Following standard industry wide practice, Brother has installed software/hardware in their printers to block the use of aftermarket or refilled printer cartridges. You can not simply pull out an empty Brother toner cartridge and replace it with an aftermarket cartridge and expect your printer to work. At least that was my experience. The Brother software would not remove the empty toner message. There are many solutions posted on the web explaining how to get a printer to work with after-market cartridges. Some required you to take the cartridge apart and re-assemble it, others explained how to re-program the software. I didn't feel comfortable taking screws and springs out of the cartridges and I could get none of the re-programing options to work. It took three calls to the Brother "help" line and 3 different tech reps before I found one who understood the problem and got the printer to work. One hung up on me, I hung up on one, and the third time was the charm, total elapsed time on phone 4 hours. If you're willing to put up with the hassle, these cartridges work fine and cost 1/6 original equipment. The print quality is equal to original equipment and I suspect they will last as long if not longer than "genuine Brother supplies". Read full review

Upon installation and running my very first print job with the newly installed cartridge, I was totally underwhelmed by the quality of print. The pages came out extremely faint...more like what you'd see when a toner cartridge is going out as opposed to a newly installed one. Subsequent print jobs gave me more of the same. So then I switched to the 2nd cartridge of the 4 that I'd purchased. Again, light, faint print on the page. My advice is that you strongly consider other options besides these...even if you have to pay a little more...you'll be glad that you did! What good is cheap if it doesn't really work anyway???

First off, the price is ridiculously economical for two, not one, of these high output cartridges. I've only used it for a week and it performs the same as the factory produced cartridge. I can't comment yet on how long the ink will last because I've only had it installed for a very short time, one week. The print quality is great, clean and clear with the right color shade. This cartridge lives up to the advertised quality.

Finally used one and compared to another cartridge. Seems to work pretty good. A little of light shading, but that may be due to the print drum assy. I will have to replace that to really make an accurate review, but at this point in time, these appear to be great cartridges and I do recommend them!

I have purchased these toner cartridges numerous times and I have had great luck with them thus far. Other than one mishap where one of them poured out the ink powder all over itself but luckily it was still sealed in its wrapper.
