Epson SureColor SC-P8000 "Ink System Error 1482"

Hi,
for last 2 days some seconds after starting the printer I got this error on screen with recommendation to turn the print off and on again and if it doesn't work to call an epson service. I tried to google this particular problem to have an idea about the nature of the problem but without any success. Any Idea what this particular error code means?

Thanks,
Ali
