Cannot Find Machine on Wireless LAN

  1.   Make sure machine is turned on.

  2.   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 the Wi-Fi button and release it when the ON lamp flashes.

    2. Press the Color button, the Black button, and then the 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.   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.   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. If using IJ Network Tool, look for machine again.

  6.   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.   Make sure machine and wireless router network settings match.

    See instruction manual provided with wireless router or contact its manufacturer to check wireless router settings, and then modify machine settings to match.

  8.  Check for obstructions.

    Wireless communication between different rooms or floors is generally poor. Move the machine and wireless router as necessary.

    To check  the radio status,

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

    The machine can be up to 50 m (164 ft) from the wireless router indoors. Make sure the machine is close enough to the wireless router to be used.

    To check  the radio status,

  10.  Make sure there is no source of radio wave interference nearby.

    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.

    To check  the radio status,

  11.   Make sure computer network settings are correct.

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

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

  13.   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.

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

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

  16.  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", IPv4 and IPv6 are enabled.

    Press and hold the Stop button and release it when the 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.
