Using DHCP
You can use the printer in a DHCP environment. You can also register the printer
NetBIOS name on a WINS server when it is running.
Note the following points when an Ethernet interface is simultaneously installed.
❖ When static IPv4 addresses are set for each interface
• IPv4 address: When set at the same value, the Ethernet interface is preferred.
• Subnet mask: When a value overlaps, the Ethernet interface is preferred.
• Gateway address: The value set is used. For the gateway address, set the
gateway address located in the subnetwork set by the interface. If the value
is outside the subnet range set by the interface, it operates as “0.0.0.0”.
❖ When obtaining addresses from the DHCP server
• IP Address, Subnet Mask: you can configure addresses assigned by a
DHCP server. If IPv4 addresses overlap or the same subnet IP addresses
are selected, the effective value is assigned only to the prioritized interface.
Ethernet has default interface priority.
• AutoNet: A temporary IPv4 address starting with 169.254 and not used on
the network, is assigned to the prioritized interface.
• Gateway Address, DNS Server Address, and Domain Name: You can con-
figure the addresses assigned by DHCP to the prioritized interface.
If the gateway address is beyond the range of the subnet selected for the
interface, the printer operates using "0.0.0.0".
Ethernet has default interface priority.
❖ When there are static IPv4 addresses and addresses assigned by DHCP
• IPv4 Address and subnet mask: if a static IPv4 address is the same as an ad-
dress assigned by DHCP, or the static subnet mask address and the subnet
mask address assigned by DHCP overlap, the printer uses the static IPv4 ad-
dress in terface. The interface with the DHCP setting is set by default.
• Gateway Address: operates using the address entered manually.
If a static address is not selected, or is set to 0.0.0.0, the interface using the
address assigned by DHCP is used.
Note
❒ NetBIOS name on a WINS server must be configured for the WINS server.
❒ Supported DHCP servers are: Windows2000 Server, Windows
Server2003, Windows NT4.0, NetWare server, and the standard DHCP
server of UNIX.
❒ If you do not use the WINS server, reserve the printer's IP address in the
DHCP server so the same IPv4 address is assigned every time.
❒ To use the WINS server, change the WINS server setting to “active” us-
ing the control panel.
❒ Using the WINS server, you can configure the host name via the remote
network printer port.
❒ DHCP relay-agent is not supported. If you use DHCP relay-agent on a network
via ISDN, it will result in increased line charges. This is because your computer
connects to the ISDN line whenever a packet is transferred from the printer.
❒ If there is more than one DHCP server, use the same setting for all servers.
The printer operates using data from the DHCP server that responds first.
