Hi, I'm Sadique. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
Remove the black cartridge and inspect the chip contacts (in printer). Epson printers use a series of thin gold plated wire contacts that the cartridge chip slides and presses against - when cartridge is installed. These contacts can corrode, or stick to the chip, particularly if they ever had any ink contamination. The wires can sometimes bend, or even get pulled out - with cartridge, when it is removed.
Tell me what you observe.
