hello, I am hoping someone can steer me in the right direction. I recently took the printhead out of my Epson r2880 and after cleaning and reinstalling it, I plugged in the printer and pushed the power button, the light went green for a second and then goes off. the only way to even get it to duplicate this is to unplug it. I do not know where to begin, could this be a circuit board problem, any advice will be greatly appreciated. frus trated
