Restrictions

When connecting another device while a device (such as a computer) is already connected to the printer, connect it using the same connection method as the connected device.
If you connect using a different connection method, the connection to the device in use will be disabled.

Connection Using a Wired Network cannot be performed on printers that do not support a wired connection.

Connect via wireless router

  • You cannot establish a printer with wireless and wired connections at the same time.
  • 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.
  • Depending on your country or region, this printer does not support wireless networking standards using the 5 GHz band.
  • If your device is set to the "IEEE802.11n only" mode, TKIP cannot be used as a security protocol. Change the setting to something other than "IEEE802.11n only."
    The connection between your device and the wireless router will be temporarily disabled while the setting is changed. Do not proceed to the next screen of this guide until setup is complete.
  • 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.
  • 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.
  • 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, and then redo the settings.
  • Devices connected to the printer using Wireless Direct cannot communicate with each other.
  • Firmware updates for the printer may not be 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

  • You cannot establish a printer with wireless and wired connections at the same time.
  • When using a router, connect the printer and computer to the LAN side (same network segment).
