A-2
Appendix B Specifications
*1 Load A4-size documents in the Landscape (horizontal) orientation.
*2 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.
*3 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
*4 Including data-transfer time
The following system was used to measure the scanning speeds.
• CPU: Pentium 4, 3.2 GHz or better
• Memory: 1 GB or more
• Interface: USB 2.0
The scanning speeds may be slower depending on the PC system used.
*5 Only when the power supply is 100 to 120 VAC.
