Cannot Find Machine on Wireless LAN

  1. Check1 Make sure machine is turned on.

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

    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 ON lamp flashes.

    2. Press Color button, Black button, and then Wi-Fi button in this order.

      When the ON lamp changed from flashing to lit and the Wi-Fi lamp lights up, and then the wireless LAN is enabled.

  3. Check3 If machine is temporarily connected to computer via USB cable, make sure USB cable is connected properly.

    If you set up the wireless LAN connection or change the wireless LAN settings using IJ Network Tool over a USB connection, connect the machine and the computer using a USB cable as the illustration below. The USB port is at the back of the machine.

  4. Check4 Make sure machine 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.

  5. Check5 If using IJ Network Tool, look for machine again.

  6. Check6 If searching for machine over a network, make sure machine is associated with a port. (Windows)

    If No Driver appears under Name in IJ Network Tool, the machine is not associated with a port. Select Associate Port in the Settings menu to associate a port with the machine.

  7. Check7 Make sure machine and wireless router network settings match.

    Make sure the network settings of the machine (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 machine, print out the network setting information.

  8. Check8 Make sure computer network settings are correct.

    Make sure the computer can communicate with the wireless router over the wireless LAN.

  9. Check9 Make sure machine is not placed too far away from the wireless router.

    Place the wireless router and machine 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 machine cannot communicate with the computer over a wireless LAN due to a wall, place the machine 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.

  10. Check10 Make sure wireless signal is strong. Monitor signal status and move machine and wireless router as necessary.

  11. Check11 Make sure Enable bidirectional support is selected in Ports sheet of properties dialog box of printer driver. (Windows)

  12. Check12 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.

  13. Check13 If using a router, connect machine and computer to LAN side (same network segment).

  14. Check14 If machine is connected to an AirPort Base Station via LAN, use alphanumeric characters for network name (SSID). (Mac OS)

  15. Check15 Check machine's TCP/IP setting and disable IPv6.

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

    Printing Network Settings

    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 26 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.
