If you encounter an error code such as UU_400_EB000A9900 during the setup of your HP OfficeJet Pro 8120e, you can try the following steps to resolve the issue:

Power Cycle the Printer:

• Turn off the printer by pressing the power button.
• Unplug the power cord from the back of the printer.
• Wait for about 60 seconds.
• Plug the power cord back in and turn on the printer.

Check the Printer Connection:

• Make sure the printer is properly connected to a power source and your computer or network.
• If connecting wirelessly, ensure that your Wi-Fi network is functioning properly and the printer is within range.

Reset Network Settings:

• Go to the printer's control panel, navigate to settings, and reset the network settings.
• Reconnect the printer to your network by following the instructions on the control panel.

Check for Firmware Updates:

• Make sure your printer's firmware is up-to-date. Visit the HP support website to check for any available updates specific to your printer model.
