Before you proceed to Troubleshooting, confirm the following:

z The USB cable is securely connected to the correct port.

z The MP driver is already installed.

z The machine is turned on. If it is, turn it off and then turn it on again.

z There is no barrier or obstacle between the access point and the machine.

Although wireless communication between rooms or floors is possible, the wireless 
communication quality may become poor. The wall must be made of a material that allows radio 
waves to pass through.
If the wall material prevents communication, set the machine in the same room as the access 
point.

z Printing via USB connection is possible.

z The firewall feature of security software may prevent proper setup or communication over a 

network.
When setting up the machine for use over a network, disable the firewall of your security software 
during the setup.
If you are using Windows XP Service Pack 1 or earlier and you have Internet Connection Firewall 
enabled, a dialog box asking you for confirmation to disable the firewall will appear during setup. 
Click [Yes] to disable the firewall. When setup is complete, the firewall will be re-enabled 
automatically.
To confirm the version of your Windows XP, see 

“Confirming the version of Windows XP” on 

page 71

.

z When using a router, connect the machine and computer to the LAN side (same network 

segment).
