A Little Pricey, but Worth it: Brother Toner TN-210 Cartridge Set, 4-Pack, Black, Cyan, Magenta, and Yellow

Buying them as a set of 4 saves a few bucks over buying singly. Official Brother laser ink drums. Includes a set of four, one drum for each color. Arrived promptly. They are still significantly more than the off-brand or refilled versions, but over the length of time you probably use a set.

The first few pages were a bit light, but now the Toner TN-210 Cartridge Set perform better than the originals that came with the unit. Cartridges are super easy to install and colors are vivid. Time will tell if I actually get the 1400 copies stated on the package, but if not, there's a way to extend cartridge life. Just Google the Brother printer model and add "toner override" then scroll down the forum for instructions. 

• OEM Toner. Mono Laser Supplies
• Set Includes Brother TN-210BK, TN-210C, TN-210M, TN-210Y

It's great quality and the price I paid was much less than buying it from Brother or from a Big Box office store. I thought I was ordering a remanufactured cartridge, but this came in a Brother box and as far as I can tell, is an authentic Brother cartridge. So I'm a bit confused, but am not complaining at all. Works great and was a great price.

The overall savings for the gray-market versions will be limited, and it gives you the consistent performance and repeatable cartridge life. I keep one Brother Toner TN-210 Cartridge Set, 4-Pack, Black, Cyan, Magenta, and Yellow on the shelf so I can replace as soon as I need to, and the storage time has never caused any problem. I am happy I am getting what I pay for.

Here's how toner override works on my machine. Yours might be a little different, so experiment to make it work, but just remember that there should be a way to override and keep printing even though the toner's low:

1. Open the door as if you're going to replace the toner (but don't replace).
2. You might have to press the "menu" button.
3. Press the "clear" button.
4. Scroll with the down arrow until you see the color that has "run-out"
5. Press "OK" to reset (#1 on my machine)
6. Finally close the door again. The printer should now reset itself and keep printing. You might have to press "start" or cycle the power on and off again.
7. Remember that you're almost out of toner, so make sure that you have a replacement cartridge available.
