General network troubleshooting

If you are unable to install the device software, verify that:

All cable connections to the computer and the device are secure.

The network is operational and the network hub is turned on.

All applications, including virus protection programs, spyware protection
programs, and firewalls, are closed or disabled for computers running Windows.

Make sure the device is installed on the same subnet as the computers that
will be using the device.

If the installation program cannot discover the device, print the network
configuration page, and enter the IP address manually in the installation
program. For more information, see

Understand the network configuration page

If you are using a computer running Windows, make sure that the network ports
created in the device driver match the device IP address:

Print the device’s network configuration page.

Click Start, point to Settings, and then click Printers or Printers and Faxes.
- Or -
Click Start, click Control Panel, and then double-click Printers.

Right-click the device icon, click Properties, and then click the Ports tab.

Select the TCP/IP port for the device, and then click Configure Port.

Compare the IP address listed in the dialog box and make sure it matches the
IP address listed on the network configuration page. If the IP addresses are
different, change the IP address in the dialog box to match the address on the
network configuration page.

Click OK twice to save the settings and close the dialog boxes.

Problems connecting to a wired network

If the Link light on the network connector does not turn on, make sure that all of
the “General network troubleshooting” conditions are met.

Though it is not recommended that you assign the device with a static IP address,
you might resolve some installation problems (such as a conflict with a personal
firewall) by doing so.
