Solving printer communication problems
The printer and the computer cannot exchange data. You must establish bidirectional communication between the
printer and the computer. For more information, see “Bidirectional communication is not established” on
page 222.

Check your security keys
A security key is like a password. All devices on the same network must share the same security key.
Note: Make sure you copy down the security key exactly, including any capital letters, and store it in a safe place for
future reference.
The security key must follow the following criteria:
WEP key
Exactly 10 or 26 hexadecimal characters. Hexadecimal
characters are A–F, a–f, and 0–9.

The name of the network (SSID) that the printer is connected to is displayed.
7Make sure that the name of the network to which the printer is connected is the same as the name of the
network to which your computer is connected.
8If the printer and computer are connected to different networks, run the Wireless Configuration Utility to change
the wireless settings of the printer.
If you do not know the SSID of your wireless network, follow these steps to obtain it:

CHECK YOUR ADVANCED SECURITY SETTINGS
If you are using MAC address filtering to limit access to your wireless network, you must add the printer MAC
address to the list of addresses allowed to connect to your wireless access point (wireless router).
If you set your wireless access point (wireless router) to issue a limited number of IP addresses, you must change
this so that the printer can be added.
Note: If you do not know how to make these changes, see the documentation that came with the wireless...

Wi-Fi indicator light is blinking orange during installation
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 or 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:
MAKE SURE THE ACCESS...

Notes:
If you change network settings, change them on all the network devices before changing them for the wireless
access point (wireless router).
If you have already changed the wireless network settings on your wireless access point (wireless router), you
must change the settings on all the other network devices before you can see them on the network.

Your wireless network is using a unique network name (SSID). If not, it is possible that the printer/print server is
communicating over a different, nearby network that uses the same network name.
The computer you are using is connected to the same wireless network that the printer is on.
If you are using a wired (Ethernet) connection, make sure:

The Ethernet cables are correctly inserted in the Ethernet ports of your router and on the back of your printer
and/or computer.

TRY ADJUSTING EXTERNAL ANTENNAS
Generally, antennas work best if they are pointing straight up. You may find, however, that reception improves if
you experiment with different angles for your printer and/or wireless router (wireless access point) antennas.
REBOOT THE COMPUTER
Turn off and restart the computer.
PING THE WIRELESS ROUTER (WIRELESS ACCESS POINT)
Ping the wireless router (wireless access point) to make sure the network is up and running. For more information,
see “Ping the access point” on...

Notes:
If you change network settings, change them on all the network devices before changing them for the wireless
router (wireless access point).
If you have already changed the wireless network settings on your wireless router (wireless access point), you
