Notes on Wi-Fi Connection

Important

  • If a device is connected to the Internet via a wireless router, and you then connect it to a printer in Wireless Direct mode, the existing connection between the device and wireless router will be disabled. In that case, the connection of the device may switch to a mobile data connection automatically depending on your device. When you connect to the Internet using a mobile data connection, charges may apply depending on your contract.

    • When you connect a device and the printer using Wireless Direct, the connection information will be saved to Wi-Fi settings. The device may be connected to the printer automatically even after disconnecting it or connecting it to another wireless router.
    • To prevent automatic connection to the printer in Wireless Direct mode, change the connection mode after using the printer, or set not to connect automatically in the Wi-Fi settings of the device.
      For details on changing the settings of your device, see the manual supplied with the device or contact its manufacturer.
  • If you connect a device and the printer using Wireless Direct, Internet connection may become unavailable depending on your environment. In that case, web services for the printer cannot be used.
  • If a device is already connected to a network, you cannot connect it to a printer in Wireless Direct mode. Disable the connection to the network, and then proceed with the setup.
  • In Wireless Direct mode, you can connect up to five devices at the same time. If you try to connect a sixth device while five devices are already connected, an error will appear.
    If an error appears, disconnect a device that does not use the printer, and then redo the settings.
  • When connecting to Wi-Fi outdoors, do not connect to a 5 GHz network (SSID).
    The 5 GHz band available for use with the printer includes the channels that are allowed for indoor use only, depending on your country or region.
    For details on the 5 GHz network (SSID) of your wireless router, see the manual supplied with the wireless router, or contact its manufacturer.
  • Devices connected to the printer using Wireless Direct cannot communicate with each other.
  • Firmware updates for the printer are not available while using Wireless Direct.
  • When a device has been connected to the printer without using a wireless router and you want to set it up again using the same connection method, disconnect it first. Disable the connection between the device and printer in the Wi-Fi setting screen.
