Hi, I'm Sudipto. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
I don't know, what to suggest you, as you have tried the one any only solution for this problem, which is cleaning the ink from the printhead, but there are several other ways to clean the printhead, you can try them from the link below. If the problem persists then, unfortunately, the printhead is defective and as the printer is almost new, you have to send the printer for replacement.
Please remember, do not remove any screws if needed, because that can void the warranty.
Please contact Epson directly, so that the printer can be replaced quickly.
Please remember to give a positive rating, as that is the only way I am compensated for my time and effort.
