Is the printer connected to the wireless router?
Check2
Use the icon on the LCD to check the connection status between the printer and wireless router. If the
icon is not displayed, Wi-Fi is disabled. Turn on wireless communication on the printer.
Make sure the printer and wireless router network settings match.
Check3
Make sure the network settings of the printer (e.g. network name (SSID) or network key (password), etc.) are
identical with those of the wireless router.
Communication with a wireless router must be tuned to either the 2.4 GHz or 5 GHz frequency band. The
network name (SSID) of the 2.4 GHz frequency band and the network name (SSID) of the 5 GHz frequency
band cannot be used in combination.
Check the network name (SSID) set for the printer, and match it with the network name (SSID) of the correct
frequency band of the Wi-Fi router.
To check the settings of the wireless router, refer to the instruction manual provided with it or contact its
manufacturer.
To check the current network settings of the printer, print out the network setting information of the printer.
Printing Network Settings
Make sure the printer is not placed too far away from the wireless router.
Check4
If the distance between the printer and wireless router is too far, wireless communication becomes poor. Place
the printer and wireless router close to each other.
Make sure wireless signal is strong. Monitor signal status and move printer
Check5
and wireless router as necessary.
Place the printer and wireless router where there are no obstacles between them. Wireless communication
between different rooms or floors is generally poor. Wireless communication can be impeded by building
materials containing metal or concrete. If the printer cannot communicate with the computer over a Wi-Fi due
to a wall, place the printer and the computer in the same room.
In addition, if a device like a microwave oven that emits radio waves of the same frequency bandwidth as a
wireless router is nearby, it may cause interference. Place the wireless router as far away from interference
sources as possible.
Check the signal strength on the LCD.
Indication of LCD
Make sure of the Wi-Fi channel numbers used for your computer.
Check6
You need to have the same Wi-Fi channel number that you are using for the wireless router as your computer.
It is normally set in the way that you can use all the Wi-Fi channels. However, when the channels that you are
using are restricted, the Wi-Fi channels do not match.
See the instruction manual provided with your computer and check the Wi-Fi channel number available for
your computer.
Make sure channel set on wireless router is a usable channel as confirmed in
Check7
the previous check.
