Cannot Find Printer while Using Wi-Fi

  1. Check 1 Make sure printer is turned on.

    If not, make sure the printer is securely plugged in and press ON button to turn on.

    The ON lamp flashes while the printer is initializing. Wait until the ON lamp stops flashing and remains lit.

  2. Check 2 Check the network status on the touch screen.

    If the icon is displayed, Wi-Fi is disabled.

    Set Enable/disable Wi-Fi in the touch screen menu to Enable.

    If the icon is displayed, see Check 3 or later checking items to make sure whether printer setup is complete or the settings of wireless router to connect are correct.

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

    If it is not, perform setup.

    • For Windows:

      Perform setup using the Setup CD-ROM or from Setup Guide.

    • For macOS:

      Perform setup from Setup Guide.

    Note

    • IJ Network Device Setup Utility allows you to diagnose and repair the network status. Download it from the web page.

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

    Make sure the network settings of the printer (e.g. wireless router name, SSID, network key, 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 frequency band to connect to a wireless router. Match the SSID set for the printer with that for 2.4 GHz frequency band of the wireless router.

    To check the SSID set for the printer, print out the network setting information or use the operation panel to display it.

    Note

  5. Check 5 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, note that some of them have it inside.

  6. Check 6 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.

    Note

  7. Check 7 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. Check 8 Make sure Enable bidirectional support is selected in the Ports sheet of the properties dialog box of the printer driver. (Windows)

    If not, select it to enable bidirectional support.

  9. Check 9 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. Check 10 If printer is connected to an AirPort Base Station via LAN, make sure you use alphanumeric characters for network identifier (SSID). (macOS)

If the problem is not resolved, redo setup.

  • For Windows:

    Perform setup using the Setup CD-ROM or from Setup Guide.

  • For macOS:

    Perform setup from Setup Guide.
