I had the same problen you did! Kept following the instructions and getting nowhere, the printer just turned off. Must have done it s dozen times or more.
But GOOD NEWS, keep trying, it did work in the end and now I have a working printer.
I held the ON/OFF button down, while holding the Stop/Reset botton down. Look under your finger untill the green LED is on. Then follow the rest of the instructions- press reset button twice, wait a few seconds, and then press it 4 times. (You hold the power button down the whole time.) Then let go of both buttons. Then turn off the printer, it took a while to respond to this. Turn it back on and off you go!!
I'm stoked!! Hope this helps.
