Setting the wireless LAN
For more information, see the instruction manual for the network device you are using, or contact the networking device manufacturer.
Step1 Checking Before the Setup
The setup of the computer and wireless LAN/access point should be completed.
If they are not set up, you will not be able to use the machine on the wireless LAN network even if you perform the following steps.
Once you have checked the connection settings, proceed to “Step2 Switching the Connection Method to Wireless LAN”
on the next page.
Precautions when connecting to a wireless LAN
• The structure of your computer or networked device, the existence of router functions, setting methods and security settings vary depending on your
environment.
• You can connect the machine to wireless LANs or wired LANs, but you cannot use both at the same time. When using a wireless LAN connection, do not
connect a LAN cable to the machine. This may cause the machine to malfunction.
• If using the machine in your office, consult with your network administrator.

Cause When searching for an access point, the WPS button on the wireless LAN router or access point
was not pressed within 2 minutes.
Solution Specify the settings again.
Proceed to “Step4-A Setting the Machine Using the WPS (Push Button Mode),” on P.1-4.
Check the network connection if the message still appears.
Proceed to “Checking Network Connections,” on P.2-6.
WPS – When specifying the settings in push button mode
