Frequently Asked Questions

We print long two-sided reports on the HL-4040CDN — how far does one black cartridge go?

Yield counts printed sides, so a 100-page report duplexed onto 50 sheets still uses 100 pages of toner life. This TN115BK carries 5,000 pages for $44.92 — about 0.90¢ per side — which translates to roughly fifty such reports before black needs attention. For document-length work, that endurance is the point of the high-yield size.

Which models does this fit?

The TN115BK is made for the TN115 platform: DCP-9040CN, DCP-9045CDN, HL-4040CDN, HL-4040CN, HL-4070CDW, MFC-9440CN and MFC-9450CDN

Does duplex printing use more toner per page?

No — each side receives the same toner whether it shares a sheet or not. Duplexing saves paper and shelf space for thick reports; the cartridge's 5,000-page rating is unaffected by how you arrange those pages.

How does running color charts in our reports affect black?

Charts and headers draw on the color cartridges — TN115C, M and Y at 4,000 pages apiece — while body text draws on black. In a typical report the text dominates, so black remains the consumable to watch; each color is swapped on its own when it finally empties.

Is the TN115BK worth it over the standard TN110BK for long documents?

Decisively. The TN110BK stops at 2,500 pages, which can mean a cartridge change in the middle of a reporting cycle. This cartridge doubles that to 5,000 pages at a lower per-page cost. And when the whole supply set ages out, the TN115 four-color set ($127.02) refreshes everything together.

What protection is included?

One-year warranty, one-year free returns — the policy is spelled out on the shipping and returns page. Stock ships from warehouses in IL, PA, GA or CA; support keeps 9 AM–5 PM CST hours.

About This TN115BK for the HL-4040CDN

Long documents expose small cartridges: nothing breaks a deadline like a toner warning at page 3,800 of a print run. With 5,000 pages at roughly 0.90¢ each, this TN115BK gives the HL-4040CDN the stamina its duplex workflow assumes. It is the high-yield black for people who measure documents in chapters, not pages — matching colors are listed under Brother toner.
