Frequently Asked Questions

What does "2,400 pages" really mean on this cartridge for the MF244dw?

It is a standardised laboratory figure, not a guess. Cartridge yields are measured by printing a standard test page with about 5% of its area covered in toner, over and over, until the cartridge is exhausted. Five percent coverage is roughly a typical page of business text — a letter or a short report page. So the rating for the 137 translates as: about 2,400 ordinary text pages from the MF244dw. It is best understood as a comparison standard — every cartridge is measured the same way — and a planning figure that real offices land close to when their pages look like ordinary documents.

My pages are not "standard test pages." How far off could my count be?

It scales with how much toner your pages carry. A page that is half bold graphics might use several times the toner of a text page, so a cartridge spent entirely on such work could deliver well under half the rated count. At the other extreme, light text-only work can exceed 2,400. Most mixed office printing lands in a band around the rating — say 1,800 to 2,600 pages — which is why the honest way to use the number is as the centre of your plan, not its edge. Your cost per page moves with it: about 1.15 cents at the rating, on a $27.70 cartridge.

Why do manufacturers rate at 5% — is that realistic for our documents?

For text documents, yes. Measure a typical printed letter and the inked area really is in that neighbourhood — lines of text with white space between them cover surprisingly little of the sheet. Where offices drift above 5% is design: logos, shaded tables, heavy headers, presentation pages. If your MF244dw output is mostly correspondence, invoices and reports, the rating describes your life fairly. If it is mostly marketing material, expect less per cartridge and set your reorder rhythm accordingly.

Can I do anything to land closer to the rated figure?

Three small disciplines help. Use toner-save mode for internal drafts, which are a large share of most offices' pages. Avoid printing graphics-heavy pages unnecessarily — view proofs on screen and print only the final. And keep density at normal rather than pushed up, unless a document genuinely needs the richer black. None of these changes what the 137BK is; they change the average coverage of what you ask it to print, and average coverage is the whole game behind the headline number.

How does the yield figure help me compare cartridges fairly?

Divide price by rated pages and you get cost per page — the only honest comparison. This cartridge: $27.70 over 2,400 pages is about 1.15 cents. A cheaper cartridge rated far lower can cost more per page, and a pricier one rated higher can cost less. When every maker uses the same 5% standard, the arithmetic is apples to apples even if your personal yield differs from the rating, because it differs for every cartridge in the same proportion. Judge the 137 on that number and it holds up well.

What if my cartridge falls well short of the rating for no clear reason?

That is what the cover is for. This compatible cartridge carries a one-year warranty and one-year free returns, set out on our shipping and returns page.
