I purchased the activation key and ran the firmware for my Epson WF-7210. But I am not getting a "finished" code on my printer screen. I am getting the following.
SUM D08B/67E6
VER SA12J4/10.43
And the error light just flashes.
I press OK and the printer turned off, so i continued the instruction, but they doesn't work.
I've the error 0000043 and i can't use the printer
