What Gary stated is a good list of options and may work.
Unfortunately, since the chip is was can be damaged upon being put into the plastic, it's not something that anyone can tell if it may be damaged until you put it into the printer. If you take it out and reinstall, maybe it was a hiccup with the printer reading it at first. I've had some customers attempt this option many many times with no luck and a few others that did it 1-2 times and it worked. It's a gamble attempt basically.
Turning the printer off and back on again may reset the chip reader in the printer and it works; or it still doesn't. Usually this case is from a defective chip.
Most places will do an exchange for it within their return policy timeframe, or you can go to Epson direct and they usually have a 1-year warranty from purchase date.
If you bought through another person (like eBay or possibly Amazon), it may not be easy to get it replaced since the seller may not have this ability and Epson may not replace it from an unauthorized (re)seller.
Wish you luck and hope it's a printer hiccup and it reads!
