BrotherGenuine TN420 Mono Laser Toner Cartridge, Black

Some reviewers have asserted that this is not a genuine Brother product, but the one I received is genuine. It comes in a Brother cardboard box with a UPS return label for returning the old cartridge to Brother.It was easy to install and the three page test print-out looks fine. I did see something odd in the test pages, which you can print by hitting the "Go" button three times in rapid succession: it states that I am printing at 600dpi and am not in Toner Save mode, but when I go to Devices & Printers in Windows and look at Printing Preferences, it shows differently, that I'm printing at 300dpi and am in Toner Save mode.This is the first cartridge I've bought for this printer; the original cartridge printed 821 pages. I probably would have printed more pages if I had set it to Toner Save mode and to 300dpi sooner. I didn't do it until just a week before the toner ran out.Many reviewers here have commented on the toner warning light coming on much too early. This led me to wait too long to order a replacement - by coincidence the toner ran out the first time I tried to print after ordering a replacement! I have a spare printer, so it wasn't a problem for me, but if you don't have a spare printer, don't wait too long to order a replacement cartridge.Amazon's prompt shipping helped. I have Prime and used standard two day shipping, but the cartridge arrived the day after I placed the order.I do have two complaints, and am knocking off one star for them:1) The inconsistency in reporting the DPI at which I'm printing and about whether or not I'm printing in Toner Save mode.2) The inability to see the toner level or number of pages printed without using up three pages printing it out.On the positive side, the printed report is thorough, which I like. I just wish I could see the toner level and pages printed without using up three pages and that much ink.UPDATE:I've just ordered my second of this toner cartridge. Just like the first time, it's the genuine Brother cartridge, including the return label for recycling the old one. I'm impressed enough that I'm raising my original 4 star rating to 5 stars.I got 2,371 pages out of this cartridge, compared to 821 pages for the stock cartridge that came with the printer. As so many others have reported, you'll get warnings that it's almost empty long before it needs to be replaced. In my case, I think it was about 600 pages before it was really empty.Near the end of its life, the printing looked like the ink had run out, but just running the tab on the corona wire back and forth a few times solved the problem. This happened twice before the ink actually did run out.I have two printers (the other is an HP 8100 Office Jet for color printing) and do a lot of printing. This cartridge and the HL-2270DW printer it's in have both proven to be reliable workhorses.

I have a laser brother printer for 15 years and still going. It is a solid printer, much better than ink ones that I need to replace every few years. I purchase a drum every few years, I always purchase this one and never failed on me.

Pros:Never-Ending Ink-ness: Seriously, is this thing powered by a magic well?Crisp Like Morning Air: Prints so sharp they could cut through awkward office small talk.Cost-Effective: Costs less over time than my daily caffeine fix.Super Simple Setup: No fuss, no muss, no interpreting confusing hieroglyphics.Cons:Office Celebrity: May overshadow other office supplies, leading to potential paperclip uprisings.The Verdict:You know you're an adult when a toner cartridge makes it to your top 10 list of 'exciting things.' But, let's ink about it for a second—this Brother Genuine High Yield Toner Cartridge is the unsung hero we all need but don't deserve.Firstly, let's talk about its longevity. This thing lasts longer than my New Year's resolutions. Seriously, I've printed reports, memos, accidental copies of my elbow, and the occasional recipe for 'emergency brownies,' and it's still going strong. It's like the Energizer Bunny of toner cartridges.Quality-wise, this bad boy is the Leonardo da Vinci of printing. It gives you lines so crisp and text so sharp you’d think each page was a miniature work of art. If you squint hard enough, you might even see the Mona Lisa in your quarterly reports.But what about the cost? Yes, upfront it feels like you're buying a small piece of the moon. However, considering it doesn't dry out after a few weeks—unlike those generic posers—you're actually saving money. It's the equivalent of choosing a reusable water bottle over a mountain of plastic ones.Installation? Oh, you mean the 15-second break from your desk where you pull one cartridge out and plop another in? So difficult, right? Wrong! It's easier than explaining why you're late to a Zoom meeting because you couldn’t find the link (again).Now, the only con I can think of is that it might just outshine all other office supplies. Seriously, don't be surprised if the paperclips and staplers get jealous. You may want to keep an eye out for any rebellious behavior—like paper jams or disappearing pens.In conclusion, if your printer is the heart of your office, this Brother Genuine High Yield Toner Cartridge is the lifeblood that keeps it pumping. Get one, and you won't just be the employee of the month; you'll be the monarch of the toner kingdom. All hail the ink-cognito superstar!

Came quickly and just want I needed for my work printer. Price was cheaper than our supplier too!

Works as expected. I just wish it wasn’t so pricy.

Cjheap and good

Great product works as stated

Love this toner (and the laser printer). Just bought this to replace a toner cartridge that I installed 5 years ago (I wrote the install date on the old cartridge). We don't print tons of stuff, but I shudder to imagine how many inkjet cartridges I would have gone through in the same time period. Brother also includes a shipping label so that you can send your old cartridge back for recycling in the box the new one arrives in. Much appreciated!
