Cannot Find Printer on Network

1. Check1 Check power status.

   Check your printer and the network device (wireless router, etc.) are turned on.

   If you are in the process of setting up, interrupt it and check if the wireless router (modem) is turned on and then check if the printer is turned on.

   1. Check if network device such as router is turned on.

      If network devices are not turned on, turn on the power. If the network devices are on, turn them off and on again.

      It may take a while for the network device to become ready for use once they are turned on.

      Proceed once the network device such as router is ready for use.

   2. Check if printer is turned on

      If printer is not turned on, turn on the power. If the printer is on, turn it off and on again.

   Proceed once you complete checking the power status above.

2. Check2 Check PC network connection.

   If your computer and network devices (wireless router, etc.) are fully configured, your computer is ready to connect to the network.

   1. Check the settings of the network device (wireless router, etc.).

      Connect to the Internet and see if you can browse any web page. If you cannot view web pages on your computer, check wireless router network connection settings, such as IP address filtering, MAC address filtering, and DHCP function.

      To check the network name (SSID) of the wireless router the printer is connected to, print the network settings.

      • Printing Network Settings

      Note

      • Depending on the wireless router, note that different network name (SSID) is assigned for a bandwidth (2.4 GHz or 5 GHz) or its usage (for PC or game machine), using alphanumeric characters at the end of network name (SSID).

      • For more on checking the settings of the wireless router, refer to the instruction manual supplied with the wireless router or contact the manufacturer.

      If you use an encryption key, specify it for the network name (SSID) you are using. For details, see Setting an Encryption Key.

   2. Check PC network connection.

      For the procedures, refer to the instruction manual supplied with the computer, or contact the manufacturer.

   Once you complete setting up the wireless router and your computer, configure the settings on your computer in order to view web pages, using the information of the wireless router.

   Proceed once you complete checking the network connection above.

3. Check3 Check printer's Wi-Fi settings.

   Make sure icon is displayed on the LCD when Setup button is pressed.

   Note

   • When you press the Setup button, the icon is displayed only for a short time.

     Press the Setup button to display the icon again.

   If or icon is not displayed:

   The printer is not set to use Wi-Fi.

   From the Setup menu screen, select Device settings > LAN settings > Wi-Fi > Wi-Fi enab./disable in this order and select Enable.

   If icon is displayed:

   icon indicates that the wireless router and the printer are not connected. Reconsider the locations of the wireless router and the printer. Also, revisit the location of the wireless router and printer at the next check.

4. Check4 Check location of wireless router.

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

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

   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.

Diagnose and repair the network connections using Wi-Fi Connection Assistant.

Download Wi-Fi Connection Assistant from the below page, and install it on your computer.

• Checking Printer Connection Status Using Wi-Fi Connection Assistant

Refer to below in regard to starting up Wi-Fi Connection Assistant.

• For Windows:

  • Starting Up Wi-Fi Connection Assistant

• For macOS:

  • Starting Up Wi-Fi Connection Assistant

1. Check1 Make sure Enable bidirectional support is selected in Ports sheet of Printer properties dialog box. (Windows)

   If not, select it to enable the bidirectional support.

2. Check2 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.

3. Check3 If printer is connected to AirPort Base Station via LAN, make sure you use alphanumeric characters for network name (SSID). (macOS)

4. Check4 Solve network troubles manually.
