Frequently Asked Questions

Why does magenta matter so much for color-critical work?

Magenta does the heavy lifting in reds, pinks, purples, skin tones, and most brand colors. When magenta fades or runs unevenly, logos look washed out and photos turn oddly green-blue. A full, healthy magenta cartridge like this 9,000-page TN439M is what keeps client-facing documents looking the way they did on screen.

Will my flyers and brochures come out looking right?

That is exactly the workload this cartridge is built for. The TN439M is rated at 9,000 pages, and its toner is formulated to lay down smooth, even color across large filled areas like brochure backgrounds. At $37.48, your color cost works out to roughly 0.42 cents per page on standard test coverage.

If magenta runs low in the middle of a big print job, can I swap only that one?

Yes — pause the run, replace just the magenta, and resume. The other cartridges stay where they are, and there is no alignment or reset routine to worry about. The printer recognizes the fresh cartridge and recalibrates its level estimate on its own.

Which Brother models take the TN439M?

This magenta fits HL-L9310CDW, HL-L9310CDWT, HL-L9310CDWTT and MFC-L9570CDW. It is the highest-yield magenta made for that platform, and it can be installed alongside TN433 or TN436 cartridges in the other slots without any conflict.

How long will 9,000 pages of magenta last a marketing-heavy office?

It varies with coverage, but as a rough guide, a team printing a few hundred color pages a week is looking at many months from one cartridge. Heavy full-bleed pieces use far more toner per page than a memo with a small logo. Either way, this is the longest-lasting magenta available for these printers.

What if the color looks off or the cartridge underperforms?

Then we make it right: this cartridge carries a twelve-month warranty and can be returned free of charge any time within the first year. The plain-language terms live on our shipping and returns page. Support is staffed Monday to Friday, 9 AM to 5 PM CST, if you want to talk it through first.
