Hp smart tank 559 power light blinking slowly tried everything

[Danny2023]

I have a hp smart tank 559 printer. It’s developed a problem where the power light flashes and a losing wheel spins on the display. I cannot press any buttons it does nothing. I’ve tried and tried with no luck on google and just wondering if anyone has had this problem? Also I don’t know if this is connected to the issue or not but the printer seems to do a very low pitch electrical hum. Not everyone can hear it but I can. If anyone has any suggestions please I’m at my wits end with this.

Hi @Danny2023,

Welcome to the HP Support Community

I understand you are facing an issue with your Hp smart tank 559 power light blinking slowly. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove the USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till the warm-up period finishes and the printer is idle

 all I get is this circle (looks like a number 7) but it’s just a circle going round and round and the power light blinks probably every 1 second on one second off. I’ve tried the method you suggested powering off and on and unplugging it etc but it’s just doing the same thing.
