My Epson Scanner Giving alot of Errors

Hello people, I have an Epson V600 scanner that is rated at 6400×9600 dpi. Whenever I try to scan, it only lets me scan a maximum of 2400 dpi and if I choose a higher dpi, an error message appears saying the file s too big. I need to know if there is a limit on the file size and if so, is there a way to increase it to a higher dpi? Thank you in advance.
