Turn off these potential sources of interference where possible. Avoid using microwaves and cordless phones
when printing over your wireless network.
If another wireless network is operating in the vicinity, change the wireless channel on the access point.
Do not place your access point on a printer. Printers can also interfere with the wireless signal.
ARRANGE THE NETWORK TO REDUCE SIGNAL ABSORPTION
Even when the wireless signal is able to pass through an object, it is slightly weakened. If it passes through too
many objects, it can be significantly weakened. All objects absorb part of the wireless signal when it passes through
them, but certain types of objects absorb enough to cause communications problems. To avoid signal absorption,
avoid placing the following items between your access point and your printer:
• Stacks of paper or books
• Multiple walls or floors
• Crowds of people
• Objects containing water, such as fish tanks
• Plants
Place your access point as high in the room as possible to avoid signal absorption.
What is an SSID?
A Service Set Identifier (SSID) is the name that identifies a wireless network. All devices on the network must know the
SSID of the wireless network or they will not be able to communicate with each other. Usually, the wireless network
broadcasts the SSID to allow wireless devices in the area to connect to it. Sometimes, the SSID is not broadcast for
security reasons.
An SSID can contain up to 32 alphanumeric characters.
How do I find out what type of security my network is using?
You must know the security key and security mode to properly set up the printer for use on the wireless network. To
obtain this information, see the documentation that came with your wireless access point (wireless router), see the
Web page associated with the wireless access point (wireless router), or consult your system support person.
Note: The network security key is not the same as the password for the wireless access point (wireless router). The
password allows you to access the wireless access point (wireless router) settings. The security key is a WEP key or
WPA passphrase that allows printers and computers to join your wireless network.
Can I use my printer on a USB and a wireless connection at the same
time?
The printer can be configured in the following ways:
• Locally attached (connected to a computer using a USB cable)
• Wireless network
• Wireless network and locally attached simultaneously
If you want to use the printer as both a wireless and locally attached printer at the same time, you will need to run
the setup software again and select the additional connection type.
