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.
1 Attach 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.
2 Attach the small, square connector to the printer.

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.
What is the difference between infrastructure and ad hoc
networks?
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. Devices on the wireless network must have valid IP addresses for the current network and share
the same SSID and channel as the wireless router (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.
The following table compares the characteristics and requirements of the two types of wireless networks.
Infrastructure Ad hoc
Characteristics
Communication Through wireless access point
(wireless router)
Directly between devices
Security More security options
Range Determined by range and
number of wireless access
points (wireless routers)
Restricted to range of
individual devices on network
Speed Usually faster Usually slower
Requirements for all devices
Unique IP address for each device Yes Yes
Mode set to Infrastructure mode Ad hoc mode
Same SSID Yes, including the wireless
access point (wireless router)
Yes
Same channel Yes, including the wireless
access point (wireless router)
Yes
Lexmark recommends setting up a network in infrastructure mode using the installation CD that came
with the printer.
