16 Installing and troubleshooting
If the parallel cable still does not work, follow these steps (all operating 
systems):
1 Refer to basic installation troubleshooting. 
2 If the power connection is secure, but the software does not find the scanner, 
check for a device conflict. 
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. 
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. 
5 If the troubleshooting information you need is not shown here, refer to the HP
