Installing and troubleshooting 21
Windows NT 4.0:
1 On the Start menu, point to Programs, point to Administrative Tools 
(Common), and click Windows NT Diagnostics.
2 On the Resources tab, check the numbers in the I/O Port and Resources 
areas. Verify the numbers listed against the numbers in your computer 
documentation.
3 If the scanner still does not work, see "If the parallel port still does not work, 
follow these steps (all operating systems):" below.
If the parallel port still does not work, follow these steps (all operating 
systems):
1 Turn off the computer.
2 Unplug the scanner power cord, and then plug the scanner power cord back in. 
(Do not unplug the scanner without first turning off the computer.)
3 Turn on the computer.
4 Set the parallel port mode to EPP or ECP. This might be required when the 
computer has a BIOS setting that interferes with the driver negotiation to 
operate in EPP mode. For information about how to use the BIOS to set the 
parallel port mode, see the documentation you received with the computer.
For more information regarding these settings, see the documentation provided with 
your computer.
