Frequently Asked Questions

Our MFC-9450 handles faxes, copies and color prints all day — which supply does that workload hit hardest?

Black, by a wide margin. Faxes arrive as black pages, copies are usually documents, and only deliberate color jobs touch the color cartridges. This TN115BK is sized for that reality: 5,000 pages at $44.92, about 0.90¢ a page, so the hardest-working supply is also the longest-lasting one in the machine.

Which printers does this cartridge fit?

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

Does receiving faxes wear out the color cartridges?

No. Incoming faxes print from the black cartridge alone. The TN115C, M and Y cartridges (4,000 pages each) are spent only when you print or copy in color, and each is replaced individually when its own level runs out.

How long between black changes in a fax-heavy office?

At 5,000 rated pages, even an office receiving a hundred fax pages a day gets roughly ten working weeks from one TN115BK. The standard TN110BK, at 2,500 pages, would halve that interval — on a machine that never stops, the high-yield is the calmer choice.

What should we do when colors finally run low as well?

Replace whichever color emptied; there is no set requirement. If black and colors converge on empty together — common after a long, busy stretch — the TN115 four-color set at $127.02 renews the whole machine in a single order.

What backing comes with it?

A one-year warranty plus one-year free returns, described on the shipping and returns page. It ships from IL, PA, GA or CA, and support is available 9 AM–5 PM CST.

How should a spare black be stored in a fax-heavy office?

Keep the TN115BK sealed in its bag, lying flat, in a cool dry place away from sunlight and heat, with one spare held near the MFC-9450 itself. A machine that receives faxes around the clock cannot wait on a delivery when the fitted cartridge ends, and a sealed spare stored this way is ready the moment it is needed.

Fax pages are coming through pale, but the cartridge has not reported empty — what buys us time?

Remove the TN115BK and rock it gently side to side five or six times to redistribute the toner still inside, then refit it. That usually brings back even, readable coverage for a good stretch of incoming pages. If the paleness returns quickly, the cartridge is truly finished — order the replacement that day rather than rocking it repeatedly.

Do two-sided copies and prints count double against the 5,000-page rating?

Each printed side is a page: a two-sided copy consumes two pages of the TN115BK's rating on one sheet. Duplex work therefore halves the paper bill, not the toner bill, and at 5,000 rated pages this cartridge still covers long stretches of fax, copy and print work before the office needs to think about it again.

How do we make sure the reorder is the high-yield black and not the standard one?

Read the code on the cartridge coming out: it should say TN115BK. The standard-yield sibling for this platform is the TN110BK at 2,500 pages, and ordering by machine name alone can land the wrong one. Matching the exact code keeps the MFC-9450 on the 5,000-page cartridge its changeover rhythm was built around.

About This TN115BK for the MFC-9450

A mixed-duty MFC is really a black-toner machine with color talents. This TN115BK respects that division of labor: 5,000 pages of fax, copy and document output at roughly 0.90¢ a page, while the colors wait patiently for the jobs that need them. It is the high-yield black built for the platform's busiest all-rounder — see the family on the Brother supplies page.
