Brother - TN850 High-Yield Toner Cartridge - Black

This cartridge gets the job done, but please do not be fooled into thinking you're going to get anywhere near 8,000 pages. Brother bases this estimate on a "term paper" page -- 250 words double spaced per page. Of course that doesn't conform to any reality. If you print loan documents like I do, with densely spaced text and some graphics, expect more like 5,300 to 5,400 pages.

So far, so good! It prints clear on my multipurpose printing paper, which means I don't have to waste money on high quality printing paper to get excellent print jobs. Brother A+++

This XL cartridge has worked flawlessly so far. No leakage problems like so many other brands. Of course I haven't had it long enough for it to go empty but if there are issues with the yield I will update review.

Bought a brand new Brothers printer and purchased these toners separately. This toners work great. They don't leave any marks or lines and are Brothers toners directly from Brothers company. You can't go wrong.

What can one say about a toner cartridge. Am still using the cartridge that came with the printer. Don’t anticipate any issues since I have used authentic Brother cartridges for 11+ years.

This high yield cartridge is great. Works fine and for the extra copies it will produce, well worth the additional up front cost

The XL cartridges give you a lot more page printing capacity for just a bit more money. If you can afford it up from the XL cartridges are cheaper in the long run.

Its pricy, but it does what we need in the office. Im just hope price is more reasonable, but it is still cheaper when compare to HP products.
