Solving other problems
If problems occur while using the machine on a network, check the followings.
For information on Access Point (or wireless router), refer to its own user's guide.
• Your computer, access point or machine may not be turned on.
• Check the wireless reception around the machine. If the reception is far from the
machine or there is an obstacle, you might have difficulty receiving the signal.
• Cycle the power for Access Point (or wireless router), machine and computer.
Sometimes cycling the power can recover network communication.
• Check whether firewall software (V3 or Norton) is blocking the communication.
If the computer and the machine is connected on a same network it cannot be searched,
firewall software might be blocking the communication. Refer to the user's guide for the
software to turn it off and try searching the machine again.
• Check whether the machine's IP address is allocated correctly. You can check the IP
address by printing the network configuration report.
• Check whether Access Point (or wireless router) has a configured security (password). If
it has a password, refer to the Access Point (or wireless router) administrator.
• Check whether the machine's IP address. Reinstall the machine driver and change the
settings to connect to the machine on the network. Due to the characteristics of DHCP,
the allocated IP address could change if the machine is not used for a long time or if the
Access Point has been reset.
• Check the wireless environment. You might not be able to connect to the network in the
infrastructure environment where you need to type in a user's information before
connecting to Access Point (or wireless router).
