Frequently Asked Questions

How do we put a defensible per-page cost on our 5100's black toner?

Start with the two numbers on this listing: $48.50 for the cartridge and a 9,000-page rating. Divided out, that is roughly 0.54 cents of toner per page — a figure you can put in a budget line or a chargeback spreadsheet without apology. It assumes standard 5% coverage, so if your 5100 mostly prints dense reports the real cost edges up, but as a planning number it is honest and easy to defend.

The label on our empty cartridge says 310-5807 — is this the same unit?

Yes. This listing is the compatible version of Dell part number 310-5807, the high-yield black cartridge specified for the Dell 5100 and 5100cn. Ordering by the number on the label is the safest habit in any stockroom: printer names get shortened, misremembered and mistyped, while the part number printed on the cartridge is exact. Match the number and you have the right black cartridge.

How many reams of paper does one cartridge cover?

A ream is 500 sheets, so a 9,000-page rating works out to about 18 reams before the black runs dry. Framed that way, most offices can picture their own consumption: if your 5100 goes through a ream a week, expect a cartridge to last the better part of four months; two reams a week and you are changing it roughly every nine weeks. Coverage matters too — heavy pages drink more toner than plain memos.

Why choose the high-yield black over a standard-fill one?

Because on a shared 5100cn the cost of a cartridge is only half the story — the other half is how often someone has to stop, open the machine and swap it. A 9,000-page fill stretches that chore out for months at a time and keeps the per-page cost near half a cent. For a printer that several people depend on, fewer interruptions are worth as much as the toner saving itself.

Is this Dell's own branded cartridge?

It is not. This 310-5807 is a compatible cartridge manufactured by a third party to Dell's specification, which is why it sits at $48.50 rather than at genuine-brand pricing. The page rating, the price and every claim on this page refer to this compatible unit and nothing else.

What happens if the cartridge underperforms?

It comes back to us. The cartridge is covered by a 1-year warranty with 1-year free returns, so early fading, streaking or an outright failure is our problem to fix, not yours to absorb. Our support team answers Monday to Friday, 9 AM to 5 PM CST, and the complete policy is set out on the shipping & returns page. Stock ships from IL, PA, GA or CA depending on which warehouse is nearest.
