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 is reset by a reset gear on the toner cartridge. All regular replacement cartridges are equipped with a reset gear. The starter cartridge that comes with the printer is not equipped with a reset gear. Therefore, you will need to install a reset gear on the starter cartridge if you intend to refill it. Our gear turns a starter cartridge into a TN350 cartridge.

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.
