manufacturer of the computer for more information.
• If you use the scanner with Windows, use the latest USB 2.0 driver
made available by Microsoft. For details, consult your local
authorized Canon dealer.
• Use the USB interface provided as standard with your computer.
However, normal operation is not guaranteed with all USB
interfaces, even if present as standard equipment on the computer.
For details, consult your local authorized Canon dealer.
• Scanning speeds are lower if your computer's standard USB
interface is USB Full-Speed (equal to USB 1.1.)
• The USB cable you are using should be the one originally included
with the scanner.
• If the CPU, memory, interface card, and other specifications do not
satisfy the installation requirements, the scanning speed may be
greatly reduced and transmission may take a long time.
• Even if the computer satisfies the recommended specifications, the
scanning speed may vary, depending on the specified scan
settings.
• The scanner drivers provided with the scanner do not necessarily
operate on all ISIS or TWAIN-compatible applications. For details,
contact your application software retailer.
Precautions for Use in 64-bit Operating Systems
• The ISIS/TWAIN driver supplied with this product supports
scanning with 32bit applications only.
• Even with 32-bit applications, not all ISIS/TWAIN compliant
applications are guaranteed to operate.
• Scanning speed may vary depending on the specifications of your
computer.
