU: Pentium 133 MHz or higher
Memory: 32 MB or more
Monitor: 1024 × 768 pixels, 256 colors or more
Enough disk space to store data
Mouse
SCSI board by Adaptec
Recommended environment
For binary monochrome data
CPU: Pentium 200 MHz or higher
Memory: 64 MB or more
SCSI board by Adaptec (PCI type)
For grayscale data
CPU: Pentium III 550 MHz or higher
Memory: 256 MB or more
Monitor: 1024 × 768 pixels, High Color or higher resolution
SCSI board by Adaptec (PCI type)
For 8-bit color data
CPU: Pentium III 866 MHz or higher
Memory: 512 MB or more
Monitor: 1024 × 768 pixels, True Color or higher
SCSI board by Adaptec (PCI type)
The system conguration should correspond to the recommended specications listed here, in order to ensure the
optimum capabilities of the scanner.
Use with a system conguration below the recommended specications will affect the scanning speed and prevent
the scanner from operating to its specied capabilities.
To edit an A1-size or larger grayscale document with a resolution of 400 dpi or higher, or an 8-bit color document,
you may need more than the recommended memory sizes above. Depending on the type of document, you may not
be able to scan in the document even if you increase the memory size.
