Frequently Asked Questions

Why does the second cartridge in this 2-pack effectively cost only $7.49?

Because that is how this family's pricing ladder is built. A single 331-0778 costs $25.98; this 2-pack costs $33.47 — just $7.49 more for a second, identical cartridge. Put against buying two singles at $51.96, the pack saves you $18.49. Each additional cartridge in this range steps up by roughly $7.49 rather than another $25.98, so the per-cartridge price falls steeply: $16.74 each here, against $25.98 bought one at a time. We quote the ladder exactly as it stands rather than rounding it into a vaguer "bulk discount".

What does the 2-pack bring the cost per page down to?

Two cartridges rated at 2,000 pages each give you 4,000 pages for $33.47, which works out to about 0.84 cents per page — down from roughly 1.30 cents when the same cartridge is bought singly. That is a real, measurable drop for adding one spare to the order, and it is why the single cartridge is best thought of as the convenience option in this family.

Who is a 2-pack the right size for?

Anyone running one Dell 1250-series printer — a 1250c, 1350cnw, 1355cnw, C1760nw or a sibling — at steady small-office volume. One cartridge goes in the machine, one sits sealed on the shelf, and the printer never waits on a courier when the black runs dry mid-job. If your 331-0778 lasts you the better part of a year, the spare simply waits with it; if you burn through one in a couple of months, the 2-pack keeps the rhythm without tying up much cash.

How long will 4,000 pages of black toner last?

At a typical small-office rate of 200 black pages a month, the pair covers around 20 months; at 500 pages a month, about eight months. Those are coverage-dependent estimates — the rating assumes 5% of the page is printed, and dense documents will use the cartridges faster. The practical point is that a 2-pack turns reordering into a rare event for this class of printer.

How should the spare cartridge be stored?

Sealed in its bag, flat, in a cool dry place away from direct sunlight and heat sources. Stored that way, a toner cartridge keeps for a long shelf life without degrading, so there is no penalty for buying the second unit months before you need it. When the installed cartridge starts to fade, take it out and rock it gently side to side before you open the spare — redistributing the toner often recovers a surprising number of pages.

Are both cartridges covered if something goes wrong?

Yes — each 331-0778 in this pack carries the same 1-year warranty and 1-year free returns as a single unit, so a faulty cartridge is replaced or refunded under the same terms whenever it is opened. The policy in full is on our shipping & returns page, support runs Monday to Friday, 9 AM to 5 PM CST, and orders ship from IL, PA, GA or CA.
