7. Troubleshooting
Cannot configure the network interface or cannot print from the network.
Step 1
First, check to see if you can print out the Network Status Sheet. If you can print out the sheet, make sure
that there are no errors in the settings that are printed on the sheet.
Step 2
Verify that the hub and the cables are all working properly. Check to see if the lamp on the hub for the port
the device is connected to is either lit or flashing on and off. If it is dead, confirm the following:
z Try connecting the device to another port to see if the lamp lights up.
z Try connecting the device to another hub.
z Try different LAN cables.
If all these failed, there is a possibility that your network interface is damaged. Consult the operation manual
for the device.
Step 3
If your network interface is running on TCP/IP, check to see if it has a valid IP address assigned. The default
IP address 192.168.192.168 initially set to the device cannot be used on the network due to the product
specifications. Choose a different IP address as your operational environment requires.
Step 4
Make sure that you have not selected Block in the Windows Security Warning window or in a similar warning
window displayed by a commercial security application. If you have, TMNet WinConfig cannot communicate
with other devices on the network. To enable communication, register this software as an exception in the
security settings for the Windows Firewall or other security applications that you are using.
Some commercial applications, even after you have followed the steps above, do not allow this software to
send data on the network. If this is the case, try turning off the blocking altogether in those applications'
settings or try quitting the applications before using TMNet WinConfig.
Note that the action written above is accompanied by risk. Make sure that turn on the blocking or restart the
security application after setting network interface.
