							Wireless network setup312. Using a network-connected machine
From the computer
From the computer, we recommend using a USB cable with the 
program provided in the supplied software CD. 
See "Setup using Windows" on page 37.
•With a USB cable: You can simply set up a wireless network 
using the program on the supplied software CD. Only Windows 
and Macintosh operating systems are supported (see "Setup 
using Windows" on page 37 or "Setup using Macintosh" on page 
45).
 
You can also install a wireless network in Printer Settings 
Utility with a USB cable after installing the driver (Windows 
and Macintosh operating systems are supported).
 
•With a network cable: You can set up a wireless network using 
the SyncThru™ Web Service program (see "Using a network 
cable" on page 51).

Using the WPS button 
If your machine and an access point (or wireless router) support Wi-
Fi Protected Setup™ (WPS), you can easily configure the wireless 
network settings by pressing the   (WPS) button on the control 
panel without a computer.
 
If you want to use the wireless network using the 
infrastructure mode, make sure that the network cable is 
disconnected from the machine. Using the WPS (PBC) 
button or entering the PIN from the computer to connect to 
the access point (or wireless router) varies depending on the 
access point (or wireless router) you are using. Refer to the 
user's guide of the access point (or wireless router) you are 
using.
 
Items to prepare
• Check if the access point (or wireless router) supports Wi-Fi 
Protected Setup™ (WPS).
• Check if your machine supports Wi-Fi Protected Setup™ (WPS).
• Networked computer (PIN mode only)

							Wireless network setup322. Using a network-connected machine
Choosing your type
There are two methods available to connect your machine to a 
wireless network using the   (WPS) button on the control panel.
The Push Button Configuration (PBC) method allows you to 
connect your machine to a wireless network by pressing both the   
(WPS) button on the control panel of your machine and the WPS 
(PBC) button on a Wi-Fi Protected Setup™ (WPS)-enabled access 
point (or wireless router) respectively.
The Personal Identification Number (PIN) method helps you 
connect your machine to a wireless network by entering the 
supplied PIN information on a Wi-Fi Protected Setup™ (WPS)-
enabled access point (or wireless router).
For machines with an display screen, factory default in your machine 
is PBC mode, which is recommended for a typical wireless network 
environment.
 
To change the WPS mode from the control panel, press   
(Menu) > Network > Wireless > OK > WPS Setting.
 
Machines with an display screen
►Connecting in PBC mode

more than 2 seconds.
The machine starts waiting for up to two minutes until you 
press the WPS (PBC) button on the access point (or wireless 
router).
2 Press the WPS (PBC) button on the access point (or wireless 
router).

Re-connecting to a network
When the wireless function is off, the machine automatically tries to 
re-connect to the access point (or wireless router) with the 
previously used wireless connection settings and address.
 
In the following cases, the machine automatically re-
connects to the wireless network:
• The machine is turned off and on again.
• The access point (or wireless router) is turned off and on 
again.
 
Canceling the connection process
To cancel the wireless network connection when the machine is 
connecting to the wireless network, press and release the   (Cancel

Using the menu button
Before starting, you will need to know the network name (SSID) of 
your wireless network and the network key if it is encrypted. This 
information was set when the access point (or wireless router) was 
installed. If you do not know about your wireless environment, 
please ask the person who set up your network.
 
After completing the wireless network connection, you need 
to install a machine driver to print from an application (see 
"Installing driver over the network" on page 17).
 
1Press the   (Menu) button on the control panel.
2 Press Network > OK > Wireless > OK > WLAN Settings > OK.

8 The window shows the wireless network settings and checks 
if the settings are correct. Click Next.
• For the DHCP method
If the IP address assignment method is DHCP, check if 
DHCP is shown in the window. If it shows Static, click 
Change TCP/IP to change the assignment method to 
DHCP.
• For the Static method
If the IP address assignment method is Static, check if 
Static is shown in the window. If it shows DHCP, click 
Change TCP/IP to enter the IP address and other network 
configuration values for the machine. Before entering the 
IP address for the machine, you must know the computer’s

For example:
If the computer’s network information is as shown below:
- IP address: 169.254.133.42
- Subnet Mask: 255.255.0.0
Then, the machine’s network information should be as 
follows:
- IP address: 169.254.133.43 - Subnet Mask: 255.255.0.0 (Use the computer’s subnet 
mask.)
