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 pri nt 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.
If you see this message again after you have waited long enough for the printer and the laptop to attach
to the network, then th ere may be a prob lem with your wire less 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.
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, 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:
> Setup > OK > Network Setup > OK > Wireless 802.11 b/g/n > OK > Network Connection
Setup > OK > TCP/I P > OK > IP Address > OK
If the printer or the laptop does not have an IP address, or if either has an address o f 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
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.
•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 t o the manual that came with
your wireless router.
