Easy Understanding Network Connections

Connect the printer and devices (e.g. computer/smartphone/tablet) using a wireless router.

If you have a wireless router, we recommend you use one for wireless connection.

• Connection methods vary depending on the wireless router type.
• You can change network settings such as the network name (SSID) and security protocol on the printer.
• When the connection between a device and a wireless router is completed and (Wi-Fi icon) is displayed in the device's screen, you can connect the device to the printer using the wireless router.

Connect the printer and devices (e.g. computer/smartphone/tablet) without using a wireless router.

• While you are using the printer with Wireless Direct, Internet connection from the printer becomes unavailable. In that case, web services for the printer cannot be used.
• If you connect a device connected to the Internet via a wireless router to the printer that is in the Wireless Direct, the 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. Transmission fees for connecting to the Internet using a mobile data connection apply.
• In the Wireless Direct, 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 you do not use and configure settings again.
• Network settings such as the network name (SSID) and security protocol are specified automatically.

• Connecting with Wireless Direct

Connect the printer and hub/router using a LAN cable. To make a wired connection on a model that supports wired connection, prepare a LAN cable.

Note
