Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out, Anna.
Unfortunately this error indicates a hardware problem,
specifically, it is the result of a bad printhead (or the logic board that controls it).
It is not something that can be fixed, this is a "fatal" error on epson printers, as the printhead on these is not serviceable.
The printer would need to be replaced at this point, but it is a 2015 model and should still be under warranty, by calling(###) ###-####
