These are possible solutions. Try one or more of the following:
C
HECK NETWORK NAME
Make sure your network does not have the same name as another network near you. For example, if you and your
neighbor both use a manufacturer's default network name, your printer could be connecting to your neighbor's
network.
If you are not using a unique network name, consult the documentation for your wireless access point (wireless
router) to learn how to set a network name.
If you set a new network name, you must reset the printer and computer SSID to the same network name.
C
HECK SECURITY KEYS
If your wireless access point (wireless router) is using Wired Equivalent Privacy (WEP) security, the WEP key should
be:
• Exactly 10 or 26 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.
or
• Exactly 5 or 13 ASCII characters. ASCII characters are letters, numbers, and symbols found on a keyboard.
If your wireless access point (wireless router) is using Wi-Fi Protected Access (WPA) security, the WPA passphrase
should be:
• From 8 to 63 ASCII characters. ASCII characters in a WPA passphrase are case-sensitive.
or
• Exactly 64 hexadecimal characters. Hexadecimal characters are A-F, a-f, and 0-9.
If your wireless network is not using security, then you will not have a security key. Using a wireless network with
no security is not recommended because it can allow intruders to use your network resources without your consent.
M
OVE YOUR PRINTER
Move the printer closer to the wireless access point (wireless router). Although the possible distance between
devices in 802.11b or 802.11g networks is 300 feet, the maximum range for optimal performance is generally
100-150 feet.
C
HECK
MAC
ADDRESS
If your network uses MAC address filtering, make sure that you include the MAC address of the printer in the MAC
address filter list. This will allow the printer to operate on the network. For more information, see “How do I find
the MAC address?” on page 29.
Wireless print server not installed
You may see a message during installation indicating that the printer does not have a wireless print server installed.
If you are sure the printer is capable of wireless printing, try the following:
C
HECK POWER
Make sure the light is on.
