Make sure the network settings of the printer (e.g. network name (SSID) or network key (password), etc.) are identical with those of the wireless router. To check the settings of your smartphone/tablet, refer to the instruction manual provided with it. If the network settings of your smartphone/tablet are not identical with those of the wireless router, change the network settings of it to match with those of the wireless router. Check5 Make sure the printer is not placed too far away from the wireless router. If the distance between the printer and wireless router is too far, wireless communication becomes poor. Place the printer and wireless router close to each other. Check6 Make sure wireless signal is strong. Monitor signal status and move printer and wireless router as necessary. Place the printer and wireless router where there are no obstacles between them. Wireless communication between different rooms or floors is generally poor. Wireless communication can be impeded by building materials containing metal or concrete. If the printer cannot communicate with the computer over a Wi-Fi due to a wall, place the printer and the computer in the same room. In addition, if a device like a microwave oven that emits radio waves of the same frequency bandwidth as a wireless router is nearby, it may cause interference. Place the wireless router as far away from interference sources as possible. Check the signal strength on the touch screen. Using Touch Screen 371
