Every device on a network that uses TCP/IP must have an IP address. IP addresses are essentially unique computer
names in a numeric format, used to transfer data around a network. IP addresses allow TCP/IP to confirm requests for,
and receipt of, data by various devices on the network.
How do I locate IP addresses?
For Windows users
1
Click , or click Start and then click Run.
2 In the Start Search or Run box, type cmd.
3 Press Enter, or click OK.
4 Type ipconfig, and then press Enter.
The IP address appears as four sets of numbers separated by periods, such as 192.168.0.100.

Locating the printer IP address
•
From the printer, print a network setup page.
In the TCP/IP section, look for Address.
• View the printer settings.
From the printer control panel, navigate to:
> Setup > > Network Setup > > Wireless 802.11 b/g/n > > Network Connection Setup > > TCP/IP >
> IP Address >
How are IP addresses assigned?
An IP address may be assigned automatically by the network using DHCP. Once the printer is set up on a computer, the
computer sends all print jobs across the network to the printer using this address.
If the IP address is not automatically assigned, you will be asked during wireless setup to manually enter an address
and other network information after selecting your printer from the available list.
What is a key index?
An access point (wireless router) can be configured with as many as four WEP keys. Only one key is used on the network
at a time, however. The keys are numbered, and the number of a key is referred to as its key index. All devices on the
wireless network must be configured to use the same key index when multiple WEP keys are configured on the access
point.
Select the same key index on your printer as you are using on your access point.
