@Stephen-9W, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Check Wi-Fi Network Credentials

Ensure the printer is trying to connect to the correct Wi-Fi network.

Double-check the Wi-Fi password to make sure it's entered correctly on the printer.

Confirm that the Wi-Fi network is operating on a 2.4 GHz band.

Restart the Printer

1. Turn off the printer.
2. Unplug the power cord from the back of the printer.
3. Press and hold the power button for 30 seconds.
4. Wait for 60 seconds and connect the power cord back in.
5. Turn on the printer.

Reset Printer Network Settings

Reset the printer's network settings to remove any stored Wi-Fi connections and reconfigure it.

• Turn off your printer.
• Press and hold the Wi-Fi button on the printer.
• While holding the Wi-Fi button, turn the printer back on.
• Keep holding the Wi-Fi button until the light blinks quickly, indicating that the network settings have been reset.

This clears any old Wi-Fi credentials, allowing you to reconfigure the printer for the new network.
