The sections below describe the most common combinations of blinking lights, how to fix the issue, and how the issue is caused. NOTE: The light patterns included in this document are described as blinking or flashing lights. For the purpose of this document, "flashing" means the same as "blinking." Blinking lights Printer lights can can blink for more than one reason, so the solution can vary. These solutions need not be performed in a specific order, but solutions for the most common issues are presented first. Blinking lights are often accompanied by an error message on the computer screen, which might help determine the solution. Issue: Power light is blinking
