When a single one cartridge in a set fails :(
Style: Ink, Style: Ink
This for use in my oldish Epson WF-7840 model, which is an ink guzzler; its decent print quality and large paper format notwithstanding. For work projects and good color on laser & gloss papers, this is the only good ink choice on this model. Well, that is, IF you get all ink cartridges in a set working.
Therefore, given its price, it is frustrating that, when a brand new single cartridge (of a set) fails, you can be left with few good choices. Along the years, this has happened to me twice...plus today, just one, of a pricey Epson set, failed. When I've bought from a local store, they have had no problem helping with this issue in the past.. I am sure that Amazon & Epson will make it right also.
YET, I do have to send back the whole set, even for a single cartridge replacement, which they DO HAVE AS A SEPARATE item. It is a bit of a drag because I need the printer working now and this magenta ink cartridge is all I needed to work at this time.
How about dedicating some of Amazon's awesome IT & AI power to distinguish and better respond to this kind of situation? After all, Artificial Intelligence can sort this kind of thing in just a bit or two.

The EPSON 812 DURABrite Ultra Ink is excellent! It fit perfectly in my printer with no problems at all. The print quality looks sharp, clear, and professional colors come out bright and crisp every time. The ink lasts a long time, so it’s definitely worth the price. I’m very happy with it and will definitely buy again. Great product from Epson!
