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. Wireless print server not installed You may see a message during installation indicating that the printer does not have a wireless print server installed. If you are sure the printer is capable of wireless printing, try the following: CHECK POWER Make sure the light is on. "Communication not available" message displays when printing wirelessly 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 more information on locating IP addresses, refer to "How do I locate IP addresses?" on page 30. 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 Shut down the device that does not have a valid IP address (the laptop, the printer, or both). 2 Turn on the device(s). 3 Check 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. Make sure your wireless access point (wireless router) is working, and remove any obstacles that could be blocking the wireless signal. 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. Troubleshooting a printer on a wireless network 22
