Cannot Find Printer while Using Wi-Fi

  1. Check1 Make sure printer is turned on.

    If not, make sure that the power cord is plugged in securely or the battery is attached correctly and press the ON button to turn on the printer.

  2. Check2 Check the icon on LCD.

    The icon appears on the LCD.

    If the icon is not displayed, select (Setup) on HOME screen > LAN settings > Wi-Fi > Advanced mode and then select Enable.

    If the icon is displayed, it indicates that Wi-Fi communication is not possible with the current settings. See Check 3 or later checking items.

  3. Check3 Make sure printer setup is complete on the computer.

    If it is not, click here and perform setup.

    Note

  4. Check4 Make sure printer and wireless router network settings match.

    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 the wireless router, refer to the instruction manual provided with it or contact its manufacturer.

    Note

    • Use 2.4 GHz or 5 GHz frequency band to connect to a wireless router. Match the network name (SSID) set for the printer with that for 2.4 GHz or 5 GHz frequency band of the wireless router.

    To check the network name (SSID) set for the printer, display it using the operation panel of the printer or print out the network setting information of the printer.

    Note

  5. 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.

    Note

    • Though an antenna is attached to most wireless routers, some of them have it inside.

  6. Check6 Make sure wireless signal is strong. Monitor signal strength 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 LCD.

    Note

  7. Check7 Make sure the computer is connected to the wireless router.

    For more on how to check the computer settings or connection status, see your computer instruction manual or contact its manufacturer.

    Note

    • If you use a smartphone or tablet, make sure the Wi-Fi is enabled on the device.

  8. Check8 Make sure Enable bidirectional support is selected in the Ports sheet of the Printer properties dialog box. (Windows)

    If not, select it to enable bidirectional support.

  9. Check9 Make sure security software's firewall is off.

    If your security software's firewall is on, a message may appear warning you that Canon software is attempting to access the network. If this warning message appears, set security software to always allow access.

    If you are using any programs that switch between network environments, check their settings.

  10. Check10 If printer is connected to an AirPort Base Station via LAN, make sure you use alphanumeric characters for network name (SSID). (macOS)

  11. Check11 Make sure of the default printer in the Control Panel. (Windows)

    Select Devices and Printers in the Control Panel and make sure that your printer is marked as default. If it is not marked, set it as the default printer.

If the problem is not resolved, click here and redo setup.
