Frequently Asked Questions

This MFC-9440 is our first color laser — is a high-yield black cartridge a sensible starting point?

Yes, and it simplifies your first year of ownership. The TN115BK gives you 5,000 pages at $44.92 — about 0.90¢ per page — so black, the cartridge every new owner uses most, needs the least babysitting while you learn the machine. You will get comfortable with color management long before this black asks to be changed.

What printers is this cartridge for?

It fits the TN115 platform: DCP-9040CN, DCP-9045CDN, HL-4040CDN, HL-4040CN, HL-4070CDW, MFC-9440CN and MFC-9450CDN

How do the four cartridges work together in a color all-in-one?

Think of them as four separate tanks. Black handles text, faxes and copies; cyan, magenta and yellow (4,000 pages each) combine for color. Each tank empties on its own schedule and is replaced on its own — there is no drum cartridge to buy on this platform, since the drum unit is part of the printer itself, and this page sells the black toner only.

What is the difference between TN115 and TN110 that I keep seeing?

TN110 is the standard-yield family for these printers (2,500 pages black, 1,500 per color); TN115 is the high-yield family (5,000 black, 4,000 per color). Both fit your MFC-9440. High yield costs less per page and interrupts less often, which is why most owners settle on it.

When we eventually need colors, what is the easy route?

Replace each color individually as it empties, or — when several supplies run low around the same time — order the TN115 four-color set ($127.02), which bundles this black with all three colors for less than the separate singles.

What if something goes wrong with the cartridge?

It carries a one-year warranty and one-year free returns, laid out on the shipping and returns page. Orders ship from IL, PA, GA or CA, and support keeps 9 AM–5 PM CST hours.

Our MFC-9440 sits in a corner and faxes arrive all day — should we plan for that?

Yes. As the existing answers note, black handles text, faxes and copies on this machine, and received faxes are the quietest load of all: nobody watches those pages print, yet every one of them draws on the TN115BK. Offices that add expected fax volume to their print volume find the 5,000-page rating holds up far better as a forecast.

Text on our pages is getting faint — is the cartridge finished?

Not necessarily at the first sign of fading. When the TN115BK runs low, output typically fades evenly across the page. Removing the cartridge and rocking it gently side to side redistributes the remaining powder and often restores solid text for a good while longer. Sharp streaks or repeating marks that survive a cartridge swap point at the machine instead, since this platform's drum is built into the printer itself.

How do we make sure we order the right black cartridge next time?

Read the code on the cartridge you pull out. This machine's high-yield black is the TN115BK — the BK suffix marks it as black, while TN115C, TN115M and TN115Y are the cyan, magenta and yellow slots. The standard-yield TN110BK also fits, but ordering it by mistake halves your pages to 2,500, so a ten-second label check before reordering protects the longer runway.

Can we keep a spare TN115BK on hand from day one?

Certainly, and new owners often do. Keep it sealed, flat, in a cool dry place out of direct sunlight. Toner powder does not dry out or spoil the way liquid ink can, so the spare waits at full capacity until the installed cartridge gives out — turning your first replacement into a two-minute swap instead of a shopping trip.

About This TN115BK for the MFC-9440

Every color-laser owner learns the same first lesson: black does the everyday work. Starting with the 5,000-page TN115BK at roughly 0.90¢ a page lets an MFC-9440 settle into your office without an early supply errand, and leaves you free to discover the color side at your own pace. The rest of the family's cartridges are gathered under Brother toner.
