Printing Network Settings

Network Status	What to Do
Connected normally. If you are unable to print, see 1 on What to Do.	If you are unable to print, check the items below: whether the computer is connected to Wi-Fi whether the firewall of your security software is enabled whether a privacy separator, SSID separator, or Network separation function is enabled on your wireless router If one of the above is enabled, disable it before setup. whether the network name (SSID) of the printer matches that of the router to connect To change the network connection method (wired/wireless), change it on the printer's network setting screen.
When Wi-Fi is disabled on the printer	Perform printer setup following the instructions of the manual.
When wired LAN connection is disabled	Make sure the printer is connected to the router with the LAN cable. If the LAN cable is loose, connect the cable properly. If the LAN cable is connected to the WAN side of the router, connect the cable to the LAN side of the router. Make sure the network devices (e.g. hub or router) are turned on.
When an IP address is not assigned	If you specify the printer's IP address automatically, enable DHCP on the router. If you specify the printer's IP address manually, the address is disabled because it is out of the valid range. You specified (0.0.0.0) as the IP address, for example. Specify the valid IP address.
When the default gateway is not specified	Check the items below to communicate by hopping routers (e.g. using a cloud application). Make sure the device specified as the default gateway is turned on. Specify the default gateway address correctly.
When the printer cannot connect to the specified network	Check the status of the printer, network devices (e.g. wireless router), or smartphone/tablet. If they are turned off, turn them on. Make sure wireless signal is strong. Monitor signal status and move the printer and wireless router as necessary. The security key specified for the wireless router may not match that you entered. The security key is case-sensitive. Enter the correct security key.
When the wireless signal is weak	Make sure the printer is not placed too far away from the wireless router. Monitor signal status and move the printer and wireless router as necessary.
When the number of connected clients has reached the upper limit	The number of mobile devices that can be connected directly with initial settings is 1 device. If a fixed SSID and network key are set, up to 5 devices can be connected at the same time.
When the signal to noise ratio (S/N ratio) is low	There is a lot of noise from other devices. Move the printer apart from other devices.
When a link local address is assigned	Perform printer setup again. The security key specified for the wireless router may not match that you entered. The security key is case-sensitive. Enter the correct security key.
When the specified network name (SSID) is still the default value	The network name (SSID) is not specified. Enter the network name (SSID) specified for the destination.
