Page Yield Up To 4000 Pages

This Compatible Extra High Capacity Epson 78XXL Black Ink Cartridge is quoted as doing up to 4000 pages before needing to be replaced.

The page yield is calculated by manufacturers using ISO/IEC 24711 standards, where they print set documents of 5% page coverage until the cartridge is empty. The standard means you can compare yields between cartridges and manufacturers.

Compatible Ink To Replace The Genuine Epson 78XXL Black

These Compatible Extra High Capacity Epson 78XXL Black Ink Cartridges are brand new cartridges made by a third party company as a money saving alternative to using the genuine Epson ink. They're fantastic inks that give you:

  • the same easy installation
  • print quality as good as the original Epson inks
  • a 12 month money back guarantee

This compatible black is manufactured to strict quality guidelines and standards, guaranteeing you get the best print quality in your Epson printer at a fraction of the cost.

Product Description

This is an extra high capacity compatible Epson 78XXL black ink cartridge. A compatible cartridge is a brand new cartridge made by a third party manufacturer, instead of the maker of your printer.

The compatible Epson 78XXL black cartridge can produce up to 4,000 black prints before it needs replacing. This makes it ideal for anyone who does large print runs or prints in high volumes.

The compatible 78XXL cartridge will fit in your printer and work exactly the same as the original! You can even use it along with any other compatible or original ink, no problem at all!

The 78XXL ink cartridge's are easily replaced when they run out! Open the front cover of the printer and push backwards on the cartridge you wish to remove, until you hear it click. It will then slide out of the printer. Remove any packaging from the new cartridge and push the new one into its space until you hear it click in. You can then shut the printers cover and away you go.

The 78XXL black cartridge is packaged in its own box so don't worry if you're not ready to use it straight away. You can store it for up to 6 months without its quality or performance being affected.

The compatible Epson 78XXL black cartridges are tried and tested, so we know they're top quality. Everything is covered by our 12-month quality assured guarantee anyway though!

Don't forget our delivery is fast & free and your compatible 78XXL black ink is covered by our 12-month guarantee.

My Epson printer used this compatible refill for a dozen copies and then did not recognise it. The same thing happened with the Yellow. Won't be ordering these again.

Good afternoon Billy,
So sorry to hear there have been recognition issues. We will email over some troubleshooting advice which may resolve the issue. If not we can arrange replacements or a refund for you.
I hope you have a nice day.
Kind Regards,

Great quality, great price, fast dispatch. Print quality matches the original WF5620 carts at a fraction of the cost. They install instantly with no problems so far.


A quality product from a company that has never failed to deliver over 15 years of buying from them.
This cartridge is another example of that excellence, with no installation or recognition issues, a good price & perfect performance in my Epson WF-5110 printer.


Bought as a spare so I haven't installed it as yet but I've no doubt it will be as good as usual. I've used these compatibles for some time now in my Epson WF5620 and have had no problems with them, the quality is just as good as the genuine ones. The printer itself, well that's another story...


Awesome product! Awesome price! Awesome service! Definitely recommended! :)


Very Good

Ask a question about this product

we have tried a compatible ink from another supplier for epson wfp5620 and had very low yield before getting error messages on screen and we were then referred to you tube and uncertainty whether they would replace

please tell me how you would deal with this and whether guarantee allows us to return in above circumstance

there was a month's delay before using the cartridge but this does not seem unreasonable - just ensuring constant supply

thank you


I am sorry to hear that you have had a bad experience, all our products are guaranteed for 12 months, if you were to have an issue just let us know and we can either resolve it with some suggested fixes or we can replace or refund. Easy as that.
