“Communication not available” message appears 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 reconnect to the wireless network.

If you see this message again after you have waited long enough for the printer and the laptop to connect 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

1Open the command window.

In Windows 8

From the Search charm, type run, and then navigate to: Apps list > Run > type cmd > OK

In Windows 7 or earlier

aClick , or click Start and then click Run.

bIn the Start Search or Run dialog, type cmd.

cPress Enter, or click OK.

2Type 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, navigate to: About This Mac > More Info

2From the Contents pane, choose Network.

3If you are connected over a wireless network, then 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.

From the printer control panel, navigate to either of the following:

> Setup >> Network Setup >> Wireless 802.11 b/g/n >> Network Connection

Setup > > TCP/IP > > IP Address >

> Setup > > Network Setup > > Ethernet 10/100 > > Network Connection

Setup > > TCP/IP > > IP Address >

If the printer 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), then do the following:

1Turn off the device that does not have a valid IP address (the laptop, the printer, or both).

2Turn on the device, and then check the IP addresses again.

If the printer or the laptop 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

networkintensive 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.

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, then refer to the manual that came with your wireless router.

If the printer and computer have valid IP addresses and the network is operating correctly, then continue troubleshooting.

MAKE SURE THE WIRELESS PORT IS SELECTED

Note: This solution applies to Windows users only.
