Frequently Asked Questions

Why is this set sold under four part numbers instead of a printer name?

Because the four numbers are the exact identity of what the machine consumes. This set is one each of the 593-BBBU black, the 593-BBBT cyan, the 593-BBBS magenta and the 593-BBBR yellow — the high-yield cartridges behind Dell's C2660 and C2665 color laser family. Printer names get reused across regions and sales channels, but a supply list never changes: if your machine's documentation or its own supply screen names any of these four numbers, this is the family it feeds from. Purchasing departments that order by part number use this listing because there is nothing to translate.

Which of the four numbers is which color?

The 593-BBBU is the black, the 593-BBBT is the cyan, the 593-BBBS is the magenta and the 593-BBBR is the yellow. Each cartridge is labeled with its number and its color, and each fits only its own slot, so a full set change is four deliberate swaps with no ambiguity about which cartridge goes where. If you are reordering after a single color has run out, match the number printed on the empty cartridge against this list and you have identified it exactly.

Why is the black rated at 6,000 pages while each color is rated at 4,000?

Because the two classes do different work. The 593-BBBU black carries text — the bulk of what most offices print — so it is built with a 6,000-page rating at the standard 5% coverage. The 593-BBBT, 593-BBBS and 593-BBBR each carry a 4,000-page rating. The practical consequence is a stagger: by rating, each color slot will call for replacement well before the black does, so restocking in this family is planned around the colors, not around the set as a whole.

How does the $70.35 set price break down?

Spread evenly, $70.35 is about $17.59 per cartridge. Set against the ratings, the black works out to roughly 0.29 cents per page and each color to roughly 0.44 cents per page — the honest arithmetic for a high-yield color family, with no cartridge in the box priced as a premium item and none as a filler. Bought as one set, the four numbers become a single line item instead of four separate purchases arriving at four separate times.

Are these Dell-manufactured cartridges?

No — these are compatible cartridges built to the 593-BBBU, 593-BBBT, 593-BBBS and 593-BBBR specifications, not cartridges manufactured by Dell. That distinction is exactly why the part numbers matter: the compatibility rests on matching the machine's specified supplies, not on a logo. What stands behind the set is our own backing — a 1-year warranty on every cartridge and 1-year free returns, with the details on our shipping and returns page.

Where does the set ship from, and how do we reach someone if a cartridge misbehaves?

Orders leave from whichever of our four US warehouses — Illinois, Pennsylvania, Georgia or California — puts the set on the shortest route to you. If a cartridge underperforms, support is available Monday to Friday, 9 AM to 5 PM CST, and the 1-year warranty and 1-year free returns window means a problem cartridge is a replacement conversation, not a loss. The full compatible range for this printer family is collected on our Dell toner page.

One color has run out but the others still print — do I change the whole set?

No. Each cartridge in this family serves its own slot, and the sensible change is the empty one only. Because the colors are rated at 4,000 pages against the black's 6,000, the slots empty at staggered times by design, and replacing a 593-BBBT cyan that still has life in it wastes the pages you already paid for. Keep the unopened remainder of the set sealed in its box, and change cartridges one slot at a time as each genuinely runs dry.

Our prints have lost their blues — which cartridge is responsible?

Work from the symptom. Weak or missing blues and greens point at the 593-BBBT cyan; reds turning orange and purples shifting blue point at the 593-BBBS magenta; a yellow cast disappearing — greens going blue, oranges going red — points at the 593-BBBR yellow; gray, washed-out text with healthy colors points at the 593-BBBU black. Print the machine's color test page and compare the four solid blocks: the pale block names the slot. That check takes a minute and prevents replacing a healthy cartridge.

How should restocking be planned when the colors empty before the black?

Plan around the colors, because the ratings guarantee the stagger: each color slot is rated at 4,000 pages, the 593-BBBU black at 6,000. In practice the first color call comes well before the black, and the colors themselves do not empty together — the one carrying your heaviest coverage goes first. Watch the supply screen's color levels rather than the calendar, and reorder the individual color by its number when its level drops, instead of waiting to buy a full set under time pressure.

How do I reorder a single color without buying the set again?

Order by the number on the empty cartridge — 593-BBBT for cyan, 593-BBBS for magenta, 593-BBBR for yellow, 593-BBBU for black. The number and the color are both printed on the cartridge label, and each number identifies exactly one slot, so there is nothing to translate and no printer name to match. Singles from this same family are listed individually, which is what makes the staggered replacement pattern practical: the set establishes the family, the numbers maintain it.
