Brother Genuine TN420 Mono Laser Toner Cartridge, Black

This toner lasts a long time. We print weekly, not a ton, but I think it lasted about 2 years. It also had been sitting in the box for over a year before I used it and when it was installed it works like a champ. It has a return the old cartridge option that they make easy. It is super easy to install, fits my HP printer well, we never have any leakage of ink from it, the print quality/darkness is good.

Great product. Have been re buying this product for years as it has been very reliable. Highly recommended. Great Value for the money. Long lasting toner and very easy to install. Does not damage the printer and print fast and clean.

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 last bought this two pack toner in November 2013. I use my laser printer a fair amount, but just not all the time. Now in June 2026, I just installed the second cartridge out of that box. It has been sitting in my drawer for almost 13 years and I am right pleased with its performance. The pages I'm printing are as sharp as before. As to some customers complaints about "the annoying low toner message", I just ignored it and kept printing until the printer refused to print until the toner was replaced. Sharp copies to the very end. If I'm still around the next time this printer needs toner, I believe I will return to this product.

Great product but way too expensive. Much cheaper options available

Works as you would expect. I've tried 3rd party toner for my Brother AIO with mixed results, but the OEM toner just works.

The ink I always use last long time and is very good

Excellent !
