Hello there. I have a problem with my hp office jet pro 9015. It shows a message to align the head, to what I press yes, and then shows a blue screen with the error code B815835A and bluetooth-touchscreen buttons/power light blinking alternatively...
I searched on the web and says I need to perform a semi full reset, but it is imposible to do it using the back button method because once I press on it, it goes back to the head alignment screen... What should I do?
