Hi @SparksVona, 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 Connection

• Ensure your printer is connected to a Wi-Fi network: The blinking world button usually means the printer cannot find or connect to the Wi-Fi network. Make sure your printer is within range of your router.
• Check your Wi-Fi network: Ensure that your Wi-Fi network is working and other devices can connect to it (like a phone or computer).

Reboot the Printer

• Power cycle the printer: Turn off your printer, unplug it for about 30 seconds, then plug it back in and turn it on again. This often resolves minor connectivity glitches.

Check Router and Wi-Fi Settings

• Restart the router: Sometimes a simple router restart can fix connectivity problems. Turn off your router, wait 30 seconds, then turn it back on.
• Check for network interference: Ensure there’s no interference or overcrowding on your network. If possible, connect to a 2.4 GHz network instead of a 5 GHz one, as some printers have trouble connecting to the 5 GHz band.
• Ensure proper SSID settings: Verify that your router’s SSID (network name) is broadcasted and not hidden.

Reconnect Printer to Wi-Fi Network

• Use the Printer’s Control Panel:
  1. Press and hold the Wireless button on the printer until the light starts blinking (about 5 seconds).
  2. Then press the WPS button on your router within 2 minutes.
  3. Wait for the printer to connect. The world button should stop blinking and stay solid when successfully connected.
• Manually Connect to Wi-Fi:
  1. Press the Wireless button and the Cancel button together on the printer’s control panel.
  2. This will initiate the printer’s Wi-Fi setup mode. Follow the on-screen instructions to connect the printer to your Wi-Fi network.

Check Printer Software and Driver

• Update Printer Firmware: Sometimes the printer’s firmware can be outdated. Go to the HP website or use the HP Smart app to check for any firmware updates for your printer.
• Reinstall Printer Drivers: If you're trying to print from a computer, ensure that the latest printer drivers are installed. You can download the drivers from HP’s official website.

Check for a Printer Error

• Look for any error messages: If your printer is displaying an error message (such as "No Paper" or "Paper Jam"), resolve that issue, as it could be affecting the Wi-Fi connection.
• Clear any active print jobs: If there are stuck print jobs in the queue, cancel them and restart the printer.

Test with a Different Device

• Print a test page: Try printing from another device (like a phone or tablet using the HP Smart app) to verify whether the issue is with the printer or your original device.

Perform a Factory Reset (if necessary)

• If none of the above step's work, performing a factory reset on the printer might resolve the issue. Note: This will erase all current settings (including Wi-Fi network details).
  1. Turn on the printer.
  2. Press and hold the Wireless and Cancel buttons for about 10-15 seconds until the wireless light starts blinking.
  3. Wait for the printer to reset and reconfigure the network settings.

You can also refer to these helpful guides to resolve connection issues: Restore Wi-Fi setup, Use a Wireless Test report, HP printer is offline or unavailable and troubleshoot a Wi-Fi connection.
