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.

Troubleshooting
When an Error Message Appears
“Could not connect. More than one access point was detected.”
Cause Other wireless LAN routers or access points within the connection range were detected.
Solution Wait a few moments and specify the settings again.
Proceed to “Step4-A Setting the Machine Using the WPS (Push Button Mode),” on p.1-4.
”WPS connection failed.”
Cause An error occurred while specifying the settings using the WPS function, resulting in a connection
failure.

“Cannot nd access point.”
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
Cause The machine cannot detect the wireless LAN routers or access points because there is a problem
with the network connection.
Solution Check the network connection.
Proceed to “Checking Network Connections,” on p.2-6.

“Open authentication failed. Check WEP settings.”
Cause Connection failed because the authentication method is set to <Open System> for the machine
and “Shared Key” set for the wireless LAN router or access point you are using.
Solution Manually set the authentication method of this machine to <Shared Key>
according to the wireless LAN router or access point you are using.
