Hello.
Please help.
I already did everything you said (@jabzi), (https://h30434.www3.hp.com/t5/Printers-Knowledge-Base/Error-79-on-HP-Color-LaserJet-Pro-M280-M281-Multifunction/ta-p/7864853) by my printer keeps looping: "ready state" for few seconds and then "79 Error: Please turn off then on", again and again.
I also downloaded a firmware. I tried to install it in my printer but the printer never gets in "ready state" for more than 3 seconds.
What can I do?
I have several days trying to fix it. I am loosing my mind.
Thank you very much
