The most likely cause is the printer's Wi-Fi setup mode has timed out. Restart it.
- Swipe down on the printer's display to open the Dashboard.
- Tap the settings icon ( > ), then tap Network Setup > Restore Network Settings. Tap Yes when prompted.
- Wait one full minute. Close the HP Smart app completely, reopen it, and try the setup again.
If that didn't work:
- Your computer or phone is too far from the printer. Move your device closer.
- If you're using a computer with a VPN (Virtual Private Network), disconnect from the VPN before installing or running HP Smart. Reconnect after setup is complete.
- If setting up with a phone, ensure Bluetooth and Location Services are turned on.
Heads up: If your printer has a label covering the USB port, you must set it up initially with HP Smart and an internet connection. USB is for printing only after setup.
