Been printing with Epson XP 15000 without problems right before installing firmware NW2017. We installed firmware (confirmed) and paid for and entered activation code. Tried to print a variety of items and printer looks like its printing, but all pages come out blank. We've unplugged printer, tried reflashing firmware (first printer error message we got was 031001, then some ink cart. maintenance errors), now we don't even get error messages. Looks like printer prints correctly with pages coming out all blank. We have relatively new authentic Epson ink cartridges in printer. Any help would be great as printer is now out of commission.
