Epson 812 DURABrite Ultra Ink High Capacity Yellow Cartridge (T812XL420-S) Works with Workforce Pro WF-7310 ,7820, 7840, EC-C7000

Epson recently rolled out yet another system update that causes the printer to not recognize the aftermarket brands without a workaround, so if you want to avoid the hassle and risk of that, this is the one to go with. And keep a spare at hand. The shelf-life is outstanding. I like that Epson separates the blue, cyan, and magenta into three different cartridges. I just hit a weird situation with another printer where the yellow ran out but the other two were fine and I had to throw the whole things out as it's all one cartridge. This set-up is more convenient, ecologically sound, and economical. I like the XL for this, because it lasts much longer than the standard size. I like the quality of the print, the fact it's not prone to smearing, and can produce bright, rich colors.

These are expensive and getting harder to find at a discount. OEM and as advertised. The last time I purchased I had to order through Epsom because everyone was out of stock.

got them a day or two late, but got them

I never use knock off ink. Epson ink is always excellent.

Works just as it should, easy to install.

I like Epson ink. Good color saturation. Does not smear like other inks. The cartridges seem to last OK. Just wish they were not so expensive!

This ink produces beautiful vibrant color prints.

Perfect fit for my Epson printer.
