Troubleshooting – Macintosh
5. You may have to remove SCSI devices with DB-25 connectors.
6. You may need to contact the vendors of your other SCSI devices to determine
if they are internally terminated. Generally, you should not have more then one termi-
nated device on your SCSI chain. Certain devices and arrangements may require more
then one terminator. However, these instances are rare.
You should contact Nikon Technical Support if you are experiencing severe diffi-
culty and have worked through the preceding corrective steps without success.
• Problem: The scanner is not found by the Nikon Scanner plug-in.
Action: Attempt to locate the scanner on the SCSI bus by first clicking on the
Tools icon. Once inside the Tools dialog, attempt to manually address the scanner by
clicking on the SCSI icon and the A
mined the scanner's SCSI address, set that address in this dialog, click the D
then set the scanner's defaults.
• Problem: The plug-in fails to find the scanner when I click F
Action: Proceed with the following corrective action:
1. You may need to power on all of your SCSI devices before starting your com-
puter. If this fails to correct the problem, the scanner may be defective, or you may have
a rare conflict on your SCSI bus.
2. You may have two SCSI devices set to the same SCSI ID number, such as the
Nikon scanner and an external hard drive. Make sure that no two SCSI devices are set
to the same SCSI ID number.
3. Try starting your Macintosh with the Shift key held down (System 7) in order
to disable all of your Extensions. Then, try using the scanner. If the scanner functions
normally, you should examine the contents of your Extensions and Control Panel fold-
ers to make sure that you don't have outdated or incompatible software. "Inits" used
with some removable cartridge drives may cause SCSI difficulties. Some utilities that
display the active drive number may also cause problems.
It is best to start with nothing but Apple-issue system files installed. Have your
scanner up and running, then start reinstalling your accessory files. You may need to
change the order in which these files are loaded. You can do so by adding an "A" or a
"Z" to the very beginning of the file name to change the loading order (Apple system
software loads these files in alphabetical order).
