C-3 : Not connected to the network No IP address is assigned. (You can also check that the item "3-2-12 IP-Address" in the printed network settings information is blank.) Check the following items. Check1 Is printer set to obtain an IP address automatically, or is wireless router requesting manual addressing? Refer to the wireless router's manual to enable DHCP (auto-acquisition) settings on the wireless router or to set a valid IP address on the printer. Check2 When you set printer's IP address manually, correct IP address may not be set. Check the network name (SSID) and the password of the wireless router you want to connect to, the IP address applicable range, and then enter the appropriate IP address on the printer side. If you are unsure, set the printer's IP address to automatic (DHCP). C-5 : Not connected to the network Unable to connect to the specified network. Check the following items. Check1 Check status of printer and network device (e.g. wireless router) and your computer/smartphone/tablet. Use 2.4 GHz frequency band to communicate with this printer and a wireless router. A typical wireless router can use the 2.4 GHz and 5 GHz frequency bands. In many cases, each frequency band is assigned a different network name (SSID). Verify the network name (SSID) and password for the frequency band you connect to. Match the network name (SSID) set for the printer with that for 2.4 GHz frequency band of the wireless router. Check2 Password on your wireless router may not match password you entered. Passwords are case sensitive. Enter the password correctly. Check3 Monitor signal status and move printer and wireless router as necessary. • Monitor the signal status and move the printer and the 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. • After changing the installation location, print out the network settings information again and check the status of the signal. Compare with the value in section "3-2-1 Signal Strength" in the printed network settings information to determine the installation location. Check4 Check wireless channel number of Wi-Fi you are using on computer. 247
