Brother TN-780 DCP-8250 HL-6180 MFC-8950 Toner -Cartridge (Black) in Retail Packaging

I would give it 5 stars but the toner ran out before the high yield number (300 pages before) so not sure why. I will buy again and see if it was just a one time thing, but price was cheaper than office supply store too.

Reliable toner

First time trying out this super high yield toner for my 5470 printer. Noticed that this printer must have a page counter built into the software that locks up the printer after so many prints. On my older brother printers I can just tape the laser window and get an extra 2k to 3k prints. This one shuts down the printer after like 5500 prints and even putting tape over the window does not allow to print past that number. Also have seen that this one does leak more than any other cartridges I have used in the past. Ordered 2 more and will see if the next two are just as bad as this first one.** update 8/1/2013 **After using these more I will update that I have grown accustomed to these. Maybe I had a bad batch to begin with but so far the new ones seem to be holding up better. Still would like to see a more consistent number of prints from each one considering I only print text documents. But for the price these are the least expensive price per print toner you can get.

I was really excited to get the  Brother HL6180DW Printer  - and a big part of that was the availability of this super high yield printer cartridge.Because we print so much, the initial cartridge that came with the printer only lasted a few days, and then we switched to one of these babies. The print quality is excellent and the installation was easy; although, I will admit I expected it to weigh just a bit more because of the additional toner capacity.One thing to watch for with these cartridges is that there is a small window that the printer uses to determine when the toner is out. The problem is that you can typically get almost 1000 more pages after the toner passes the level of that window. The easy fix is to add a small piece of tape over the window after the printer thinks it's out of toner. That will give you a chance to pick up a new toner cartridge before it really does run out (which is obvious because the print quality drops off really fast).Overall, I would highly recommend these toners. It's less hassle because you don't have to change toner as much, and it's also very cost efficient.

I have been a long time user of Brother Printers for both business and home. I just bought an MFC-8950DW for our small office to use as a network printer and photocopier. What attracted me to this printer besides its awesome features and airprint support, was the TN-780 12,000 page capacity cartridge. We currently have 5800 pages on the printer. We used the included cartridge which lasted maybe 1500 or so pages, then placed our first TN-780 in about 5 weeks ago.It ran fine until this week when it started spewing toner all over the inside of the printer. I don't mean a little leak. I mean massive amounts of toner. It is coming from the left front corner. All you have to do it tip the cartridge to the lest and down a little bit and you get a pool of black powder on the floor.Being a good technician, I cleaned it once to give the benefit of the doubt that maybe something just got stuck and need to get purged out. I did a thorough cleaning inside the printer and drum unit. Put the cartridge back in and within 10 prints it was doing it again.So, Just today I called tech support. They were very helpful. They asked all of the dumb obvious questions. Once I got through that pain, They agreed to send us another cartridge. I wasn't done though. I was able to speak to supervisor. I am still concerned that there is so much crusted, flaking toner inside the drum that it may have scratched the drum. I requested a replacement drum as well to be safe. The Supervisor felt like the drum would clean itself off with a properly functioning cartridge in place.So, for my rating, I am giving 3 stars that I had to go through all this. I will update if the support call fixes my issue and the drum self cleans as described. I will say, support was excellent in getting a new one sent, but as of now, it has not arrived yet.

I use these in my  Brother Printer HL6180DW Wireless Monochrome Printer  for printing copies of receipts in my store. At first was a annoyed by the lacking of pages I printed from these cartridges, until I saw another review that said to tape off or color in the 2 windows (one on each end) of the toner cartridge. Once I had done that, these cartridges run forever. Now I run them until the prints become too faint to read. I am getting well over the listed number of prints out of these cartridges now.Others have reported leaking toner but I have seen none of that.

easy to install and use. quality of printing very good.

Great product except pages get caught in copying i.e. 2 pages will go through at one time. Also the opening and closing of top peice feels (to copy on glass) feels like it is unstable and will not last long. But so far doing what we need it to do.

Amazons pricing on printer ink is fairly inconsistent so I often look around before buying here. That said I always look for brother ink for our brother printers. I have tried some no name versions of ink for our printers but it never seems to work as well. The quality of printing with brother ink is worth the price difference for our office.

As mentioned on some of the other reviews this product has issues with toner leaking out into the drum unit and into the printer itself, causing messy print quality. This requires quite a bit of cleaning to make sure that the print quality is reasonable. Also 1 out 5 of these that I have used crapped out with what seems like 1/2 of the toner still left.

Super fast shipment, exactly as advertised!

Genuine product and fast delivery.
