Networking
General networking
Networking overview
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 either
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 print server attached or installed that enables it to receive
and transmit radio waves.
Common home network configurations
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 different ways a network can be set up. Five common examples appear below.
Note: The printers in the following diagrams represent Lexmark printers with Lexmark internal print servers built in
or installed in them so that they can communicate over a network. Lexmark internal print servers are devices made
by Lexmark to enable Lexmark printers to be connected to wired or wireless networks.
Wired network example
•A computer, a laptop, and a printer are connected by Ethernet cables to a hub, router, or switch.
•The network is connected to the Internet through a DSL or a cable modem.
Internet
Wireless network examples
Four common wireless networks appear below:
•Scenario 1: Laptop and printer connected wirelessly with Internet
•Scenario 2: Computer, laptop, and printer connected wirelessly with Internet
•Scenario 3: Computer, laptop, and printer connected wirelessly without Internet
•Scenario 4: Laptop connected wirelessly to printer without Internet
31

Scenario 1: Laptop and printer connected wirelessly with Internet
•A computer is connected to a wireless router by an Ethernet cable.
•A laptop and a printer are connected wirelessly to the router.
•The network is connected to the Internet through a DSL or a cable modem.

32

Scenario 3: Computer, laptop, and printer connected wirelessly without Internet
•A computer, a laptop, and a printer are connected wirelessly to a wireless access point.
•The network has no connection to the Internet.
Scenario 4: Laptop connected wirelessly to printer without Internet
•A laptop is directly connected wirelessly to a printer without going through a wireless router.
•The network has no connection to the Internet.
What information do I need and where do I find it?
This printer may contain an internal wireless print server, which allows the printer to be used on a wireless network.
You need the following settings from your existing wireless network:
•The network name, also known as the SSID
•The wireless mode (the type of wireless network you are using, either infrastructure or ad hoc)
•The type of security used on the network (WEP, WPA, or WPA2)
•Any applicable security keys or passwords used with the network security encryption type
Note: You must know this information in order to properly set up the printer for use on the wireless network. To
obtain these settings, see the documentation that came with your wireless router or consult the person who set up
your wireless network.
Finding 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.
If your printer has a factory installed internal wireless print server, the MAC address is a series of letters and numbers
located on the back of your printer.
33

If you purchased the internal wireless print server separately, the MAC address appears on an adhesive label that
came with the wireless print server. Attach the adhesive label to your printer so you will be able to find the MAC
address when you need it.
UAA: XX XX XX XX XX XX
Note: A list of MAC addresses can be set on a router so that only devices with matching MAC addresses can be
allowed to operate on the network. This is called MAC filtering. If MAC filtering is enabled in your router and you
want to add a printer to your network, the MAC address of the printer must be included in the MAC filter list.
Printing a network setup page
A network setup page lists your network configuration settings.
Note: You can print a network setup page only when an internal wireless print server is installed in the printer.
To print a network setup page:
1From the control panel of the printer, press or repeatedly until Setup is highlighted.
2Press .
3Press or repeatedly until Network Setup is highlighted.
4Press .
5Press or repeatedly until Print Network Setup Page is highlighted.
6Press
A network setup page prints.

\printer.
gClick OK.
hClick Close on the Printer Ports dialog box.
iMake sure the new port is selected on the Ports tab, and then click Apply.
The new port is listed with the printer name.
jClick OK.
Finding a printer/print server located on remote subnets
The printer software CD can automatically find the printers that are located on the same network as the computer.
If the printer and print server are located on another network (called a subnet), you must manually enter an IP address
during printer software installation.
Wireless networking
Finding IP addresses
An IP address is a unique number used by devices on an IP network to locate and communicate with each other.
Devices on an IP network can only communicate with each other 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.
How to locate a printer IP address
You can locate the printer IP address by printing out the printer network setup page. For more information, see
“Printing a network setup page” on page 34.
How to locate a computer IP address
1Do one of the following:
•In Windows Vista, click All Programs Accessories Command Prompt.
•In Windows XP, click Start Programs or All Programs Accessories Command Prompt.
2Type ipconfig.
35

3Press Enter.
The IP address appears as four sets of numbers separated by periods, such as 192.168.0.100.
Assigning an IP address
An IP address may be assigned by the network using DHCP. The print object, created at the end of the installation,
sends all print jobs across the network to the printer using this address.
Many networks have the ability to automatically assign an IP address. Auto-IP is the ability for individual devices to
assign themselves a unique IP address. Most networks use DHCP to assign addresses.
During the Direct IP printing installation of printer software, the IP address is visible in the printer list only as it is
being assigned. The print object that is created in the Printers folder of the operating system will reference the MAC
address of the printer in the port name.
If the IP address is not automatically assigned, you can try manually entering an address after selecting your printer
from the available list.
Configure IP address
If you have lost communication with the printer over a network, select Use DHCP to reestablish communication with
the printer.
You must assign an IP address in any of the following situations:
•You manually assigned IP addresses for the other network devices.
•You want to assign a specific IP address.
•You move the printer to a remote subnet.
•The printer is listed as Unconfigured in the Configuration Utility.
Contact your system support person for more information.
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 even 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.
Installing the printer on a network
Follow the instructions for the networking method you want to use. Make sure the selected network is set up and
working properly, and that all relevant devices are turned on. For more information on your specific network, see
your network documentation or consult the person who set up the network.

Types of wireless networks
Networks can operate in one of two modes: infrastructure or ad hoc. Lexmark recommends setting up a network in
infrastructure mode using the installation CD that came with the printer.
A wireless network where each device communicates with others through a wireless access point (wireless router)
is set up in infrastructure mode. All devices must have valid IP addresses and share the same SSID and channel.
In addition, they must share the same SSID and channel as the wireless access point (wireless router).
A simple type of wireless network is one where a PC with a wireless adapter communicates directly with a printer
equipped for wireless networking. This mode of communication is called ad hoc. A device in this type of network
must have a valid IP address and be set to ad hoc mode. The wireless print server must also be configured with the
same SSID and channel.
Infrastructure Ad hoc

Tips for using network adapters
•Make sure the adapter connections are secure.
•Make sure the computer is turned on.
•Make sure you entered the correct IP address.

Advanced wireless setup
Creating an ad hoc wireless network using Windows
The recommended way to set up your wireless network is to use a wireless access point (wireless router). A network
set up this way is called an infrastructure network. If you have an infrastructure network in your home, you should
configure your printer for use on that network.
If you don't have a wireless access point (wireless router) or would like to set up a standalone network between your
printer and a computer with a wireless network adapter, you can set up an ad hoc network.
For Windows Vista users
1Click Control Panel Network and Internet.
2Under Network and Sharing Center, click Connect to a Network.
3In the Connect to a Network dialog, click Set up a wireless ad-hoc (computer-to-computer) network, and
then click Next.
4Follow the instructions in the “Set up a wireless ad hoc network” wizard. As part of the setup:
aCreate a network name or SSID for the network between the computer and your printer.
bWrite the name of your network in the space provided. Be sure to use the exact spelling and capitalization.
cGo to the Security Type drop-down, choose WEP, and create a security key (or password).
Note: WEP passwords must be either 5 or 13 characters.
dWrite the password for your network in the space provided. Be sure to use the exact spelling and
capitalization.
Windows Vista will enable the ad hoc network for you. It will appear in the “Connect to a network” dialog under
available networks, indicating that the computer is configured for the ad hoc network.
5Close the Control Panel and any remaining windows.
6Insert the printer CD into the computer and follow the direction for wireless installation.

These are possible solutions. Try one or more of the following:
Make sure the access point is on
Check the access point and, if necessary, turn it on.
Move your wireless access point (wireless router) to minimize interference
There may be temporary interference from other devices such as microwave ovens or other appliances, cordless
phones, baby monitors, and security system cameras. Make sure your wireless access point (wireless router) is not
positioned too closely to these devices.
Try adjusting external antennas
Generally, antennas work best if they are pointing straight up. You may find, however, that reception improves if you
experiment with different angles for your printer and/or wireless access point (wireless router) antennas.

Move your computer and/or printer
Move the computer and/or printer closer to the wireless access point (wireless router). Although the possible distance
between devices in 802.11b or 802.11g networks is 300 feet, the effective range for optimal performance is generally
100–150 feet.
You can find the signal strength of the network on the network setup page. For information on how to print a setup
page, see “Printing a network setup page” on page 34.
Check security keys
Make sure security keys are correct. For more information, see “Check your security keys” on page 106.
Check MAC address
If your network uses MAC address filtering, provide the MAC address for the printer to your network. If you need
help finding the MAC address, see “Finding the MAC address” on page 33.
Ping the wireless access point (wireless router) to make sure the network is working
1If you do not already know it, find the IP address of the access point.

cPress Enter.
•The “Default Gateway” entry is typically the wireless access point (wireless router).
•The IP address appears as four sets of numbers separated by periods, such as 192.168.0.100. Your IP
address might also start with the numbers 10 or 169. This is determined by your operating system or
wireless network software.
2Ping the wireless access point (wireless router).
aClick:
•In Windows Vista: All Programs Accessories Command Prompt.
•In Windows XP and earlier: Start Programs or All Programs Accessories Command
Prompt.

not include the word “wireless” in its name.
cRight-click the connection, and then click Repair.
Run the wireless setup again
If your wireless settings have changed, you must run the printer wireless setup again. Some reasons your settings
may have changed include your having manually changed your WEP or WPA keys, channel, or other network
settings; or the wireless access point (wireless router) having been reset to factory defaults.
Notes:
•If you change network settings, change them on all the network devices before changing them for the wireless
access point (wireless router).
•If you have already changed the wireless network settings on your wireless access point (wireless router), you
must change the settings on all the other network devices before you can see them on the network.
1Click:
•In Windows Vista: .
•In Windows XP and earlier: Start.
2Click Programs or All Programs Lexmark 4800 Series.
3Click Wireless Setup.
Note: You may be prompted to connect the printer to the computer again using the installation cable as part of
the setup process.
4Follow the instructions on the computer screen.

These are possible solutions. Try one or more of the following:
Check cable
Make sure the installation cable is not connected to the printer.
Configure the optional internal wireless print server
Note: This solution does not apply to printers that have a pre-installed internal wireless print server.
If you purchased the optional internal wireless print server after your printer was already set up, see “Configuring
the optional internal wireless print server” in the “Setting up the printer” chapter.
Check network name
Make sure your network does not have the same name as another network near you. For example, if you and your
neighbor both use a manufacturer's default network name, your printer could be connecting to your neighbor's
network.
If you are not using a unique network name, consult the documentation for your wireless access point (wireless
router) to learn how to set a network name.
If you set a new network name, you must reset the printer and computer SSID to the same network name.
For more information, see “Checking your network name” in the “Wireless troubleshooting” section.
