❏ IP Address—A unique identifier for each device on a TCP/IP network.
❏ Subnet Mask—A filter used to determine what subnet an IP address belongs to.
❏ Gateway—A node on a network that serves as an entrance to another network.
Since the IP address for each PC and printer on your network must be unique, you usually need to
modify this preset address so it doesn't conflict with any other IP address or your network or any
attached network. You can do this in one of two ways. Each is explained in detail in the following
sections.
❏ Using DHCP
❏ Setting the address manually
Using DHCP
If your network supports DHCP (Dynamic Host Configuration Protocol), the printer's IP address will
be automatically assigned by the DHCP server when you turn on the printer. (Refer to "Network
Printing" on page 52 for a description of DHCP.)
Note:
If your printer is not automatically assigned an IP address, verify that DHCP is enabled on the printer
(PRINT MENU - CONFIGURATION PG). If it is not enabled, you can enable it in the INTERFACE MENU -
ETHERNET - TCP/IP - DHCP menu.
1. Connect your printer to the network.
When using an Ethernet cable, plug the RJ45 connector into the Ethernet interface port of the
printer.
2. Turn on your PC and printer.
3. When the printer's message window displays READY, press the Menu/Select key.
4. Select PRINT MENU.
5. Press the Menu/Select key twice to print the configuration page and verify the IP address settings.
6. Install the printer driver and utilities.
Note:
If the printer cannot be connected to a DHCP server, an IP address within the range between
169.254.0.0 and 169.254.255.255 is automatically set.
