							Network Connection2-3 Making the Connection
Ethernet Interface
An RJ45 connector can be used as the Ethernet interface for this machine.
When connecting your machine to an Ethernet network, the tasks you per-
form depend on how you plan to set the machine’s IP (Internet Protocol) 
address.
„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 machine 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 sec-
tions.
„Using DHCP
„Setting the address manually
Using DHCP
If your network supports DHCP (Dynamic Host Configuration Protocol), the 
machine’s IP address will be automatically assigned by the DHCP server 
when you turn on the machine. (Refer to “Network Printing” on page 2-6 for a 
description of DHCP.)
If the IP address of the machine is not set automatically, check if the 
machine has been set to allow DHCP to be used (
REPORT/STATUS 
— REPORT — CONFIGURATION PAGE). If the machine has been 
set so that DHCP cannot be used, select 
AUTO in the UTILITY - 
ADMIN. MANAGEMENT - NETWORK SETTING - IP ADDR. 
SETTING
 menu, and ENABLE in the UTILITY - ADMIN. MAN-
AGEMENT - NETWORK SETTING - DHCP
 menu.
1Connect your machine to the network. 
When using an Ethernet cable, plug the RJ45 connector into the Ethernet 
interface port of the machine.
2Turn on your PC and machine.
3After the machine’s message window is initialized, install the printer driver.

Setting the Address Manually
You may also manually change the machine’s IP address, subnet mask, and 
gateway by using the following instructions. (See chapter 1, “Understanding 
the Network Setting Menu,” for more information.) 
When the IP address is changed, add a new port or reinstall the 
printer driver.
CAUTION
You should always notify your network’s administrator before changing 
the machine’s IP address.
1Turn on your PC and machine.

Bonjour
Macintosh network technology for automatically detecting devices connected 
to the network and for specifying settings. Previously called “Rendezvous”, 
the name was changed to “Bonjour” starting with Mac OS X v10.4.
BOOTP
BOOTP (Bootstrap Protocol) is an Internet protocol that enables a diskless 
workstation to discover (1) its own IP address, (2) the IP address of a BOOTP 
server on the network, and (3) a file that can be loaded into memory to boot 
the workstation. This enables the workstation to boot without requiring a hard 
or floppy disk drive.

DHCP
DHCP (Dynamic Host Configuration Protocol) is a protocol for assigning 
dynamic IP addresses to devices on a network. With dynamic addressing, a 
device can have a different IP address every time it connects to the network. 
In some systems, the device’s IP address can even change while it is still 
connected. DHCP also supports a mix of static and dynamic IP addresses. 
Dynamic addressing simplifies network administration because the software 
keeps track of IP addresses rather than requiring an administrator to manage 
the task. This means that a new computer can be added to a network without 
the hassle of manually assigning it a unique IP address. 
DNS
Abbreviation for Domain Name System. A system that acquires the sup-
ported IP addresses from host names in a network environment. DNS allows 
the user to access other computers over a network by specifying host names, 
instead of difficult to memorize and understand IP addresses.
FTP
Abbreviation for File Transfer Protocol. A protocol for transferring files over 
the Internet or an intranet on the TCP/IP network.
HTTP
HTTP (HyperText Transfer Protocol) is the underlying protocol used by the 
World Wide Web. It defines how messages are formatted and transmitted, 
and what actions web servers and browsers should take in response to vari-
ous commands. For example, when you enter a URL in your browser, this 
actually sends an HTTP command to the Web server directing it to fetch and 
transmit the requested web page. 
IPP
IPP (Internet Printing Protocol) is a protocol for end users’ most common 
printing situations over the Internet. It allows users to find out about a printer’s 
capabilities, submit print jobs to a printer, determine the status of the printer 
or print job, and cancel a previously submitted print job.
For more information on using IPP, See “Printing via IPP (Internet Printing 
Protocol)” on page 2-11.

LDAP
On a TCP/ IP network, such as the Internet or an intranet, LDAP (Lightweight 
Directory Access Protocol) is a protocol that is used to access a database for 
managing environment information and the e-mail addresses of network 
users.
LPD/LPR
LPD/LPR (Line Printer Daemon/Line Printer Remote) is a platform-
independent printing protocol that runs over TCP/IP. Originally implemented 
for BSD UNIX, its use has spread into the desktop world and is now an 
industry standard. 
POP Before SMTP
A user authentication method for sending E-mail messages. First, the recep-
tion operation is performed and the user is authenticated by the POP server. 
Then, IP addresses where the user was successfully authenticated by the 
POP server are permitted to use the SMTP server. This method prevents 
third parties without permission to use the mail server from sending mail mes-
sages.
Port 9100
When printing through a network, TCP/IP port number 9100 can be used to 
send raw data.
SLP
Traditionally, in order to locate services on the network, users had to supply 
the host name or network address of the machine providing the desired ser-
vice. This has created many administrative problems. 
However, SLP (Service Location Protocol) simplifies the discovery and use of 
network resources such as printers by automating a number of network ser-
vices. It provides a framework that allows networking applications to discover 
the existence, location, and configuration of networked services.
With SLP users no longer need to know the names of network hosts. Instead, 
they need to know only the description of the service they are interested in. 
Based on this description, SLP is able to return the URL of the desired 
service.

Unicast, Multicast, and Broadcast
SLP is a unicast and a multicast protocol. This means that messages can be 
sent to one agent at a time (unicast) or to all agents (that are listening) at the 
same time (multicast). However, a multicast is not a broadcast. In theory, 
broadcast messages are “heard” by every node on the network. Multicast 
differs from broadcast because multicast messages are only “heard” by the 
nodes on the network that have “joined the multicast group.” 
For obvious reasons network routers filter almost all broadcast traffic. This 
means that broadcasts that are generated on one subnet will not be “routed” 
or forwarded to any of the other subnets connected to the router (from the 
router’s perspective, a subnet is all machines connected to one of its ports). 
Multicasts, on the other hand, are forwarded by routers. Multicast traffic from 
a given group is forwarded by routers to all subnets that have at least one 
machine that is interested in receiving the multicast for that group. 
SMB
SMB (Server Message Block) is a protocol for sharing network resources, 
such as files and printers, in a Windows environment. If the Samba server 
software is used on Linux or UNIX, services using SMB can be shared.
SMTP
SMTP (Simple Mail Transfer Protocol) is a protocol for sending E-mail.
This protocol was originally used to send E-mail between servers; however, 
currently it is also used by client E-mail software that uses POP to send 
E-mail to servers.
SMTP Authentication
Specification that adds user authentication functions to SMTP, which is used 
for sending E-mail.
When sending E-mail, authentication of the user is performed by the SMTP 
server, and the E-mail message is permitted to be sent only if authentication 
was successful.
SNMP
SNMP (Simple Network Management Protocol) is actually a set of protocols 
for managing complex networks. SNMP works by sending messages to differ-
ent parts of a network. SNMP-compliant devices, called agents, store data 
about themselves in Management Information Bases (MIBs) and return this 
data to the SNMP requesters.

TCP/IP
Most networks combine TCP (Transmission Control Protocol) with the 
lower-level protocol IP (Internet Protocol). TCP establishes a virtual connec-
tion between two host systems and guarantees the delivery of data between 
them while IP specifies the format and addressing of this data sent between 
these two host systems.
