Help and tips for Wi-Fi and connectivity (wireless model only)
If the software is unable to find your printer during setup, check the following conditions to resolve the issue.

Potential Issue/ Solution

Printer Wi-Fi setup mode timed out: If the Wireless light is not blinking blue, the printer might not be in Wi-Fi setup mode.
Restart setup mode:

1. Press and hold for 5 seconds. The Wi-Fi light will blink blue.
2. Wait for the printer to restart.
3. Open the HP Smart app and add the printer. If needed, swipe right/left on the top of the home screen to find the AddPrinter option.

Note: Only 2.4 GHz connection supported.

Computer or mobile device too far from the printer:

• Move your computer or mobile device closer to the printer. Your device might be out of range of the printer’s Wi-Fi signal.

The computer is connected to a Virtual Private Network (VPN) or remote work network:

• Disconnect from a VPN before installing HP Smart software. You can’t install apps from the Microsoft Store when connected to a VPN. Connect to the VPN again after finishing printer setup.

Note: Consider your location and the security of the Wi-Fi network before disconnecting from a VPN.

Wi-Fi turned off on computer (computer connected by Ethernet):

• If your computer is connected by Ethernet, turn on the computer’s Wi-Fi while setting up the printer. You don’t need to disconnect the Ethernet cable.

Bluetooth and location services are turned off on your mobile device:

• If setting up with a mobile device, turn on Bluetooth and location services. This helps the software find your network and printer.

Note: Your location is not being determined and no location information is being sent to HP as part of the setup process.
