							Where do I find my WEP key or WPA passphrase?
To find the WEP key or WPA passphrase for the wireless network, view the security settings on the access point or
wireless router. Most access points have a Web page that can be accessed using a Web browser.
You can also check the manual that came with your access point or router. If your access point or router is using the
default settings, you can find the information in the manual. If someone else set up your network for you, that person
or company may have included the information in the manual.
If you do not know how to access the Web page, or if you do not have administrator access to the wireless access point
on your network, and are unable to locate the information in the manual, contact your system support person.
What is an SSID?
A Service Set Identifier (SSID) is the name that identifies a wireless network. All devices on the network must know the
SSID of the wireless network or they will not be able to communicate with each other. Usually, the wireless network
broadcasts the SSID to allow wireless devices in the area to connect to it. Sometimes, the SSID is not broadcast for
security reasons.
If the SSID of your wireless network is not broadcast, it cannot be detected automatically and will not show up in the
list of available wireless networks. You must enter the network information manually in this situation.
An SSID can contain up to 32 alphanumeric characters.
Where do I find my SSID?
You can find the SSID for the wireless network by viewing the settings on the access point or wireless router. Most
access points have a built-in Web server that can be accessed using a Web browser.
Many network adapters provide a software application that allows you to view the wireless settings of your computer,
including your SSID. Check your computer to see if a program was installed with your network adapter.
If you are unable to locate your SSID using either of these methods, contact your system support person.
What is a network?
A network is a collection of devices such as computers, printers, Ethernet hubs, wireless access points, and routers
connected together for communication through cables or through a wireless connection. A network can be wired,
wireless, or designed to have both wired and wireless devices.
Devices on a wired network use cables to communicate with each other.
Devices on a wireless network use radio waves instead of cables to communicate with each other. For a device to be
able to communicate wirelessly, it must have a wireless network adapter attached or installed that lets it receive and
transmit radio waves.

							How do I find out what type of security my network is using?
You must know the WEP key or WPA passphrase and the type of security (WEP, WPA, or WPA2) used on the wireless
network. To obtain this information, see the documentation that came with your wireless access point (wireless router),
see the Web page associated with the wireless access point, or consult your system support person.
Note: The WEP key or WPA passphrase is not the same as the password for the wireless access point. The password
allows you to access the wireless access point settings. The WEP key or WPA passphrase allows printers and computers
to join your wireless network.
How are home networks configured?
For desktop computers, laptops, and printers to communicate with each other over a network, they must be connected
by cables and/or have wireless network adapters built in or installed in them.
There are many different ways a network can be set up. Four common examples appear below.
Note: The printers in the following diagrams represent printers with internal print servers built into them so that they
can communicate over a network.
Wireless network examples
Scenario 1: Mixed wired and wireless connections on a network with Internet access

All computers and printers connect to the network through a router with Ethernet and wireless capabilities.
Some computers and printers connect wirelessly to the router; others connect over a wired connection.
The network is connected to the Internet through a DSL or cable modem.

							Scenario 2: Wireless network with Internet access

All computers and printers connect to the network using a wireless access point or wireless router.
The wireless access point connects the network to the Internet through a DSL or cable modem.
Internet
Scenario 3: Wireless network with no Internet access

Computers and printers connect to the network using a wireless access point.
The network has no connection to the Internet.
Scenario 4: Computer connected wirelessly to a printer without Internet access

A computer is directly connected to a printer without going through a wireless router.
This configuration is referred to as an ad hoc network.
The network has no connection to the Internet.
Note: Most computers can connect to only one wireless network at a time. If you access the Internet over a wireless
connection, you will lose Internet access if you are connected to an ad hoc network.
Why do I need an installation cable?
When setting up the printer on your wireless network, the printer will need to temporarily connect to a computer using
the installation cable. This temporary connection is used to set up the wireless settings of the printer.

							The installation cable connects to a rectangular USB port on the installing computer and the square USB port on the
printer.
How do I attach the installation cable?
The installation cable attaches to a USB port on the computer and to the square connector on the back of the printer.
This connection allows you to configure the printer for a networked or locally attached installation.
1Attach the large, rectangular connector to any USB port on your computer. USB ports may be on the front or the
back of the computer, and may be horizontal or vertical.
2Attach the small, square connector to the printer.
3Continue following the on-screen instructions.
How are infrastructure and ad hoc networks different?
Wireless networks can operate in one of two modes: infrastructure or ad hoc.
In infrastructure mode, all devices on a wireless network communicate with each other through a wireless router
(wireless access point). Devices on the wireless network must have valid IP addresses for the current network and share
the same SSID and channel as the wireless access point.
In ad hoc mode, a computer with a wireless network adapter communicates directly with a printer equipped with a
wireless print server. The computer must have a valid IP address for the current network and be set to ad hoc mode.
The wireless print server must be configured to use the same SSID and channel that the computer is using.

Finding the signal strength
Wireless devices have built-in antennas that transmit and receive radio signals. The signal strength listed on the printer
network setup page indicates how strongly a transmitted signal is being received. Many factors can affect the signal
strength. One factor is interference from other wireless devices or other devices such as microwave ovens. Another
factor is distance. The farther two wireless devices are from each other, the more likely it is that the communication
signal will be weaker.
The strength of the signal received by your computer can also affect the connectivity of the printer with the network
during configuration. When you installed the wireless adapter in your computer, the adapter software probably placed
an icon in your system tray. Try double-clicking this icon, and it will tell you how strongly the computer is receiving the
wireless signal from the network.
To improve signal quality, remove sources of interference and/or move wireless devices closer to the wireless access
point (wireless router).

							How can I improve wireless signal strength?
A common reason wireless printers fail to communicate over a network is poor wireless signal quality. If the signal is
too weak, too distorted, or blocked by an object, it cannot carry information between the access point and the printer.
To determine if the printer is receiving a strong signal from the access point, print a network setup page. The Quality
field indicates the relative strength of the wireless signal the printer is receiving. Drops in signal strength can be
intermittent, however, and although the signal quality appears high, it may drop during certain conditions.
If you think signal strength is a problem between your access point and the printer, try one or more of the following:
Notes:
The solutions below are for infrastructure networks. If you are using an ad hoc network, adjust the computer when
the solution suggests adjusting the access point.
Ad hoc networks have a much shorter range than infrastructure networks. Try moving the printer closer to the
computer if they seem to have trouble communicating.
MOVE THE PRINTER CLOSER TO THE WIRELESS ACCESS POINT/WIRELESS ROUTER
If the printer is too far away from the access point, it will not be able to communicate with other devices on the
network. For most indoor wireless networks, the maximum distance between the access point and the printer is
approximately 100 feet (30 meters). This distance could be longer or shorter, depending upon the layout of the
network and the limitations of the access point.
REMOVE OBSTACLES BETWEEN THE ACCESS POINT AND THE PRINTER
The wireless signal from your access point will pass through most objects. Most walls, floors, furniture and other
objects will not block the wireless signal. However, there are materials that are too dense for the signal to pass
through. Objects containing metal and concrete can block the signal. Arrange your printer and access point so that
the signal is not blocked by such objects.
REMOVE SOURCES OF INTERFERENCE
Other types of radio frequencies can cause problems with the wireless signal on your network. These sources of
interference can cause printing issues that seem to come and go. Turn off potential sources of interference where
possible. Avoid using microwaves and cordless phones when printing over your wireless network.
If another wireless network is operating in the vicinity, change the wireless channel on the access point.
Do not place your access point on a printer or other electronic device. Such devices can also interfere with the wireless
signal.
ARRANGE THE NETWORK TO REDUCE SIGNAL ABSORPTION
Even when the wireless signal is able to pass through an object, it is slightly weakened. If it passes through too many
objects, it can be significantly weakened. All objects absorb part of the wireless signal when it passes through them,
and certain types of objects absorb enough to cause communications problems. Place your access point as high in
the room as possible to avoid signal absorption.

							How can I make sure my computer and printer are connected to the same wireless
network?
If the printer is not on the same wireless network as the computer, then you will not be able to print wirelessly. The
SSID of the printer must match the SSID of the computer, if the computer is already connected to the wireless network.
For Windows users
1Obtain the SSID of the network that the computer is connected to:
aType the IP address of your access point (wireless router) in the address field of your Web browser.
If you do not know the IP address of the access point:
1Click , or click Start and then click Run.
2In the Start Search or Run box, type cmd.
3Press Enter, or click OK.
4Type ipconfig, and then press Enter. Check the Wireless Network Connection section:
The “Default Gateway” entry is typically the access point.
The IP address appears as four sets of numbers separated by periods, such as 192.168.2.134.
bType the user name and password of the router when prompted.
cClick OK.
dIn the Wireless settings section, look for the SSID.
eWrite down the SSID.
Note: Make sure you copy it exactly, including any capital letters.
2Obtain the SSID of the network that the printer is connected to:
aFrom the printer, print a network setup page.
bIn the Wireless section, look for SSID.
3Compare the SSID of the computer and SSID of the printer.
If the SSIDs are the same, then the computer and the printer are connected to the same wireless network.
If the SSIDs are not the same, then run the utility again to set up the printer on the wireless network used by the
computer.

Can I use my printer on a USB and a network connection at the same time?
Yes, the printer supports a simultaneous USB and network connection. The printer can be configured in the following
ways:
Locally attached (connected to a computer using a USB cable)
Wireless network
Wireless network and locally attached simultaneously
What is a MAC address?
A Media Access Control (MAC) address is a 48-bit identifier associated with the hardware of network equipment. The
MAC address may also be called the physical address because it is connected to the hardware of a device instead of its
software. The MAC address is displayed as a hexadecimal number in this format: 01-23-45-67-89-AB.
Every device capable of communicating on a network has a MAC address. Network printers, computers, and routers,
whether Ethernet or wireless, all have MAC addresses.
While it is possible to change the MAC address of a network device, it is not common practice to do so. For this reason,
MAC addresses are considered permanent. IP addresses are easily changed, so MAC addresses are a more reliable
method of identifying a specific device on a network.
Networking

							Routers with security capabilities may allow filtering of MAC addresses on networks. This allows a managed list of
devices to access the network, identified by their MAC addresses. MAC address filtering can help prevent access on
the network from unwanted devices, such as from intruders on a wireless network. MAC address filtering can also
prevent legitimate access if you forget to add a new device to the routers list of allowed addresses. If your network
uses MAC address filtering, be sure to add the MAC address of the printer to the list of allowed devices.
How do I find the MAC address?
Most network equipment has a unique hardware identification number to distinguish it from other devices on the
network. This is called the Media Access Control (MAC) address.
When installing the printer on a network, make sure you select the printer with the correct MAC address.
The MAC address label is located inside the printer.
MA
C:
XX   XX   XX   XX   XX   XX
The MAC address of the internal print server is a series of letters and numbers. Other devices sometimes use a type of
MAC address called Universally Administered Address (UAA).
MAC: XX   XX   XX   XX   XX   XXUAA: XX   XX   XX   XX   XX   XX
Note: A list of MAC addresses can be set on an access point (router) so that only devices with matching MAC addresses
are allowed to operate on the network. This is called MAC filtering. If MAC filtering is enabled in your access point and
you want to add a printer to your network, then the MAC address of the printer must be included in the MAC filter list.
What is an IP address?
An IP address is a unique number used by devices (such as a wireless printer, computer, or wireless access point) on
an IP network to locate and communicate with each other. Devices on an IP network can communicate with each other
only if they have unique and valid IP addresses. A unique IP address means no two devices on the same network have
the same IP address.
An IP address is a group of four numbers separated by periods. An example of an IP address is 192.168.100.110.

							What is TCP/IP?
Networks are able to function because computers, printers, and other devices are able to send data to each other,
either through cables or by using wireless signals. This transfer of data is made possible by sets of data transmission
rules called protocols. A protocol can be thought of as a language, and like a language, it has rules allowing participants
to communicate with each other.
Different types of networks use different protocols, but Transmission Control Protocol/Internet Protocol ( TC P/I P)  is  the
most popular. TCP/IP is used to send data over the Internet as well as over most corporate and home networks.
Because computers do not understand words and instead rely upon numbers for communication, TCP/IP requires that
every device on a network using TCP/IP to communicate 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
1Click , or click Start and then click Run.
2In the Start Search or Run box, type cmd.
3Press Enter, or click OK.
The Command Prompt window opens.
4Type ipconfig, and then press Enter.
The IP address appears as four sets of numbers separated by periods, such as 192.168.0.100.
For Macintosh users
1From the Apple menu, choose About This Mac.
2Click More Info.
3From the Contents pane, choose Network.
4If you are connected over a wireless network, choose AirPort from the Active Services list.
How to locate a printer IP address
You can locate the printer IP address by viewing the printer network setup page.
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.
