configuration page from the printer control panel.
Wireless connectivity checklist
• Verify that the printer and the wireless router are turned on and have power. Also make sure
that the wireless radio in the printer is turned on.
• Verify that the service set identifier (SSID) is correct. Print a configuration page to determine
the SSID (see "Printing a network configuration report" on page 36).
• With secured networks, verify that the security information is correct. If the security
information is incorrect, run the wireless setup again.
• If the wireless network is working correctly, try accessing other computers on the wireless
network. If the network has Internet access, try connecting to the Internet over a wireless
connection.
• Verify that the encryption method (AES or TKIP) is the same for the printer as it is for the
wireless access point (on networks using WPA security).
• Verify that the printer is within the range of the wireless network. For most networks, the
printer must be within 30 m (100 ft) of the wireless access point (wireless router).
• Verify that obstacles do not block the wireless signal. Remove any large metal objects between
the access point and the printer. Make sure poles, walls, or support columns containing metal
or concrete do not separate the printer and wireless access point.
• Verify that the printer is located away from electronic devices that might interfere with the
wireless signal. Many devices can interfere with the wireless signal including motors, cordless
phones, security system cameras, other wireless networks, and some Bluetooth devices.
Verify that the print driver is installed on the computer.
• Verify that you have selected the correct printer port.
• Verify that the computer and printer connect to the same wireless network.
• For OS X, verify that the wireless router supports Bonjour.
