Troubleshooting In Mac OS X version 10.4 or earlier 1 From the Finder, navigate to: Applications > Internet Connect > AirPort The SSID of the network that the computer is connected to is displayed in the Network menu. 2 Write down the SSID. For Macintosh users with an access point 1 Type the IP address of the access point in the address field of your Web browser, and then continue to step 2. If you do not know the IP address of the access point, then do the following: a From the Apple menu, navigate to: System Preferences > Network > AirPort b Click Advanced or Configure. c Click TCP/IP. The Router entry is typically the access point. 2 Type your user name and password when prompted, and then click OK. 3 In the Wireless settings section, look for the SSID. 4 Write down the SSID, security type, and the WEP key/WPA passphrase (if shown). Notes: • Make sure you copy the network information down exactly, including any capital letters. • Store the SSID and the WEP key or WPA passphrase in a safe place for future reference. MAKE SURE YOUR OS IS COMPATIBLE WITH WIRELESS PRINTING THROUGH AIRPORT The printer supports wireless printing only through AirPort base stations for Mac OS X version 10.5 or later. "Communication not available" message displays when printing wirelessly Try one or more of the following: MAKE SURE YOUR COMPUTER AND PRINTER HAVE VALID IP ADDRESSES FOR THE NETWORK If you are using a laptop and have power saving settings enabled, then 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, then 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. 52 If you see this message again after you have waited long enough for the printer and the laptop to attach to the network, then there may be a problem with your wireless network. Make sure that the laptop and printer have both received IP addresses: For Windows users 1 Click , or click Start and then click Run. 2 In the Start Search or Run box, type cmd. 3 Press Enter, or click OK. 4 Type ipconfig, and then press Enter. The IP address appears as four sets of numbers separated by periods, such as 192.168.0.100. For Macintosh users 1 From the Apple menu, navigate to: About This Mac > More Info 2 From the Contents pane, choose Network. 3 If you are connected over a wireless network, choose AirPort from the Active Services list. The Router entry is typically the access point. Locating the printer IP address • From the printer, print a network setup page. In the TCP/IP section, look for Address. • View the printer settings. 1 From the printer control panel, navigate to: > Network Setup > TCP/IP > IPv4 2 Look for IP Address. If the printer and/or the laptop does not have an IP address, or if either has an address of 169.254.x.y (where x and y are any two numbers between 0 and 255): 1 Turn off the device that does not have a valid IP address (the laptop, the printer, or both). 2 Turn on the device(s), and then check the IP addresses again. If the laptop and/or printer still does not receive a valid IP address, then there is a problem with your wireless network. Try the following: • Make sure your access point (wireless router) is turned on and is working. • Remove any objects that could be blocking the signal. • Temporarily turn off any unnecessary wireless devices on your network and pause any network‑intensive activities, like large file transfers or network games. If the network is too busy, then it is possible that the printer is not receiving the IP address within the allowed time.
