If the printer is <1 year old phone Epson, they will visit on site and either repair or replace with a similar printer.
If not within warranty there are a host of ideas on this forum for head cleaning and dealing with failed ink supply, but I suspect it may be a hardware fault.
Occasionally 'masterly inactivity' may clear the trouble. Just leave it alone overnight! This will allow percolation of fresh ink along the pathways and displace the compressible air locks which result from running dry.
