Real, tested page yield

Straight from this cartridge's spec sheet.

MyInkToner compatible 0 pages

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

What does 5% coverage mean?

Page yield is measured using the industry-standard 5% coverage page - not a fully inked page.

Standard
5%
Solid page 100%

Most of the page stays blank at 5% coverage. A fully inked page uses far more ink, so you'd get far fewer pages from the same cartridge.

≈6 essays

from a 1,000-page cartridge (about 1,500 words each)

Text uses small type and lots of white space, so coverage is usually around 5%.

≈300 photos

from a 1,000-page cartridge (standard 4×6 prints)

Photos use more colour and full-page coverage, so you'll get fewer than with text documents.

Won't damage your printer — guaranteed

We know some people worry a budget cartridge could harm their printer. Ours won't. In the unlikely event it does, we'll repair or replace your printer free of charge — no matter how old it is.

Your printer's warranty stays protected

By law, using a third-party cartridge can't void your printer's manufacturer warranty. If anything ever goes wrong because of one of our cartridges, we'll step in, cover the cost, and handle repairs or a replacement ourselves.

Bottom line: there's zero risk in switching.

    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.
