Frequently Asked Questions

Our whole team prints to the HL-4040CN — how do we keep black from becoming the bottleneck?

Choose capacity. A networked printer aggregates everyone's monochrome jobs onto one black cartridge, and the TN115BK's 5,000 pages at $44.92 (about 0.90¢ per page) stretches the interval between swaps. Teams that standardize on high-yield black simply stop thinking about toner most months.

What printers is it compatible with?

This cartridge serves the TN115 platform: DCP-9040CN, DCP-9045CDN, HL-4040CDN, HL-4040CN, HL-4070CDW, MFC-9440CN and MFC-9450CDN

Do teammates' color jobs drain this black cartridge?

Barely. Color pages consume mainly the TN115C, M and Y cartridges at 4,000 pages each. Your black level tracks the team's text and document output — which, in most offices, is the overwhelming majority of pages anyway.

Why does our office go through black so much faster than the colors?

Because office printing is monochrome at heart: emails, contracts, labels and reports rarely need color. That is normal for this platform, and it is exactly why the black cartridge is offered in a 5,000-page high-yield size while each color is replaced individually, only when its own work empties it.

TN110BK or TN115BK for a team printer?

The TN110BK yields 2,500 pages — on a shared HL-4040CN, that is a cartridge change twice as often, with someone always discovering the empty at the worst moment. The TN115BK's 5,000 pages make it the team-appropriate choice. If every supply runs low at once, the TN115 four-color set ($127.02) resets the whole machine in one order.

What backing does it carry?

A one-year warranty and one-year free returns cover this compatible cartridge; terms are on the shipping and returns page. It ships from IL, PA, GA or CA, with support hours of 9 AM–5 PM CST.

About This TN115BK for the HL-4040CN

Shared printers fail socially before they fail mechanically: the cartridge empties mid-queue and the job belongs to someone else. Doubling black capacity to 5,000 pages at roughly 0.90¢ each is the simplest fix — fewer interruptions, calmer queues. This TN115BK is that fix for the HL-4040CN, and its color companions sit on the Brother supplies page.
