Restrictions

When connecting another device while a device (such as a smartphone) 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 network devices vary depending on the system environment. For details, see the manual for your network device or contact its manufacturer.

• Check if your device supports IEEE802.11n (2.4 GHz), IEEE802.11g or IEEE802.11b.

• If your device is set to the "IEEE802.11n only" mode, WEP or TKIP cannot be used as a security protocol. Change the security protocol for your device to something other than WEP and TKIP or 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.

• 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.

Direct Connection

Important

• If a device is connected to the Internet via a wireless router, and you then connect it to a printer in

Direct Connection 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 Direct Connection, 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.

• You cannot connect to a wireless router and a printer in Direct Connection mode at the same time. If you have a wireless router, it is recommended that you use the wireless router to connect to the printer.

• To prevent automatic connection to the printer in Direct Connection 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 checking or changing wireless router settings, see the wireless router manual or contact its manufacturer.

• If you connect a device and the printer using Direct Connection, Internet connection may become unavailable depending on your environment. In that case, web services for the printer cannot be used.

53

• In Direct Connection 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 Direct Connection cannot communicate with each other.

• Firmware updates for the printer are not available while using Direct Connection.

• 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 a device to the LAN side (same network segment).
