Check1
Make sure that the printer is turned on.
Check2
Are the network settings of the printer identical with those of the wireless
router?
Make sure that the network settings of the printer (e.g. wireless router name, SSID, network key, etc.) are
identical with those of the wireless 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.
Printing Out Network Setting Information
If the network settings of the printer are not identical with those of the wireless router, change the network
settings of the printer to match with those of the wireless router using IJ Network Tool.
Check3
Make sure that the printer is not placed far away from the wireless router.
The wireless router is located indoors within the effective range for wireless communication. Locate the printer
within 164 ft. / 50 m from the wireless router.
Check4
Make sure that there is no obstruction.
Wireless communication between different rooms or floors is generally poor. Adjust the location of the devices.
Check5
Make sure that there is no source of radio wave interference in your vicinity.
If a device (e.g. microwave oven) using the same frequency bandwidth as the wireless station is placed
nearby, the device may cause interference. Place the wireless station as far away from the interference source
as possible.
