Troubles in Setup/Connections
1 Connection checklist
Before you proc eed to Troubleshooting, conf irm the following:
2.1 The target access point is not detected
Refer to “1 Con nection checklist” on page 2 and mak e sure there is no problem.
If the machine or your computer cannot communicate with the target access point, follow the
procedure below.
•
•
a
Ensure that the access point is o n and then click Update in the Acces s Points dialog box.
b
If the access point is still not detected, move your machine closer t o the access point and
remove possible obstructions, then click Update.
c
Ensure that your computer can com municate with the access point.
d
Unplug the access point from the power outlet and plug it in, then cl ick Update.
Using your acce ss point’s utility software, check if your acce ss point is set to the stealth mode,
i.e., set not t o broadcast its SSID, or is set to r eject clients whose SSID is set to ANY. If so, click
Manual Setup and enter the access point’s SSID in SSID. For de tails, refer to “5.1 The Access
Points dialog b ox is displayed during setup” on pag e 4.

2.3 Using the machine in a multiple access point setup
Confirm the fol lowing the access point to be used c an communicate with the machine and the

If multiple net works are available when using Macin tosh, select System Preferences, select
Network, select AirPort and click Advanced (Mac OS X v.10.4.x/v.10.3.9: select Network Port
Configuration), then change the priority of the network name that you want to use. If the network
name is not set to the highest priority, select and mo ve it to the top of the list (the hi ghest priority).
2 Cannot connect to the access point (the access point is not detected)
The USB cable i s securely connected to the correct port.
The machine is turned on and the network device is on.
If it is, turn it off and then turn it on again.
If the firewall function of your security software is turned on, a message may appear w arning that
Canon software is attempting to access the network. If the warning message appears, set the secu-
rity software t o always allow access.
When using a ro uter, connect the machine an d computer to the LAN side (same net work segment).
The machine’s LAN setting is configured according to your conn ection method.
To connect over wireless LAN, set Change wireless/wired to Wi reless LAN active. To connect
over wired LAN, set it to Wired LAN active.
For the procedu re, refer to “Machine’s LAN Setting” in the pri nted manual: Getting Started.
If you have cha nged the machine’s LAN setting, set up the mach ine again following the procedures

2.1 The target access point is not detected (continued)
The wireless ch annel to be used may be limited depe nding on wireless network devices in stalled
in the computer. Confirm the wireless chann els available for the network device . For details,
refer to the ma nual provided with your computer or your wireless network device. Make s ure that
the channel set to the access point is valid to com municate with the computer, confirmed above.
If not, change the channel set to the access point.
If MAC address filtering is enabled, we recommend that you register the machine’s MAC address
to the access p oint before entering setup. To confi rm the MAC address of the machine, r efer to
“About Network Communication” - “Troubleshooting” in the on-screen m anual: Advanced Guide.
If the access p oint’s IP address filt ering is enabled, disable it during setup. After setup is complete, turn the IP filteri ng feature back on.
If Client-to-Cl ient Blocking is enabled, an access point may be capable of blocking all direct
transmission am ong clients associated to it. If suc h feature is enabled, disable this f eature while
using the machi ne.

2.2 Cannot connect to the target access point
Refer to “1 Con nection checklist” on page 2 and mak e sure there is no problem.
Confirm the net work name/SSID of the target access point and set the machine to use the identical network nam e/SSID. If the network name/SSID is different i n the machine and the access
point, the mach ine cannot connect to the access poi nt. For details, refer to “5.1 The Acce ss
Points dialog b ox is displayed during setup” on pag e 4.

•
This machine does not support WPA/WPA2-Enterprise. When you select an access point
set to use WPA/WPA2-Enterprise, it is grayed out and cannot be set up.
•
Make sure that the machine and the access point can communicate with each other under t his
setting. When e ncryption is set to the access point , set up the encryption of the machi ne to
match the setti ngs of the access point. If the WEP/ WPA/WPA2 (encryption key) is different in
the machine and the access point, the machine canno t communicate with the access point. For
details, refer to “3.2 How to set a WEP/WPA/WPA2 key” on page 3.
