KEENKLE Compatible Toner Cartridge Replacement for Brother TN227 TN227BK TN-227 TN223BK TN223 for MFC-L3770CDW MFC-L3750CDW HL-L3290CDW HL-L3210CW HL-L3230CDW MFC-L3710CW L3270CDW Printer Tray, 5 Pack

I ordered these as a replacement for my Brother MFC-L3770CDW. They came with good instructions and were easy to install. There was one of each color, Cyan, Magenta, and Yellow, along with 2 Black cartridges. As you can see from the picture I included, the print quality shows a before printout on the left (with old cartridges) and on the right with the new cartridges are about the same. The blacks on the new cartridge are possibly a little better. The price on Amazon is much better than OEM prices and the quality in my opinion is as good. The printer accepted these cartridges without any problems and displayed full toner levels after installation.

I'm glad that others are finding success with this toner based on the reviews, but in my experience I am getting prints that are dull, washed out, and light to the point that they are almost hard to read.

Purchased 3 sets of these for printers at work. So far 3 of the cartridges could not be recognized by the printer. Not worth messing with. I will buy higher quality next time.UPDATE: Seller issued a refund but also offered to pay me off to remove my negative review. Definitely against Amazon's seller TOS! Sorry but my review of the terrible product still stands.

This is the second brand I’ve tried lately. Third party toners don’t seem to be working anymore with this printer. It keeps saying no toner. May have to bite the bullet and get the brother toner. Total bummer!

Cheaper alternative to OEM cartridge and works the same except for the message that it’s “Non-Genuine supply”. Toner level is indicated and updated to full after replacement. Test page printed fine and the lines are sharp and it didn’t smear and no excess powder on page.
