Cisinks® Universal Toner Refill for Brother TN420 TN450 TN540 TN630 TN650 TN660 TN720 TN730 TN760 TN770 TN780 TN850 Toner Powder Black

Love the sealed container with funnel tip. Just used some of this to fill up my old cartridge. The seal ensures freshness and the funnel tip makes the filling process clean and easy. This toner is working well so far with my Brother HL2880DW printer. At 180g, this is enough to completely fill up a TN450 cartridge, twice.

I used to buy expensive toner, I thought to give chance to this refill, and its works fine. Easy to use, and the price is great.

A much cheaper alternative to buying the official cartridge! A no brainer to save money!!!

You're going to like this one. I use this powdered ink to "age" the surface of the sealant I apply around my pool and deck. The gaps and cracks need to be filled, so I use Deck-o-Seal. That caulking is tan in color but over the years the original tan sealant has worn to look slightly greyer and splotchy. Enter the ink. Just a little sprinkle in my wet sealant application and boom. Matchy-matchy. No afterthought look, either. Jeenyis, huh?

Print quality is mediocre and makes a mess. The toner is not even standard quality. Only good thing was it shipped fast and I needed toner quickly

This toner prevented a 10 day delay for a $60 toner cartridge. YouTube showed me the 10 minute refill process. I could not find any toner that claimed compatibility with Zerox but this works flawlessly. Thanks

Print quality is certainly NOT professional. I couldn't print a single copy of my resume using this ink. There's something wrong either with the ink or perhaps I overfilled my starter toner cartridge of a smaller capacity than the regular cartridge. My printed pages, for a long long time (hundreds of pages full of mostly text, and rarely with some small images) had small spots/blotches of ink throughout the page. The spots were grey and looked like small worms (about 1/2 centimeter or 1/4 inch) scattered across the page. Also, there were a TON of smudge marks covering the entire page as if the page was coated with a grey primer! Finally, there were thin lines concentrated in certain sections of the page. Now that the toner is mostly used up, the small worm-like spots and concentrated thin lines are mostly gone but the smudge marks continue to cover the whole page, just not as dark as they used to be when the cartridge was refilled. The most frustrating part is not knowing whether it's the bad ink or my overfilling the cartridge that caused the problem.

Removed used cartridge from HP3260 printer. Funnel top makes it very easy to install new toner into cartridge. But print is light gray rather than black.
