Frequently Asked Questions

Our paperwork lists 593-BBBU, 593-BBBT, 593-BBBS and 593-BBBR — is this listing that same set?

Yes — this is the reorder edition of exactly that set. The four numbers in the listing's title are the four cartridges: the 593-BBBU black, the 593-BBBT cyan, the 593-BBBS magenta and the 593-BBBR yellow, the high-yield supplies for Dell's C2660dn. If your last invoice, your stock list or the label on the cartridge you just pulled carries those numbers, you are looking at the same set you bought before — no translation from printer names needed.

Which of the four numbers is which color?

In the order the family is always listed: the 593-BBBU is the black, rated at 6,000 pages; the 593-BBBT is the cyan, the 593-BBBS is the magenta and the 593-BBBR is the yellow, each rated at 4,000 pages. Every cartridge is labeled with its own number and color and fits only its own slot, so a reorder that starts from a single empty cartridge is settled by matching the number on that cartridge to this list.

Why is the black rated so much higher than the colors?

The 593-BBBU's 6,000-page rating against 4,000 for each of the 593-BBBT, 593-BBBS and 593-BBBR reflects how the machine is used: text volume runs through the black, while color is spent on the pages that need it. The consequence for reordering is a stagger — the colors from a set are consumed first, and the black typically still has life when the first color slot empties. Restock timing in this family is read off the colors, not the black.

What does the set cost, broken down?

$70.35 for the four cartridges — about $17.59 per cartridge on average. On the ratings, the black works out to roughly 0.29 cents per page over its 6,000 pages, and each color to roughly 0.44 cents per page over its 4,000. As a reorder line it replaces four separate part-number purchases with one, at the same per-cartridge figures the family carries everywhere it is listed.

Are these the same as the Dell-manufactured cartridges on our old invoice?

They match the same part numbers, but they are not Dell-manufactured — they are compatible cartridges built to the 593-BBBU, 593-BBBT, 593-BBBS and 593-BBBR specifications. What stands behind them is our cover: a 1-year warranty and 1-year free returns on every cartridge, with the details on our shipping and returns page. For most reorders, the numbers matching is the point — and the numbers match.

Where does the set ship from, and how do we get help?

Orders ship from the nearest of our four US warehouses — Illinois, Pennsylvania, Georgia or California. Support is available Monday to Friday, 9 AM to 5 PM CST, and the 1-year warranty and 1-year free returns window covers every cartridge in the set. The full compatible range for the C2660dn family is on our Dell toner page.

We have just pulled an empty cartridge — how do we time the next order from here?

Start with the number on the empty cartridge: it names the slot that finished first, which in this family is normally one of the colors. Then check the levels of the three cartridges still in the machine. If another slot is also running low, the shelf set is being consumed and the next order should go in now, while the cartridges still in service cover the machine during delivery.

Our stockroom holds several of these sets — how do we keep them straight?

Date every carton on arrival and always draw from the oldest set first. The part numbers — 593-BBBU, 593-BBBT, 593-BBBS and 593-BBBR — are identical from set to set, so the arrival date is the only thing distinguishing fresh stock from old. A dated rotation keeps any one set from aging forgotten at the back of the shelf while newer cartons are used around it.

A replacement cartridge will not seat properly — what should we check?

The number, before anything else and before applying any force. Each cartridge in this set fits only its own slot, and a cartridge that resists is usually simply the wrong member of the set for that position: check its label against the slot — 593-BBBT is the cyan, 593-BBBS the magenta, 593-BBBR the yellow and 593-BBBU the black. A correctly matched cartridge seats without persuasion.

Why does our office go through these sets faster than the ratings suggest?

Coverage. The 6,000-page rating on the black and the 4,000-page ratings on the colors assume standard document pages. An office printing dense graphics, a chart on every page or photo material spends color toner far faster per page than a text office does, so its sets cycle sooner. Your reorder interval is set by what you print, not by the calendar — the same set can last one office a quarter and another a year.
