Frequently Asked Questions

Is this really the cheapest way to buy black toner for these printers?

Per cartridge and per page, yes. Five TN221BK cartridges in one pack work out to $12.47 each and about 0.50¢ per page — less than half the single-cartridge rate of roughly 1.09¢. Against five singles at $27.27 ($136.35), the $62.35 pack price saves $74.00 while delivering the identical cartridges. For the full shelf, see our Best Brother TN221 Toner Cartridges guide: the TN221BK black cartridge, the high-yield TN225 colors, the mixed sets and the DR221 drum units are compared side by side — including what each route costs per page when a single slot or the whole printer runs dry.

How many pages does the whole pack represent?

Each TN221BK is rated at 2,500 pages, so five of them carry about 12,500 pages of black printing. For a busy shared printer that is a serious runway — in many offices, the better part of a year's worth of black output in a single order.

Which printers do the cartridges in this pack fit?

They are the standard black for the Brother color laser/LED printers and all-in-ones in this family — the DCP-9020CDN, HL-3140CW, HL-3150CDN, HL-3170CDW, HL-3180CDW, MFC-9130CW and MFC-9330CDW — whose color slots use the TN225 line.

Who actually needs five black cartridges at once?

Shared workgroup printers, small print rooms, schools, and anyone whose machine chews through black far faster than color. If your printer's black warning shows up every few weeks, bulk is how you stop living order-to-order — and lock in the lowest unit price this family offers.

Will the last cartridge still be good when I finally open it?

Yes, under normal storage. Toner is dry powder in a sealed cartridge; kept away from heat and direct sunlight, the fifth cartridge performs like the first. It does not dry out or expire the way liquid ink cartridges can.

What backing comes with a pack this size?

Every cartridge carries a 1-year warranty, and returns within the first year are free under our shipping and returns policy. We ship from warehouses in IL, PA, GA, and CA, and support is available Monday–Friday, 9 AM–5 PM CST.

How do I keep a five-pack accounted for across more than one machine?

Keep a simple install log: each time a TN221BK goes into a printer, note the machine, the date and, if you can, the page counter, on the cartridge's box. With five cartridges and up to five printers from this family's list drawing on the same stock, memory alone blurs quickly. The log takes ten seconds per swap and pays for itself the first time someone asks which machine is eating toner fastest — the answer is in the boxes, not in opinions.

The last cartridge may sit for a year — how do I prove it when its turn comes?

Do not make its first job an important one. When a TN221BK that has waited a long time finally goes in, run a short everyday job first and read the third or fourth page: if a familiar document prints at full, even density, the cartridge has proved itself and can take anything. Keep the previous empty nearby for a few days as your comparison point. That small test costs two minutes and settles the question before a deadline settles it for you.

When is the reorder point in a pack this size?

When the last sealed cartridge goes into a printer. A five-pack's comfort is its depth — four spares behind the installed unit — but that depth hides the end until it arrives. Treat the final box as the reorder floor: the day it opens, place the next order at whatever pack size your log supports. Your install record will tell you whether five was right, or whether the office actually moves through black toner faster or slower than the pack assumed.

How does two-sided printing change the 12,500-page total?

It changes the sheet count, not the page count. The pack's 12,500 pages are printed sides: run everything two-sided and those pages land on roughly 6,250 sheets of paper. Paper savings are real and worth having, but the cartridges spend themselves by the side, so a duplex-heavy office should still expect about 2,500 sides from each TN221BK. When you compare the pack against your volume, count pages sent to the printer — that is the number the toner experiences.
