• If you do not know the requirements for your computer system, 

contact the store where you purchased the computer or the 
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 (only for Windows) or TWAIN-compatible 
applications. For details, contact your application software retailer.

• The scanner 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.

On a Macintosh computer equipped with a PowerPC CPU, the 
scanner driver of this product cannot be used with Classic 
Environment.
The driver will not run correctly when Classic Environment is running 
so use the scanner when Classic Environment is not running.
