not necessarily faulty cartridge - had same problem went thru various cartridges some worked some didn't - in fact they weren't epson - so bought epson from office depot and that would not work, so not an issue of ink dried up - if yr printer is fairly old may be easier just to replace rather than waste time and money on trying to figure out problem

This model Epson printer may only let you use genuine Canon/Epson printer cartridges. If you try to refill these ink cartridges it will not work because the Epson cartridges have an embedded chip in the cartridge that detects the empty cartridge even though it has been refilled.

When replacing ink on the Epson Workforce 520, Ensure the cartridges have the correct/same number of gold contacts. Ive seen them with 7 and 9 gold square contacts and they were otherwise identical, and the ones with 9 contacts threw an "cartridge not recognized" error on the printer's dispay.

I'm assuming that you are probably using Non-Epson Ink Cartridges, because those are what normally cause that problem, with a printer not recognizing an installed ink cartridge. Unfortunately, there is no way to make your Epson Printer use or accept that Non-Epson Ink Cartridge, if it cannot actually recognize it. Its even possible that some Generic or Third-Party brands, may not always be recognized by the newer models of Epson Printers, because of the inexpensive [cheap] and or incompatable Electrical Chips that are mounted on the actual ink cartridge. Sometimes you will even get Error Messages up on your Monitors screen, telling you that you are actually using a Non-Epson Ink Cartridge, or that your printer cannot recognize the cartridge that you installed. Sometimes the Ink Level Indicator, on your Status Monitor, will not show an actual ink level, but may indicate a cartridge error or problem instead. Not all Generic or Third-Party ink & ink cartridges are made the same and none of them actually contain the right formulation of ink, for the Epson Printers [formula is patented by Epson Company]. Some are probably close and seem to be better than others, but some simply can clog-up or even damage the Printhead Assemblies on Epson Printers, or simply won't be accepted at all. Epson Ink Jet Printers are one of the few printers on the market that seem to have so many problems with non-manufactors inks, especially the newer models made in the last couple of years. Its because the Epson Printers use a completely different printhead inking system than most other brands of printers. Most, if not all of the other manufactors, use thermal or bubble jetprint heads and because the other brands use a totally different system, they don't seem to have as many problems using refilled inks or non-manufactor's ink cartridges. Printer manufacters do not make available their ink formulation and in most cases, the formulation is patented. Any difference in the ink formulation can actually cause clogging in the small printhead nozzles or damage other critical components. One individual printhead nozzle is so tiny, that it will not accept a human hair, so you can see why they can get clogged so easily, or even why the nozzles can be so easily damaged...Even if you were actually using a New-Epson Ink Cartridge, its always possible that you got a bad cartridge. At this point, the only thing I can suggest is that you try a different New-Epson Ink Cartridge, or at the very least, a different brand of Non-Epson Ink Cartridges and see if that helps.

Here's a tutorial on how to do it:
Solved Epson printer doesnt recognize Ink Cartridge

Epson Printers are sensitive in terms of Ink Cartridges.. The latest Epson Printers does not have ink reseter.. Ink reseter are already built-in on the ink cartridges.. The problem on this printer is when you have a cartridge on your printer, let say, 30% of the ink level, even though your ink is new, and you change it without using the right ink replacement method, it will recognize your ink as a 30% ink level. When your ink level drops to 0%, but you have remaining 70% of the ink, it does not recognize it anymore. The chip on the ink cartridge is already registered as an empty cartridge.

I understand that your NX415 can't recognize your ink, here's a tutorial which might help with this:
