Choose which connection method to use
The following methods can be used to connect your printer.
Connection
type Speed Cable length Other factors
Wireless Moderate; varies according to
conditions (distance to router,
interference, number of wireless clients,
network topology, etc.) N/A Sensitive to interference over longer
distances; requires extra equipment
(wireless access point or wireless router)
Fast Ethernet Fast; varies according to network traffic Long: 100 m (328
ft) Requires extra equipment (switches)
Hi-Speed USB Very fast Short: 3 m (10 ft) A certified Hi-Speed USB cable is
necessary for reliable communication.
NOTE: The speed of any network connection depends on all components used in the network, which
can include network interface cards, routers, switches and cables. If any one of these components
cannot operate at high speed, you will have a low-speed connection. The speed of your network
connection can also be affected by the total amount of traffic from other devices on the network.
Connect the printer to your network
The printer is able to configure itself automatically for most networks, in a similar way to any computer
in the same network. The first time you connect it to a network, this process may take a few minutes.
Once the printer has a working network configuration, you can check its network address from the front
panel: press or .
To connect to a wireless network, the easiest way is to go to the front panel and press , then
Connectivity > Wireless setup wizard.
When a network device automatically configures itself by receiving an IP address from the DHCP
service, this IP address may change from the last time the device is powered off to the next time it is
powered on, which may lead to the device being shown as "offline" when driver port settings are
configured with the original IP address. There are at least three possible ways to avoid this:
● Increase the lease time of your DHCP server device.
● Set a fixed IP address for your printer that will not be changed by DHCP (see Communication
failures between computer and printer on page 121 ).
● Configure the printer and driver to refer to the hostname instead of the numeric IP address (see
Communication failures between computer and printer on page 121 ).
