Checking connections
The scanner can be connected to the computer using a USB or a SCSI connection.
USB is recommended because its installation is simpler.
If you are having trouble with a USB or a SCSI connection, use the Apple System
Profiler to verify that scanner is connected to the computer correctly.
Using the Apple System Profiler
The Apple System Profiler is a tool included in the Mac OS that provides information
about your computer, such as:
● the version of the Mac OS your computer is using
● the number and type of peripheral devices that are connected to your computer
● what programs are installed on your computer
If you are still having trouble with USB after using the Apple System Profiler, see
“
Checking the USB connection ” below. If you are still having trouble with SCSI, see
"Checking the SCSI connection" on page 16 .
To open the Apple System Profiler
1 Choose Apple System Profiler from the Apple ( ) menu.
2 Click the Devices and Volumes tab.
3 Make sure the scanner is listed in the USB section or the SCSI section of the
window with the other USB and SCSI devices connected to the computer.
