Frequently Asked Questions

How should I rotate two cartridges so neither is wasted?

Treat the pack as a small queue: fit one cartridge, keep the second sealed in its box with the purchase date noted on it, and install it only when the first is fully spent. Toner does not need to be used in any special order beyond oldest first, and a sealed cartridge stored cool, flat and out of sunlight keeps its full rated life.

What does this pack cost per cartridge?

The 2 pack is $44.16, which works out to $22.08 per TN331 black cartridge — $18.50 less overall than ordering two singles at $31.33 each. Each cartridge is rated at 2,500 pages, so the pack covers roughly 5,000 pages of black printing. For the three tiers of this platform priced side by side — TN331, TN336 and TN339 — and the per-page math that separates two tiers sharing one shelf price, see our Best Brother TN331 Toner Cartridges guide.

Where is the best place to store the spare?

A cupboard near the printer, away from radiators, windows and damp, is ideal. Leave the cartridge in its protective bag until fitting day; opening it early only exposes the drum surface to light for no benefit.

Can I split the pack between two printers?

Yes, as long as both machines take the TN331 — one cartridge per printer works perfectly well and the pack pricing still beats two separate single orders. Check both model names against the compatibility list below before ordering.

Which printers are compatible with these cartridges?

These TN331 black cartridges fit the Brother models listed here: DCP-L8400, DCP-L8400CDN, DCP-L8450, DCP-L8450CDN, HL-L8250, HL-L8250CDN, HL-L8350, HL-L8350CDW, HL-L8350CDWT, MFC-L8600, MFC-L8600CDW, MFC-L8650, MFC-L8650CDW, MFC-L8850, MFC-L8850CDW, HL-L9200CDW and HL-L9200CDWT

What if one cartridge from the pack has a problem?

Every cartridge is individually covered by a 1-year warranty with 1-year free returns — full details are on our shipping and returns page. Orders ship from our IL, PA, GA and CA warehouses, and support answers 9 AM–5 PM CST.

How far does the pack go if most of our printing is two-sided?

Count sides, not sheets. Each TN331BK in the pack is rated at 2,500 pages, and a duplexed document spends a page of that rating on every printed face — so the pair's roughly 5,000 pages become about 2,500 two-sided sheets when both faces print. Single-sided work, the same pack runs to the full 5,000 sheets.

How should I judge the first cartridge out of the pack?

On its third or fourth page. A freshly fitted TN331BK settles over the first few sheets, so give it a familiar document a few times and judge the settled output — crisp text, even fills — rather than the very first page. A good first cartridge is the pack's proof; note how it does before the second one is needed months later.

Is it worth writing anything on the second cartridge's box?

The fitting date of the first one. When the second TN331BK finally goes in, that note tells you exactly how long 2,500 pages lasted in your real workflow, and the date you fit the second starts the same clock for judging the pack as a whole. Two dates turn a simple 2 pack into your most accurate reorder forecast.

What do the two empties tell us at the end of the pack?

Read together, they are your consumption record: two known quantities of black, fitted and finished on dates you noted, across machines whose names you know. That is a firmer basis for choosing between another 2 pack and a larger bundle than any rated figure. Box each empty as it comes out so residue stays contained until both go to recycling together.
