Unfortunately this error indicates a hardware problem,
specifically, it is the result of a bad printhead (or the logic board that controls it).
The head is a "wear item" that fails with age/use. As this is a 2014 model printer, it is well into its 3 year service life, so this type of failure is not surprising.
This is considered a "fatal error" on epson printers, it cannot be repaired, as epson heads are not serviceable.
The printer would need to be replaced at this point. If by chance you are within the 12 month warranty still, Epson would cover that for you.
Even if beyond it, because this is a common failure, they will generally offer you a discount (about half price) on a replacement model, which will still cost much less than repairs would.
