Frequently Asked Questions

Why does the second cartridge in this 2-pack add only $17.90 to the price?

Because the pack pricing steps steeply. One 593-BBMF on its own costs $36.40, but two together cost $54.30 — so the second cartridge effectively rides along for $17.90, barely half the single price. That brings the per-cartridge cost down to $27.15 and the per-page cost to about 0.45 cents across the pair's 12,000 rated pages. Compared with buying two singles at $72.80, the 2-pack saves $18.50.

What is the practical point of owning two cartridges at once?

Continuity. One 593-BBMF goes in the printer and the second waits on the shelf, so the day the installed cartridge fades out, the swap takes a minute instead of becoming an urgent order. For a Dell S2810dn or H815dw that other people depend on, that spare is the difference between a non-event and a stalled workday.

Does the spare cartridge go bad sitting in its box?

Not on any timescale that matters here. A sealed 593-BBMF kept in a cool, dry place away from direct sunlight stays ready well beyond the time a typical office takes to finish the first cartridge's 6,000 pages. Store it flat, keep the packaging intact until install day, and it will perform like the first one did.

How far do 12,000 pages actually stretch?

At 500 pages a month, the pair covers about two years. At 1,000 pages a month it is a year, and a busier shared printer at 2,000 pages a month will work through both cartridges in roughly six months. However you slice it, the 2-pack turns toner into a twice-a-year-or-less decision instead of a recurring errand.

We run both an S2810dn and an H815dw. Does one 2-pack serve both?

Yes — both models take the same 593-BBMF black cartridge, so a single 2-pack can feed either machine. That shared design is what makes the spare strategy simple: whichever printer runs dry first takes the shelf cartridge, and there is no wrong-box risk when someone else does the swap.

What warranty and returns cover this 2-pack?

These are compatible cartridges, not Dell originals, backed by a one-year warranty plus one-year free returns, as set out on our shipping & returns page. Orders leave from the closest of our warehouses in Illinois, Pennsylvania, Georgia and California, and our support team is available Monday to Friday, 9 AM to 5 PM CST.

What should we check when the 2-pack arrives?

Confirm both cartridges are present, both are marked 593-BBMF, and both seals are unbroken — then write the delivery date on the spare's carton before it goes to the shelf. That date is the pack's rotation record: the cartridge installed today and the one waiting are the same age, but once a future order joins them, the date is what guarantees the older spare is used first. A two-minute inspection at the door also means any delivery problem is raised while the order is fresh, not discovered on the day the printer runs dry.

Is it worth writing anything on the cartons as the pack is used?

Yes — the install date and, if you keep one, the page counter, noted on each carton as its cartridge goes in. Across a 12,000-page pair, those two small records tell you exactly how long the first 593-BBMF lasted in your office's real mix, which converts the second cartridge's remaining life from a guess into an estimate. When the spare is installed, its carton note also marks the moment the shelf went empty. Offices that keep this habit stop being surprised by toner entirely; the pack's own cartons become the maintenance log.

When exactly should the next order be placed with a 2-pack strategy?

The day the spare cartridge is installed. That moment — not the low-toner warning, which the first cartridge already produced months earlier — is when your stock reaches zero, and it is also the moment you have the most time: a fresh 6,000-page cartridge has just gone in. Order then, and the replacement pair arrives with months to spare, at the pack's lower per-cartridge price rather than at single-cartridge urgency pricing. The rhythm sustains itself: every spare installation triggers the order that restocks the shelf, and the printer never becomes the reason an order was rushed.

How should the two spent cartridges be handled?

Keep them in the pack's carton, marked spent, until the cartridge that replaced each has proven itself. The first empty goes back into the carton when the spare is fitted; the second joins it when the next pack's first cartridge goes in. That way a spent 593-BBMF is never loose on the supply shelf where it can be mistaken for stock, and if the output of a new cartridge is ever questioned, the unit it replaced is on hand for comparison. Once both replacements are printing cleanly, the carton of empties can leave together and the shelf returns to holding only cartridges with toner in them.
