Step 2. Check the wireless signal strength If the strength of the signal for your wireless network or computer is weak or if there is interference on the wireless network, the printer might not be able to detect the signal. To determine the strength of the wireless signal, run the Wireless Network Test from the printer's control panel. (For more information, see "Step 4. Run the Wireless Network Test" on Page 28). If the Wireless Network Test indicates the signal is weak, try moving the printer closer to the wireless router. Reducing interference The following tips might help reduce the chances for interference in a wireless network: • Keep the wireless devices away from large metal objects, such as filing cabinets, and other electromagnetic devices, such as microwaves and cordless telephones, as these objects can disrupt radio signals. • Keep the wireless devices away from large masonry structures and other building structures as these objects can absorb radio waves and lower signal strength. Step 3. Restart components of the wireless network Turn off the router and the printer, and then turn them back on in this order: router first, and then the printer. If you still are unable to connect, turn off the router, printer, and your computer, and then turn them back on in this order: router first, then the printer, and finally the computer. Sometimes, turning off the power and then turning it back on will recover a network communication issue. Step 4. Run the Wireless Network Test For wireless networking issues, run the Wireless Test from the printer's control panel: 1. Make sure the printer is turned on and paper is loaded in the tray. 2. Press the (Setup) button. 3. Press the or buttons to select Print Report, and then press OK. 4. Select Wireless Test, and then press OK. If a problem is detected, the printed test report will include recommendations that might help solve the problem. 28 Solve setup problems
