Cannot Find Printer while Using Wireless LAN


  1. Check1 Check the power status of printer and other devices (wireless router, PC, smartphone, or tablet).

    Turn on the printer or devices.

    If the power is already turned on, turn it off and on again.

  2. Check2 Make sure Wi-Fi lamp is lit on operation panel.

    If the Wi-Fi lamp is off, the wireless LAN is disabled. Follow the procedure below to enable the wireless LAN.

    1. Press and hold Wi-Fi button and release it when Wi-Fi lamp flashes.

    2. Press Black button.

    3. Press the Wi-Fi button repeatedly until the Network lamp lights.

    4. Press Color button or Black button to finalize selection.

  3. Check3 Make sure printer setup is complete.

    If it is not, perform setup.

    • For Windows:

      Use the Setup CD-ROM or follow the instructions on the Canon website.

    • For Mac OS:

      Follow the instructions on the Canon website.

  4. Check4 If you can use IJ Network Device Setup Utility, look for printer again. (Windows)

  5. Check5 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.

    To check the current network settings of the printer, print out the network setting information.


    • For Windows, you can use IJ Network Device Setup Utility to change printer's settings according to those of wireless router.
  6. Check6 Make sure the printer is not placed too far away from the wireless router.

    Place the wireless router and printer 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 wireless LAN 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.


    • Though an antenna is attached to most wireless routers, note that some of them have it inside.
  7. Check7 Make sure wireless signal is strong. Monitor signal strength and move printer and wireless router as necessary.

    To check the signal strength:

  8. Check8 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.

  9. Check9 Make sure Enable bidirectional support is selected in the Ports sheet of the properties dialog box of the printer driver. (Windows)

  10. Check10 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. Some programs use a firewall by default.

  11. Check11 If printer is connected to an AirPort Base Station via LAN, use alphanumeric characters for network identifier (SSID). (Mac OS)

  12. Check12 Check printer's TCP/IP setting and disable IPv6.

    To check the current TCP/IP setting, print out the network setting information using the operation panel.

    If "TCP/IPv6" is set to "Enable", both IPv4 and IPv6 are enabled.

    Press and hold Stop button and release it when Alarm lamp flashes 23 times.

    IPv6 is disabled and only IPv4 is enabled.


If the problem is not resolved, redo setup.

  • For Windows:

    Use the Setup CD-ROM or follow the instructions on the Canon website.

  • For Mac OS:

    Follow the instructions on the Canon website.
