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

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.

Internet

Scenario 2: Computer, laptop, and printer connected wirelessly with Internet

•A computer, a laptop, and a printer are connected wirelessly to a wireless router.

•The network is connected to the Internet through a DSL or a cable modem.

Internet

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.

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.

Sharing a printer in a Windows environment

1Prepare the computers to share the printer.

aMake all computers printing to the printer accessible through Network Neighborhood by enabling File and

Print Sharing. See the Windows documentation for detailed instructions.

bInstall the printer software on all computers that will print to the printer.

2Identify the printer.

On the computer that is attached to the printer:

aClick Start Settings Printers or Printers and Faxes.

bRight-click the Lexmark 4800 Series icon.

cClick Sharing.

dClick Shared As, and give the printer a distinctive name.

eClick OK.

3Locate the printer from the remote computer.

Note: The remote computer is the one that is not attached to the printer.

Windows 2000 or Windows XP users only:

aClick Start Settings Printers and Faxes.

bRight-click the Lexmark 4800 Series icon.

cClick Properties.

dClick the Ports tab, and then click Add Port....

eSelect Local Port, and then click New Port....

fEnter the Universal Naming Convention (UNC) Port name which consists of the server name and the

distinctive printer name that was specified in step 2 on page 34. The name should be in the form \\server

\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.

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.

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.

7When the available networks are displayed, provide the network name and the security information you created

in step 4. The installer will configure the printer for use with the computer.
