What you'll get from this cartridge

Every cartridge is rated by how many pages it prints. Here's what that means for you.

MyInkToner compatible 0 pages

That's about 26,000 pages of letters, reports or documents – roughly 52 packs of printer paper.

All that works out at about 0.3p a page.

Page yield is tested to ISO/IEC standards and may vary with content, print settings and environment.

How page counts are measured

Every brand tests its cartridges the same way: on a typical page that's mostly white with a few lines of text, like a letter. That's known as 5% coverage.

Typical page
5%
Fully inked 100%

Everyday printing - letters, homework, recipes, tickets - is close to that, so you'll get about the page count shown. Pages packed with colour or pictures use more ink, so you'll get fewer.

1 page of text = 1 page

Letters, homework, reports and emails print at about 5% coverage.

So for everyday documents you'll get close to the full page count.

1 photo ≈ 5 pages

A standard 6×4 photo uses about five times the ink of a page of text.

Photos are coloured edge to edge, so you'll get fewer photos than pages of text.

Still Have Questions?

How long will delivery take?

Order before 4pm and we'll dispatch the same day, with free next business day delivery (tracked).

Could this damage my printer?

No. Our cartridges are built to match the original in every way — print quality, page yield, and reliability.

Will this void my printer's warranty?

No. By law, manufacturers can't void your printer's warranty just for using a third-party cartridge. If one of our cartridges ever causes an issue, we'll step in and cover the repair or replacement ourselves.

Why is my printer saying 'non-genuine cartridge'?

If you recently updated your printer's software and suddenly saw a "Non-Genuine Cartridge" or "Counterfeit Ink Detected" error message, you're not alone.

Printer manufacturers frequently push automatic firmware updates over Wi-Fi. While they claim these updates improve performance, their primary purpose is often to detect and block third-party smart chips — forcing you to buy their expensive brand-name ink.

Will your compatible ink work with my printer?

Yes. We constantly update our inventory with the latest generation smart chips, engineered to bypass these manufacturer blocks so your printer recognises our cartridges seamlessly.

If you've just installed our ink and encountered this warning, don't panic — in most cases your printer is simply trying to scare you. You can easily bypass it:

  1. Click "OK," "Continue," or "Yes" on your printer's screen or computer pop-up.
  2. If the message persists, take the cartridge out, gently wipe the chip with a lint-free cloth, and re-insert it.

How to stop your printer from blocking affordable ink

To prevent manufacturers from locking you out of affordable ink in future, we highly recommend disabling automatic firmware updates in your printer's settings menu.

What if it doesn't work or I'm not happy with it?

You're covered either way — every order comes with a 30-day return policy and a full 1 year warranty.
