Limitation of liability 

Your sole remedy under this Statement of 
Limited Warranty is set forth in this section. 
For any claim concerning performance or 
nonperformance of Lexmark or a 
Remarketer for this product under this 
Statement of Limited Warranty, you may 
recover actual damages up to the limit set

Lexmark's liability for actual damages from 
any cause whatsoever will be limited to the 
greater of 1) $5,000 or 2) the amount you 
paid for the product that caused the 
damages. This limitation of liability will not 
apply to claims by you for bodily injury or 
damage to real property or tangible 
personal property for which Lexmark is 
legally liable. In no event will Lexmark be 
liable for any lost profits, lost savings,

possibility of such damages. Lexmark is 
not liable for any claim by you based on a 
third party claim.

Such developer is an intended beneficiary 
of this limitation. 
Additional rights 

Some states do not allow limitations on 
how long an implied warranty lasts, or do 
not allow the exclusion or limitation of 
incidental or consequential damages. If 
such laws apply, the limitations or 
exclusions contained in this statement may 
not apply to you.

This warranty gives you specific legal

Setting up your wireless print server

Setup overview

The setup process consists of three parts: physically connecting the print server to your printer using 
the provided USB cable, configuring your wireless print server, and installing your printer on the 
network. After the print server ha been attached to the printer, the configuration segment involves 
using Zero configuration networking to connect to the print server over the computer to computer 
(Ad-Hoc) wireless network and changing the print server wireless network settings. The installation 
segment involves connecting the print server to the printer that you want to install and running the 
printer drivers or printer software CD to install it as a network printer. 

The setup process accommodates networks that use either Infrastructure mode (in which the 
network structure is based on a series of wireless routers or base stations) or Ad-Hoc mode (in 
which wireless devices communicate with each other directly without using a wireless router).

Before setting up your wireless print server, make sure your printer has been set up correctly

The toner or print cartridges are installed correctly.

Paper has been loaded into the printer.

Your printer is turned on and ready to be installed.

For help setting up your printer, refer to your printer documentation.

My wireless print server was unable to join the network

Between 8 and 63 ASCII characters

My wireless print server was unable to join the network

There are many factors that can prevent the print server from joining the network. Here are some of 
the most common troubleshooting options: 

Verify that the print server settings match those used by your wireless network. 

Verify that the print server is within range of the network.

If your network uses MAC address filtering, provide the MAC address for the print server to 
your network. The MAC address can be found on the bottom of the print server. 

The print server was configured correctly, but cannot be found
on the network

Verify that the print server has power and that the power indicator light is on.

Verify that the print server is within range of the wireless network.

Verify that the print server is located away from other electronic devices that may interfere 
with the wireless signal. 

Verify that your wireless network is using a unique network name (SSID). If not, it is possible 
that the print server is communicating over a different, nearby network that uses the same 
network name.

Verify that the print server has a valid IP address on the network. 

No printer was found attached to the print server

Verify that the USB cable is properly connected to both the printer and the print server.

Verify that the printer has power. 

Verify that the printer was set up correctly. 

Verify that the print server has power and is available on your network.

Make sure the network is operating properly.

Refer to your network documentation, or contact the person who set up your network if you 
are not sure that your network is operating correctly.

Make sure the printer driver is installed on the computer from which you are sending the print 
job.

Note: You must install the printer driver on each computer that uses the network printer.

Make sure the correct printer port is selected. 

Restart the computer.

Uninstall and then reinstall the printer software.

If the printer still does not print, refer to your printer documentation for help.

Make sure there is not a problem with the printer itself.

1

Disconnect the printer from the printer adapter.

2

Attach the printer directly to your computer with a USB cable.

3

Open a text document, and choose File

Print

4

Select the attached printer in the Printer pop-up window, and click Print

If you are able to print when the printer is directly attached, there may be a problem with your 
network. Refer to your network documentation, or contact your network administrator.

Glossary

Ad-Hoc network.

A stand-alone or peer-to-peer network in which wireless devices communicate directly 

with one another without using a wireless access point or base station. 

AirPort.

The Apple name for 802.11b and 802.11g wireless networking standards.

ASCII.

A standard character set consisting of 96 uppercase and lowercase letters, plus 32 nonprinting control 

characters. 

BSS Type.

Basic Service Set, the type of wireless network that you are using. The BSS type can be one of 

the following:

• Infrastructure network 
• Ad-Hoc network

Channel number.

A number associated with the radio frequency at which an 802.11 device operates. The 

channel numbers available vary by geographical region. 

Data Encryption mode.

The security protocol that is used to protect data that is transferred accross your 

wireless network and provide network authentication. You can use one of the following protocols for data 
encryption:

• None
• Shared—WEP (Wired Equivalency Protocol)
• WPA-Personal (TKIP:PSK)—WPA (Wi-Fi Protected Access) in PSK (Pre-Shared Key) mode

DHCP.

Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to devices on a 

network. With dynamic addressing, a device can automatically request an IP address every time it connects to 
the network. This means that a new device can be added to a network without having to manually assign a 
unique IP address. 

Hexadecimal.

A numbering system that is used as a representation of binary numbers using a base of 16 

digits. 

Infrastructure network.

A network in which your wireless devices communicate through a central wireless 

access point or base station. An infrastructure network can contain multiple wireless access points.

IP address. A number that identifies each device connected to the network. For example, 
192.168.0.1.

MAC address. A 12-character identifier that is unique for each network hardware device. For 
example, 0002001008e8.

Network authentication type.

The data encryption mode that is used on your network to prevent 

unauthorized users or devices from connecting to or accessing your wireless network. You can use one of the 
following protocols for network authentication:

• None
• WEP
• WPA (Infrastructure mode networks only)

network-capable printer.

A printing device that does not need to be locally attached to a computer. 

printer port. Windows terminology for a physical or logical connection to a printer. For example: 

• LPT1 indicates the printer is attached to a physical parallel port with a parallel cable.
• USB001 indicates the printer is attached to a physical USB port with a USB cable.
• Print_Server_E320_0020000035D0 indicates a logical connection to the printer across your network.

valid keys are between 8 and 63 characters long. WPA authentication is not supported for Ad-Hoc 
configurations.

• For WEP keys, if using Hex characters, valid keys are either 10 or 26 characters long; if using ASCII, valid 

keys are either 5 or 13 characters long.

subnet.

A portion of a network that shares a common address component. On TCP/IP networks, subnets are 

defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses 
that start with 192.168.0. would typically be part of the same subnet.

SSID.

Service Set ID, also known as Network name, is a unique identifier used to distinguish one wireless 

network from another. Wireless devices must use the same SSID to communicate. SSIDs are up to 32 
characters long, and are case-sensitive.
