Hi @Komatsukid


Welcome to the HP Support Community. I'd be happy to assist you with the blinking LED.


To better assist you - May I have the exact model name of the product? Refer to this document for steps to find the product details. Do not share any of your personal information such as serial, phone number, email ID, etc.


While you respond to that -


The battery might not charge if it is too warm, above 40º C (104º F). Disconnect the printer and let it cool down before you charge it or use it again.

1.) Turn off the printer, and then disconnect the USB cable.
2.) Let the printer cool for at least 15 minutes.
3.) Turn on the printer.


If the printer still does not turn on, the battery might not have enough power to turn on. Charge the printer for at least 30 minutes, disconnect it, and then turn on the printer.

1.) Connect the USB cable to the printer, and then connect the other end to a power source with at least 2 AMPs, such as a wall adapter or USB-capable power strip.

2.) Charge the printer for at least 30 minutes or until the Charging Indicator light turns green.
3.) Disconnect the USB cable from the printer and try turning on the printer.


If this does not fix the issue, please try the reset -


1.) Remove the paper cover.

2.) Locate the Reset button.
3.) With a paperclip or pin, press and hold the Reset button for 3 seconds.

4.) Place the paper cover back and try to turn on the printer.   


Hope this helps! Keep me posted.
