Wi-Fi indicator light is blinking orange during installation (Windows
only)
When the Wi-Fi indicator light is blinking orange, it indicates that the printer has been set up for wireless networking
but cannot connect to the network for which it has been configured. The printer may be unable to join the network
because of interference, its distance from the wireless access point (wireless router), or until its settings are changed.
These are possible solutions. Try one or more of the following:
M
AKE
SURE
THE
ACCESS
POINT
IS
ON
Check the access point and, if necessary, turn it on.
M
OVE
YOUR
ACCESS
POINT
TO
MINIMIZE
INTERFERENCE
There may be temporary interference from other devices such as microwave ovens or other appliances, cordless
phones, baby monitors, and security system cameras. Make sure your access point is not positioned too closely to
these devices.

EXTERNAL
ANTENNAS
Antennas usually work best if they are pointing straight up. You may find that reception improves if you experiment
with different angles for the printer and/or wireless access point antennas.
M
OVE
YOUR
PRINTER
Move the printer closer to the access point. 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 signal strength of the network on the network setup page.

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.
