Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

If the blue light is directly beside the Power button, then it flashing means, you need to Wait...

Are you following directions as to the setup?

Was the printer sold to you New, or Used ? it might be defective, if the flashing continues indefinitely, and if so, it would need to be packed up and returned.
