New Era Toner - (180g/140g) 4 Color Toner Refill Set for Brother (TN-431, TN-433, TN-436) MFC-L8610CDW, MFC-L8900CDW, HL-L8360CDWT, HL-L8360CDW, HL-L8260CDW Printer

The bottles supplied contain the exact quantity needed to fill the cartridges without overfilling. Make sure you empty the cartridges of old toner first (shake it out, don't use compressed air). Print quality is good. On the MFC-L8900 there is a feature in the settings menus to perform a color calibration. No flag gear necessary, toner levels can be reset on the printer with the following procedure posted by Reddit user hEnigma: "Open the toner door and press the back and cancel buttons at the same time (it will almost certainly take a couple of tries). You must be on the open door message, if you back out of it, just touch the message again in the top left corner." This toner kit does not come with caps for the cartridges, which should be bought separately as you will almost certainly destroy the original caps removing them.

I have bought this ink, thinking the powder will be full as shown in the containers. No issue with delivery, I got it when I needed it the most, but the volume is 1/3 of what you get in that picture for CYA, you will get a little more with the black powder. Aside from the quantity, the ink worked well.
