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:
Samsung 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. We strongly recommend replacing the chip on your toner cartridge when refilling it unless you have installed reset software in your printer and do not need reset chips any more. Please note that these printers use different toner cartridges for different regions of to world. The cartridges require specific chips that are compatible with the region of the world in which the printer was purchased. If the kit ordered includes a reset chip, it will be compatible with the region the kit is being shipped to unless we are otherwise instructed on the order.

Refill Method Overview:
Simple instructions show where to make a hole in the cartridge for easy refilling. Our Universal Hole Tool is recommended because it makes a clean fill hole quickly and easily without creating shavings that can fall into the cartridge like drilling does. This tool operates on 110V~120V power. If the power source in your location is more than 120 volts, we recommend using a voltage converter/adaptor that is designed to be used with American appliances.
Refilling time is approximately 10 minutes.
