●Do not connect both a USB interface and a SCSI card at the same time.
●Note the following points when using the USB interface that was provided as
standard with your computer.
• Use the most recently available USB 2.0 driver provided by Microsoft. Contact your
local authorized Canon dealer for more detailed information.
• Not all USB interfaces provided as standard with personal computers are guaranteed.
Contact your local authorized Canon dealer for more detailed information.
• 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 bundled with the scanner
or a Hi-Speed USB 2.0 compatible cable.
●Note the following points when using a SCSI card.
• Be sure to use the procedure in the manual for the SCSI card and the computer
that you are using when installing a SCSI card in your computer.
• The overall length of the SCSI cable you can use is determined by the SCSI
standards. Refer to the manual for the SCSI card you are using for more information.
• When using the ASC-19160 SCSI card in Windows XP, make sure that your driver
version is 6.2.0.0 or later. Download the driver from the Adaptec Web site if
necessary.
●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 scan settings.
●The ISIS/TWAIN Drivers provided with the scanner do not necessarily operate on all
ISIS- or TWAIN-compatible applications. For details, contact your application
software retailer.
