							MOVE THE COMPUTER AND/OR PRINTER CLOSER TO THE WIRELESS ACCESS POINT (WIRELESS ROUTER)
The possible distance between devices in 802.11b or 802.11g networks is 300 feet, while the wireless network range
potentially doubles in 802.11n networks. The range of your wireless network depends on many factors, including
the abilities of your router and network adapters. If you are having trouble printing, try placing the computer and
printer no more than 100 feet apart.
You can find the strength of the network signal on the printer network setup page.
CHECK MAC ADDRESS
If your network uses MAC address filtering, make sure that you include the MAC address of the printer in the MAC
address filter list. This will allow the printer to operate on the network.
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, its distance from the 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 POINT IS ON
Check the access point and, if necessary, turn it on.
MOVE YOUR ACCESS POINT TO MINIMIZE INTERFERENCE
There may be temporary interference from other devices such as microwave ovens or other appliances, cordless
phones, baby monitors, and security system cameras. Make sure your access point is not positioned too closely to
these devices.

							If your access point is using WPA or WPA2 security, then the WPA passphrase should be:
Exactly 64 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.
or
From 8 to 63 ASCII characters. ASCII characters are letters, numbers, and symbols found on a keyboard. ASCII
characters in a WPA passphrase are case-sensitive.
Note: If you do not know this information, then see the documentation that came with the wireless network, or
contact the person who set up your wireless network.
CHECK THE MAC ADDRESS
If your network uses MAC address filtering, then make sure that you include the MAC address of the printer in the
MAC address filter list. This will allow the printer to operate on the network. For more information, see “How do I

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.

Communication with printer lost when connected to Virtual Private Network (VPN)
You will lose your connection to a wireless printer on your local network when connected to most Virtual Private
Networks (VPNs). Most VPNs allow users to communicate with only the VPN and no other network at the same time.
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.
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.

							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.
Troubleshooting

							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.
