Frequently Asked Questions

Why does the second cartridge in this pack cost so much less?

Two singles bought separately come to $62.66, while this 2 pack is $44.16 — that puts each cartridge at $22.08 and saves you $18.50. The cartridges are identical; the saving comes from one shipment and one order instead of two. 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.

How many pages does the pack cover in total?

Each TN331 black is rated at 2,500 pages, so the pair gives you roughly 5,000 pages of black printing. Across the pack your toner cost drops to well under a cent per page compared with buying cartridges one at a time.

Is the spare cartridge going to deteriorate on the shelf?

Kept sealed in its bag, stored flat and away from heat and direct light, a toner cartridge waits patiently for a long time. Fit the first cartridge now and keep the second boxed until the printer asks for it.

When does a 2 pack make more sense than a single?

If your printer is a shared or business machine where an empty black cartridge stops everyone's work, having the replacement already in the cupboard removes the gap entirely. Light home printers that take months to finish a cartridge may be better served by a single.

Which printers do these cartridges fit?

Both cartridges in this pack fit the following Brother models: HL-L8250CDN, HL-L8350CDW, HL-L8350CDWT and MFC-L8600CDW

What warranty applies to a multi-pack?

Each cartridge carries the same 1-year warranty and 1-year free returns described on our shipping and returns page. The pack ships from IL, PA, GA or CA, and support is available 9 AM–5 PM CST.

We print a lot of two-sided documents — what does the 5,000-page total mean in sheets?

Yield is counted in printed sides, so each two-sided sheet spends two pages of the rating. Across this pack, 5,000 pages therefore come to roughly 2,500 duplexed sheets. The toner used per side stays the same, so duplexing remains a paper economy rather than a toner economy — but for planning purposes, a duplex-heavy office should read every cartridge in this pack as about 1,250 two-sided sheets.

Do copies on the MFC-L8600CDW come out of the black cartridge as well?

Yes. Copies are printed pages, and on the MFC-L8600CDW they draw on the same TN331BK as documents sent from a computer. An office that copies heavily will cycle through black noticeably faster than its computer print volume implies. When a black cartridge finishes earlier than expected, copy volume is the first explanation to check before wondering about the cartridge itself.

When is the right moment to order the next 2-pack?

When the spare goes in. The moment the second cartridge from this pack is fitted, the cupboard is empty behind it, and the freshly installed cartridge's 2,500 pages give you a comfortable window to reorder without urgency. Working that way, the pack renews itself as a cycle: one cartridge printing, one in reserve, and the next order placed the day the reserve is called into service.

What should I verify when the pack is delivered?

Check that both boxes carry the TN331BK code and arrive with their seals intact, before either is opened. The two cartridges are identical, so there is no wrong choice about which to fit first — but a thirty-second label check on delivery day confirms the pack in hand is the black 2-pack you ordered, and it is the easiest point at which any mix-up can be put right.
