Specifications:
Premium professional grade toner refill. This toner produces high quality text and graphics on plain paper. Each factory sealed bottle contains one pre-measured refill specifically formulated for use in the cartridges and printer models shown below. Our refill kits and accessories are intended to be used with original OEM cartridges only.

Reset Options:
Brother printers with toner page counters like the models listed below must be reset when the toner light comes on. Otherwise, the printer will stop printing even though the cartridge has toner in it. The printer can be reset two ways...1) mechanically - by setting the reset gear on the back of the toner cartridge...or...2) electronically - through the operation panel. We only support the electronic method at this time. It is the easiest method and it also allows you to reuse the starter cartridges. Reset gears are available in the Accessory section above if they are your preferred method of reset but we do not provide installation instructions. All regular replacement cartridges are equipped with reset gears. The starter cartridges that come with the printer cannot be equipped with a reset gear. Therefore, you will not be able to reuse the starter cartridges if you intend to use the mechanical reset method.

Refill Method Overview:
Simple instructions show where the existing factory fill hole is located. This hole can be used to refill the cartridge easily. Only a screwdriver and pliers are needed.
Refilling time is approximately 10 minutes.
