Frequently Asked Questions
Our printed reds have gone orange and faces look sunburnt — is the magenta cartridge the reason?
Very often, yes. Magenta is the color that builds reds, pinks and skin tones, and as the TN439M runs down those are the first things to deform: reds slide towards orange because yellow starts dominating the mix, skin takes on a harsh yellow-red cast, and purples thin out. If the machine also reports the magenta supply as low, the two facts together are diagnostic — fit a fresh TN439M before you start adjusting software color settings, because no profile tweak can replace pigment that is not there.
What does a page printed with this cartridge cost?
The TN439M is rated at 9,000 pages and priced here at $241.72, which is roughly 2.7 cents for every rated page and $96.69 less than the $338.41 list price. That per-page figure assumes standard test coverage. A marketing team printing full-color sell sheets will land well above test coverage and should budget on fewer pages per cartridge; a team printing text documents with a colored logo will land close to the rating. The honest way to read any yield figure is as a comparison between cartridges, not a promise about your own pile of prints.
Why do presentation decks and photo runs eat through magenta so quickly?
Because saturated color is magenta's job. Backgrounds, gradients, brand blocks, photographic skin and product shots all draw heavily on it, and a single full-page image can use as much color toner as dozens of plain letters. Offices that print their own brochures and decks in-house are exactly the offices these flagship machines — and this 9,000-page TN439M — are built for: the ultra capacity exists so that a long print run is not interrupted halfway by a color change.
Which printers take the TN439M?
Our compatibility data lists four models for this magenta: the HL-L9310CDW, HL-L9310CDWT and HL-L9310CDWTT printers and the MFC-L9570CDW all-in-one — Brother's top-end color laser platform. The TN439M is the ultra high-yield magenta for those machines, rated to match the other TN439 colors page for page so the set depletes in a predictable rhythm.
Does the whole set of colors need changing when the magenta runs out?
No — each cartridge is monitored and replaced independently, and swapping in a fresh TN439M does not disturb the cyan, yellow or black still in the machine. Printing can continue with the other colors at whatever level they have reached. The only reason to change several at once is convenience when two or three are all reporting low in the same week.
How is this cartridge covered if something is wrong with it?
It is a genuine Brother product, so the warranty behind it is Brother's manufacturer warranty, and our own returns window is 30 days in all cases — the details live on our shipping and returns page. Report a damaged or faulty cartridge to support, Monday to Friday between 9 AM and 5 PM CST, and keep its packaging until the first prints have come out clean.
