Product: HP DesignJet 800 PS 42
Operating System: Microsoft Windows 10 (64-bit)
I update the HP firmware on my HP DesignJet 800 PS (new firmware version A_04.02). Now the ON button flashed green and will not turn off the plotter. The LCD screen on the plotter provides an image of the plotter with a flashing X on the right. The plotter will do nothing not even turn off. I cannot navigate the menu on the plotter. I have moved the printer carriage to the center and this did nothing. What would be the next step?
