Yea it appears your graphtec is now either in Japanese or Chinese. I don't speak either. Both those screens are standard screens.
1st. Is for the direction of the roll load or sheet.
2nd. Is the main screen after you set the roll load.
I would say you had some sort of power surge and the plotter reset to factory defaults. Look up how to change the language and change it back to English. Should solve your problems. You could try resetting to default but if the default is Japanese you will end up back in the same spot.
