This is an old question, but I have some background on this printer since I used to have one. The NX415 was one of the first generation printers Epson released with the dual chip setup using a wetness sensor that has continued to create headaches for end users and refillers. The external green chip you see is backed by a wetness sensor that detects the level of ink inside the carts. If you get it get to ~25% it’s permanently locked into read only mode and will need a chip replacement. This is an issue on the 88/69/68 and all of the carts that have been released since this series. The Epson black cart series no longer has the wetness sensor but the read only issue remains.

This is an old question, but I have some working information since I had one years ago. These NX415 printers are one of the first dual chip wetness sensor printers with the 88/69/68 series carts that don’t like to come out. These carts are a nightmare for refillers and end users who refill their own carts.
-
In many cases,these wetness sensor printers are also known to kill the chip if you remove the ink with a low ink indication and the carts never work again,especially once you hit the magic ~25% capacity mark I mentioned before. This is exactly why Epson doesn't recommend removal unless you intend to replace the cartridge - you're probably going to kill it if you don't know this is a major no no.

These carts are built in such a way where you have the primary chip (which has been used for years) and a wetness sensor behind it. Once the sensor goes dry at ~25%, the chip goes into permanent read only mode and the only way out being a new chip. The modern Epson black carts no longer use this wetness sensor but the read only lockout is still present.

The other gotcha with these modern Epson printers is the wetness sensor carts DO NOT LIKE to be removed, especially at the point the ink level is reported to be low (~25%) or empty. If you remove these carts before they go to 0%, they tend to be permanently killed and again, need a new chip much like if you refill a locked out cart. Epson even warns end users not to remove these things until you are going to replace it.

It sounds like you removed a low cartridge and replaced it not knowing about this problem that affects the modern Epson cartridges. The cartridge is probably ruined and no longer usable, so you probably need to replace it OR fit a new chip on if you're equipped to change it. Of course, it has to be one that Epson hasn't sued over to prevent importation. Thankfully the NX415 is a grey cart printer, so they aren’t using firmware to block 3rd party ink if you can’t afford OEM.

It sounds like you removed a low cartridge and replaced it not knowing about these problem that affects these newer Epson printers. I’m suspecting the cartridge is ruined and needs a new chip or a whole new cart as a replacement. Of course, it has to be one that Epson hasn't sued to block from being imported. The NX415 is a grey cart printer, so there are no firmware blocks that are “security” updates.

These printers are also known to kill the chip on these cartridges when you remove the ink from these printers the majority of the time. It's especially likely once you get to the ~25% mark, which is when the chip has the highest probability of being damaged.This is exactly why Epson doesn't recommend removal unless you intend to replace the cartridge - you're probably going to kill it if you don't know this is a major no no.

It sounds like you removed a low cartridge and replaced it, not knowing this is a grave mistake that is likely to ruin the chip on your cartridge. At this point, you ruined the cartridge and will either need to replace the whole cartridge (expensive) or find a chip that Epson hasn't sued over to prevent importation.

If you take a cartridge out that's too low, the cartridge will not be recognized once you put it in the printer again - it's permanently damaged. It sounds like you removed a empty cartridge and damaged the chip.

Epson was glad to market the crap out of this "feature" as a way to improve the reading accuracy, but neglected to mention they implemented it to kill cartridges and *really* stop refillers.
