I purchased the Epson 69 black cartridge for my Epson Stylus All-In-One NX415 Printer. It states on the printer, "Replace only the color you need with individual cartridges." This is rhetoric to confuse the buyer. It does not mean that buying the black cartridge when the others are depleted will work. Buying this cartridge on its own for this printer is useless. The printer will not accept it without the other cartridges. Do not purchase this if you only need a black cartridge; the printer will NOT work without all of the ink cartridges. Hope this helps someone.
