Hi @Mobusiness,

Welcome to the HP Support Community. 

I'd be happy to help you! 

I understand that you are facing issues with blinking lights. 

Here are a few details. 

Power light blinks fast

• The Power light blinks fast when the ink cartridge door is open, or the printer is in an error state.
• 
• If an error message displays on the computer or mobile device, follow any steps to resolve the issue.
• If the ink cartridge door is open, close it.
• If the ink cartridge door is closed, try printing a document to generate a message.

Wireless light blinks, Wireless Attention icon is on, and signal bars are cycling

• The Wireless light blinks, the Wireless Attention icon is on, and the signal bars are cycling when the wireless connection is on, but the printer cannot find a wireless signal.
• 
• Wait for the printer to establish a connection. If the Wireless light still blinks, check for network issues. Go to Troubleshoot a Wi-Fi connection to an HP printer for more information.
