Frequently Asked Questions

Who goes through three black cartridges before reordering makes sense?

Offices that print contracts, statements and reports all day. Three TN110BK cartridges at 2,500 pages each give you roughly 7,500 pages of black printing before you need to think about toner again. For a workgroup printer that never really cools down, that buffer turns toner from a weekly errand into a quarterly one.

How does the per-cartridge price move in the three-pack?

At $97.76 for three, each cartridge costs $32.59 — noticeably less per unit than the $35.67 you pay in the two-pack — and the cost per page falls to about 1.30 cents at rated yield. The more black you commit to up front, the cheaper every printed page gets.

Will three cartridges sit around long enough to go bad?

No. Toner is a dry powder, not a liquid ink, so sealed cartridges tolerate shelf time very well. Store them unopened, flat, in a cool dry place out of sunlight, and rotate stock so the oldest cartridge goes into the printer first. Offices typically work through three blacks in a few months anyway, well inside any reasonable storage window.

Which Brother printers take the cartridges in this pack?

Each unit is a TN110BK for the Brother color laser family built on TN110/TN115 cartridges: DCP-9040CN, DCP-9045CDN, HL-4040CDN, HL-4040CN, HL-4070CDW, MFC-9440CN and MFC-9450CDN. The same black slot also accepts the high-yield TN115BK, so this standard-yield three-pack and high-yield singles can be mixed over time on the same machine without any compatibility issue.

Do I have to install all three at once?

Not at all — the printer holds one black cartridge at a time. You install one, and the other two wait in their sealed packaging until the toner-low message appears. Replacement is a one-cartridge job that takes a couple of minutes, and the remaining spares keep their full 2,500-page yield untouched.

What if a cartridge in the pack underperforms?

Each cartridge carries a 1-year warranty, and returns are free for a year under our policy — the full wording is on our shipping & returns page. We ship from IL, PA, GA and CA warehouses, and our support team answers 9 AM – 5 PM CST if a cartridge ever prints light or streaky.

About This Brother TN110BK 3 Pack

Three compatible TN110BK black toner cartridges for Brother color laser printers, 2,500 pages each, for $97.76. The three-pack is sized for steady document volume: enough black to carry a small office through a season of printing at $32.59 per cartridge, with spares ready the moment the low-toner light comes on. Since the TN110 black is offered in multi-packs rather than as a single cartridge, this bundle is the practical way to stock the color that does most of the work.
