6.1 PROBLEMS DURING INSTALLATION
(1) Configuring the IP address gives a communication error.
[Check 1]
Check that the L/A LED on the PR-LN4 is correctly lit up.
- Is the printer turned on?
- Check that the network cable is connected correctly.
- Check that the port on the Ethernet hub is not faulty.
[Check 2]
Check that an IP address is assigned to the computer where the settings tool is running.
- In order to check whether communication can be established between the computer you are using and
other computers on the network, execute the ping command from the MS-DOS prompt.
*1)
For details on how to use the ping command, refer to [Check 1] in "Problems in the Windows TCP/IP Environment".
[Check 3]
Check whether the PR-LN4 has been initialized.
- For details on how to restore the PR-LN4 to the factory default settings, refer to "5.3 PR-LN4 WEB
PAGE MENU STRUCTURE " - "Factory default" in "5 CONFIGURING USING A WEB BROWSER".
[Check 4]
The PR-LN4 may be configured with an invalid IP address.
- Check that the router and server are not configured with an invalid IP address.
- For a PR-LN4 configured with an invalid IP address, create a network that does not have any routers or
servers (a local network consisting of 1 computer, 1 hub, and the PR-LN4 connected to 1 printer),
configure the computer to have an IP address within the same segment as the PR-LN4, then run the
tool to change to [Specify an IP address] in the TCP/IP settings and configure a correct IP address.
After this, restore the original network.
*2)
If you have any routers or servers configured with an invalid IP address and the TCP/IP setting in the PR-LN4 is set to
[Automatically acquire an IP address], the PR-LN4 will automatically be set to an invalid IP address, and you will not be
able to change or initialize the IP address.
