Print a network setup page from the printer to check the network settings.

Your wireless security settings are correct.

If you are not sure if your security information is correct, run the wireless setup again.

The printer and the computer are within the range of the wireless network.

The computer and printer are both connected to the same wireless network.

The printer is located away from obstacles or electronic devices that could interfere with the wireless signal.

Make sure the printer and wireless access point are not separated by poles, walls, or support columns containing
metal or concrete.

Many devices can interfere with the wireless signal, including baby monitors, motors, cordless phones, security
system cameras, other wireless networks, and some Bluetooth devices.

The computer is not connected to a VPN.

Test the USB port by connecting other devices to it. If you can successfully use other devices from the port, then the
port is working.

Your port may be working fine, but certain conflicts can occur with multiple USB devices. Try disconnecting
one of your other USB devices.

If the USB port on the computer is not working, then try using the other USB ports on the computer.
