Important Make sure the following four items first. - If the security settings on the wireless router are enabled, to disable the settings may solve the problem. · Privacy Separator/SSID Separator/Network Separation Function -If the printer is connected to the 2.4 GHz SSID, connect your computer or smartphone to the 2.4 GHz SSID, or connect it to the 5 GHz SSID if the printer is connected to the 5 GHz SSID, then this may improve the condition. · Cannot Print/Set up/Find the Printer Even Though it is Connected to the Wireless Router and the Network - To disable Band Steering function* of wireless router may solve the problem. - If the same SSIDs are assigned for 2.4 GHz and 5 GHz, to assign different SSIDs may solve the problem.
· Frequency band such as 5 GHz or 2.4 GHz for wireless connection
* Band Steering function: Band Steering monitors a Wi-Fi network and automatically assigns devices to their optimal frequency band within 2.4 GHz or 5 GHz frequency bands depending on the situation.
In the following cases, set up the printer again.
·When you buy a new computer or wireless router
·When you change the settings on your wireless router
·When the connection method (Wi-Fi / USB) of the printer is changed
Step 1 : Check Basic Items for Network.
Check 1 Check power status.
Check your printer and the network device (wireless router, etc.) are turned on.
If you are in the process of setting up, interrupt it and check if the wireless router (modem) is turned on and then check if the printer is turned on.
1. Check if network device such as router is turned on.
If network devices are not turned on, turn on the power. If the network devices are on, turn them off and on again.
It may take a while for the network device to become ready for use once they are turned on.
Proceed once the network device such as router is ready for use.
2. Check if printer is turned on.
If printer is not turned on, turn on the power. If the printer is on, turn it off and on again.
Proceed once you complete checking the power status above.
Check 2 Check PC network connection.
If your computer and network devices (wireless router, etc.) are fully configured, your computer is ready to connect to the network.
1. Check the settings of the network device (wireless router, etc.).
Connect to the Internet and see if you can browse any web page. If you cannot view web pages on your computer, check wireless router network connection settings, such as IP address filtering, MAC address filtering, and DHCP function.
To check the network name (SSID) of the wireless router the printer is connected to, print the network settings.
· Printing Printer’s Info (BT/Serial No./ Wi-Fi SSID/ IP Address/ Wi-Fi Sharing QR Code)
Note
· Depending on the wireless router, note that different network name (SSID) is assigned for a bandwidth (2.4 GHz or 5 GHz) or its usage (for PC or game machine), using alphanumeric characters at the end of network name (SSID). · For more on checking the settings of the wireless router, refer to the instruction manual supplied with the wireless router or contact the manufacturer.
·If you use an encryption key, specify it for the network name (SSID) you are using. For details, see Setting an Encryption Key.
2. Check PC network connection.
For the procedures, refer to the instruction manual supplied with the computer, or contact the manufacturer.
Once you complete setting up the wireless router and your computer, configure the settings on your computer in order to view web pages, using the information of the wireless router.
Proceed once you complete checking the network connection above.
Check 3 Check printer's network settings.
Make sure that the Indicator keeps Purple/Blue steady on.
If green light is steady on, or if the blue and green lights are alternating, the wireless router and the printer are not connected. (Indicator details are as follows)
Reconsider the location of the wireless router and the printer in the next check.
Check 4 Check location of wireless router.
Make sure the printer is not placed too far away from the wireless router.
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.
Step 2 If Problem is Still Not Solved.
Check 1 Make sure security software's firewall is off.
If your security software's firewall is on, a message may appear warning you that JADENS_Printer_Driver is attempting to access the network. If this warning message appears, set security software to always allow access.
If you are using any programs that switch between network environments, check their settings.
Check 2 Wi-Fi Name may cause connection issues.
For best compatibility, we recommend using a simple Wi-Fi name (letters and numbers only).
Check 3 Solve network troubles with the printer's diagnostic functions.
