HP Laserjet Pro MFP M125a same time blinking HP text, ready and alarm lights

[JaneDo]

Hello, 

I got this oldish printer but it not work with my laptop. Something happened before my time, this error had appeared suddenly with HP Pavillion xxxx. 

At once the printer is powered on appears same time blinking green HP-text, green ready and  yellow alarm lights. 

I've done following:

• Disconnected the power cable from the printer while the printer is still ON.
• Disconnected other cables if connected the printer.
• Pressed and holded the printer’s power button for 15 seconds.
• Reconnected the power cable to print and the printer did power ON by itself

But problem still continues. 

The printer has been under-used, so it would be great if it could still work - could it? 

Thanks in advance if find help with this problem!

Here you will see a guide on the light codes for your printer model and some actions you can take to resolve them.  Look through the list and see if any match what you are seeing on teh printer.

I would guess you are referring to a blinking ready and attention light.  That suggests the printer is initializing and attempting to boot up.  If the printer cannot boot then it may have suffered from a firmware failure or power failure.  In either case it may require a formatter board replacement to fix the issue.  Since your printer is old it likely doesnt have HP warranty so you will need to get a quote from a local printer repair shop.

The only other things you can do would be to try plugging the printer directly into the wall Power outlet.  Try plugging the printer into a few outlets if you have them and see if it can properly boot.  If not then its time to get a repair quote.
