Brother Genuine Cartridge TN770 Super High-Yield Toner

In my long experience using them, Brother toner cartridges are reliable and long lasting. They are easy to install. Also you can recycle them! I recommend them.

Brother 770 toner last way longer, fast delivery , very satisfied

Great product.

After having separate scanner and printers I decided to simplify when my color laser printer finally died. The Brother combo black and white printer/ scanner hit on all my requirements. All in one function (scanning,copying and printing) fairly small form factor, reasonably priced unit and toner cartridges and as of to date no issues even after running through 2 new cartridges. Simple easy to use software and while i dont really need the subscription toner app, it not a bad feature. All in all very satisfied.

I have ordered 3 of these high yield print cartridges and none of them have been even CLOSE to the advertised number of pages (and I only purchase genuine brother toner). The printer starts giving you a message about being "low" on toner far before it is. You can cancel this but after a few times it locks you out and you CANNOT USE THE DEVICE until you replace the toner, even if the print quality is perfect and there is plenty of toner left. False advertising for sure. The smart chip counts pages and does not actually assess how much ink is used. So if you print 4000 blank pages you will throw out an essentially full toner.

I barely started using a brand-new MFC-L2750DW around 11/01/22 & the cartridge that came with it was used up in less than 10 working days. I then installed a TN-770 but it is also dead. The total count reads 4543, Fax is 2003 & Copy is 471. We are a low volume small office & don't have heavy usage of fax & copies.

Very disappointed to learn that TN770 is not interchangeable in all machines that take TN760. As someone who uses these in an office with multiple printers, it's an inconvenience and ends up costing more money. If one machine can take TN 760 OR TN 770, the other machine should be able to take TN 770 as well, but no, now it will only work in a few machines. I have requested our IT not install anymore Brother printers.

I agree with many of the low ratings. I'm lucky to get 1000 pages from a single toner cartridge. I will never buy another brother printer. I print tax returns so there is a lot of words on a lot of the pages but not single spaced and there's a lot of pages that have the bare minimum, such as vouchers and less populated pages. I have a Brother MFC-J4535DW that will not print straight lines or clean print. I've done everything possible. I am so done with Brother!

Not even close to 4500 pages! Replaced a new, not refill 770 about 2 months ago and I have been very disappointed with how long it lasts. I think I am going to go with the locally refilled because I can get them for 1/3 the price and they seem to last as long.

After years of good results with Brother printers, I now have a problem with the MFC-L2750DW. For some reason, it will no longer work with the TN-770. I don't know if it is due to a software update or a change with the cartridge. Either way Brother support says the printer needs servicing. The printer works fine with the old TN-770 cartridge and new TN-730 cartridges. A 2nd MFC-L2750DW in our office now has the same problem.
