The Brother HL-4050CN (a single-function mono laser printer) prints through the TN115 series; this listing is its compatible high-yield version — the longer-running step up from the standard TN110 series (2,500 pages in black, 1,500 per color). Ratings run to 5,000 pages for black and 4,000 pages per color cartridge. It comes with our 1-year warranty, and you have a full year to return it free if anything is wrong.
Frequently Asked Questions
How do I keep color output balanced on the HL-4050CN as cartridges age at different rates?
Watch each supply independently — this platform reports levels per cartridge, and each of cyan, magenta and yellow (4,000 pages each) is replaced the moment it empties rather than on a group schedule. Black is managed the same way: this TN115BK runs 5,000 pages at $44.92 (about 0.90¢ a page), so it typically needs attention less often than any single color.
Which printers use this black?
It is built for the TN115 platform: DCP-9040CN, DCP-9045CDN, HL-4040CDN, HL-4040CN, HL-4070CDW, MFC-9440CN and MFC-9450CDN
Does an aging black cartridge throw off color balance?
A nearly-empty black can wash out shadows and text in color documents before it fails outright. Because the TN115BK's capacity is generous, the practical fix is simple: replace black when its output fades rather than squeezing the last pages out of it, and your color work stays true.
Should I ever change all four cartridges at once?
Only when all four are genuinely near empty — then the TN115 four-color set ($127.02) is the economical single order. Routine practice on this platform is one cartridge at a time, guided by the printer's own level indicators.
How does the TN115BK's lifespan compare with the colors'?
Black is rated at 5,000 pages against 4,000 for each color — but real consumption depends on your documents. Text-heavy offices exhaust black first; graphics-heavy ones cycle colors faster. The standard-yield TN110 line (2,500 black / 1,500 colors) preserves the same relationship at smaller scale.
What guarantee do I get?
This compatible cartridge carries a one-year warranty plus one-year free returns, set out on the shipping and returns page. It ships from IL, PA, GA or CA; support hours are 9 AM–5 PM CST.
About This TN115BK for the HL-4050CN
Color balance on a four-cartridge machine is a juggling act, and black is the ball most people drop — it fades quietly while the colors still look rich. This TN115BK lengthens black's arc to 5,000 pages at about 0.90¢ each, so its replacement rhythm is easier to anticipate and rarely surprises a color job. Keep each supply on its own watch, and the HL-4050CN stays consistent. Companion cartridges are on the Brother supplies page.
