Restrictions

The printer cannot use a wired LAN connection simultaneously with a Wi-Fi or wireless direct connection.

When connecting another device while a device (such as a computer) is already connected to the printer, connect using a method other than the above.

Using a wired LAN connection and a Wi-Fi connection, or a wired LAN connection and a wireless direct connection at the same time, will disconnect the computer or other devices that were being used.

Connect via wireless router

  • The printer cannot use wireless and wired connections simultaneously.
  • Make sure your device and the wireless router are connected. For details on checking these settings, see the manual supplied with the wireless router or contact its manufacturer.
    As for a device already connected to the printer without using a wireless router, reconnect it via a wireless router.
  • Configuration, router functions, setup procedures and security settings of wireless routers vary depending on the system environment. For details, see the manual for your wireless router or contact its manufacturer.
  • For office use, consult your network administrator.
  • Note that if you connect to a network with no security protection, your personal information could be disclosed to a third party.

Wireless Direct

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.
  • When connecting the printer to a network, wireless direct and wired LAN connections cannot be used simultaneously.
  • 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.
  • 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, then configure settings again.
  • 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.

Connection Using a Wired Network

  • The printer cannot use wireless and wired connections simultaneously.
  • Wired LAN and wireless direct connections cannot be used simultaneously.
  • When using a router, connect the printer and computer to the LAN side (same network segment).
