systems):
1
Refer to basic installation troubleshooting. See "Performing basic installation
troubleshooting" on page 10.
2 If the power connection is secure, but the software does not find the scanner,
check for a device conflict. See
"Check for a device conflict" on page 17 .
3 If you have checked for a secure power connection and for device conflicts, and
the software still does not find the scanner, check for a resource conflict. See
"Check for a resource conflict" on page 18 .
4 If you have checked the power connection, device conflicts, and resource
conflicts, and your scanner is still not working, check the parallel port settings.
