CHECK SECURITY KEYS
If you are using WEP security
A valid WEP key is:
• 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 you are using WPA security
A valid WPA passphrase is:
• 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.
MOVE 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.
You can find the strength of the network signal on the printer network setup page.
CHECK 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.
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:
CHECK POWER
Make sure the light is on.
“Communication not available” message displays when printing
wirelessly
If you are using a laptop and have power saving settings enabled, you may see the Communication not
available message on your computer screen when you attempt to print wirelessly. This can occur if the laptop
hard drive has powered down.
If you see this message, wait a few seconds and then try to print again. The laptop and printer require a few seconds
to power up again and reattach to the wireless network.
