							“Communication not available” message displays when printing wirelessly
These are possible solutions. 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, 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.
If you see this message again after you have waited long enough for the printer and the laptop to attach to the
network, there may be a problem with your wireless network.
Make sure that the laptop and printer have both received IP addresses:
For Windows users
1Click , or click Start and then click Run.
2In the Start Search or Run box, type cmd.
3Press Enter, or click OK.
The Command Prompt window opens.
4Type 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
1From the Apple menu, choose About This Mac.
2Click More Info.
3From the Contents pane, choose Network.
4If you are connected over a wireless network, choose AirPort from the Active Services list.
How to locate a printer IP address
You can locate the printer IP address by viewing the printer network setup page.
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):
1Turn off the device that does not have a valid IP address (the laptop, the printer, or both).
2Turn on the device(s).
3Check the IP addresses again.
If the laptop and/or printer still does not receive a valid IP address, there is a problem with your wireless network.
Try the following:
Make sure your wireless 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, it is possible that the printer is
not receiving the IP address within the allowed time.
Make sure your DHCP server, which may also be your wireless router, is working and is configured to assign IP
addresses. If you are not sure how to do this, refer to the manual that came with your wireless router for more
information.
If the printer and computer have valid IP addresses and the network is operating correctly, continue
troubleshooting.

							Resolving intermittent wireless communications issues
You may notice that your printer works for a short time and then stops working, although apparently nothing has
changed on your wireless network.
Many different issues can interrupt network communications, and sometimes more than one problem exists at the
same time. These are possible solutions. Try one or more of the following:
DISCONNECT FROM ALL VPNS WHEN ATTEMPTING TO USE THE WIRELESS NETWORK
Most Virtual Private Networks (VPNs) allow computers to communicate with only the VPN and no other network
at the same time. Disconnect from the VPN before installing the driver on the computer or before running the
wireless setup on the computer.
To check if the computer is currently connected to a VPN, open your VPN Client software and check your VPN
connections. If you do not have a VPN Client software installed, check the connections manually using the Windows
VPN Client.
If you would like to have the ability to connect to your local network and to a VPN at the same time, the system
support person for the VPN must enable split tunneling. Be aware that some organizations will not allow split
tunneling due to security or technical concerns.
TURN OFF THE WIRELESS ACCESS POINT (WIRELESS ROUTER) AND TURN IT BACK ON AGAIN
ELIMINATE NETWORK CONGESTION
If a wireless network is too busy, the computer and printer may have difficulty communicating with each other.
Some causes of wireless network congestion can include:
Transferring large files across the network
Networked games
Peer-to-peer file swapping applications
Streaming video
Too many computers on the wireless network at once
ELIMINATE SOURCES OF INTERFERENCE
Common household items can potentially disrupt wireless network communications. Cordless phones (but not
cellular phones), microwave ovens, baby monitors, almost any kitchen appliance, wireless surveillance equipment,
nearby wireless networks, and any appliance containing a motor can disrupt wireless network communications.
Try turning on any potential sources of interference and see if it causes the problem. If it does, separate your wireless
network from the device.
CHANGE THE CHANNEL THE WIRELESS ROUTER USES
You can sometimes eliminate interference from unknown sources by changing the channel your wireless router
uses to broadcast. There are three distinct channels on a router. Check the documentation that came with your
router to determine which three apply. Other channels are offered as options, but these overlap. If the router is
configured to use the default settings, change the channel setting to use a different distinct channel. Refer to the
manual that came with your wireless router if you are not sure how to change the channel.

							CONFIGURE THE WIRELESS ROUTER WITH A UNIQUE SSID
Many wireless networks use the SSID that the router was originally configured by the manufacturer to use. Using
the default SSID can cause problems when more than one network is operating in the same area with the same
SSID. The printer or computer may attempt to attach to the wrong network, although it will appear to be trying to
connect to the correct network.
To avoid this type of interference, change the SSID on your wireless router from the default. Refer to the manual
that came with your router if you are not sure how to change the SSID.
Note: You must change the SSID on all of the other devices that access your wireless network if you change the
SSID on the router.
ASSIGN STATIC IP ADDRESSES TO ALL DEVICES IN THE NETWORK
Most wireless networks use a DHCP server (dynamic host configuration protocol) built in to the wireless router to
assign IP addresses to clients on the wireless network. DHCP addresses are assigned when they are needed, as
when a new device is added to the wireless network or when it is powered on. Wireless devices must send a request
to the router, and receive an IP address in response so they can function on the network. Because the router
performs many other tasks besides assigning addresses, it sometimes does not respond quickly enough with an
address. The requesting device sometimes gives up before it receives an address.
Try assigning static IP addresses to the devices in your network to resolve this issue. Static IP addresses cut down
on the work your wireless router has to do. Refer to the manual that came with your router and your operating
system documentation if you are not sure how to assign static IP addresses.
To assign a static IP address to the printer, do the following:
1Complete the wireless setup, allowing the printer to receive a DHCP address from a DHCP server on the network.
2Print a network setup page to see what IP address is currently assigned to the printer.
3Open a Web browser and then type the printer IP address in the address field. Press Enter.
The printer Web page loads.
4Click the Configuration link.
5Click the TCP/IP link.
6Click the Set Static IP Address link.
7Type the IP address you want to assign to the printer in the IP Address field.
8Click the Submit button.
The Submitting Selection message appears.
Confirm that the IP address is updated by typing the static IP address in the browser address field and checking to
see if the printer Web page reloads.
CHECK FOR KNOWN ISSUES WITH THE WIRELESS ROUTER
Some wireless routers have documented defects that were identified and resolved by the manufacturers. Visit the
company Web site of the router manufacturer. Check for firmware updates and other advice from the manufacturer.
Check the manual that came with your wireless router if you are not sure how to reach the manufacturer Web site.

							CHECK FOR WIRELESS ADAPTER UPDATES
If you are having trouble printing from one particular computer, check the Web site of the manufacturer of the
network adapter card in that computer. It is possible that there is an updated driver available that could resolve
the issue.
CHANGE ALL NETWORK DEVICES TO THE SAME TYPE
While it is possible to successfully mix 802.11b, 802.11g, and 802.11n devices on the same wireless network, the
faster devices will sometimes prevent the slower devices from communicating. Wireless devices are designed to
wait for a gap in wireless network communications before attempting to send information. If newer, faster devices
are constantly using the wireless network, then older, slower devices will not have a chance to send data.
Try only turning on the network devices of the same type and see if network communications improve. If this solves
the problem, you may want to upgrade your older devices with newer network adapters.
PURCHASE A NEW ROUTER
If your router is several years old, it may not be fully compatible with the newer wireless devices on your network.
Consider purchasing a newer router that is fully compliant with the 802.11 IEEE specifications.
