This laser refill kit contains all you need to refill your Color LaserJet Pro M454dn, M454dw, M479dw, M479fdn, or M479fdw cartridges.

• NOTE: To refill this cartridge model, you will also need a "Toner Cartridge Hole Making Tool" to pierce holes. The use of any other tool, including a drill, is not recommended to avoid damaging sensitive internal components. You can then use the provided easy-seal tape to seal the holes.
• Includes 4 bottles of Ink Owl premium formulation toner, 4 spouts for easy pouring, easy-seal tape along with detailed, graphic instructions.
• Our instructions will guide you step-by-step through the entire refill process and include pictures showing you exactly where the holes need to be pierced.
• With this cartridge, it is not mandatory to replace the chip since the low toner error can be bypassed. Since replacement chips for this printer are expensive, we recommend not replacing them. Our instructions will fully detail how to bypass the low toner error. In this way, you can print until the color starts to fade out, and then refill at that point.
• Includes 60g of each color toner powder for the full 2400-page yield of black and 2100-page yield of color (at 5% coverage) just like the original standard-yield cartridges.
