Refilling toner cartridges is actually easier than refilling ink cartridges. Toner cartridges can usually be refilled 2-3 times before the print quality starts to degrade. All toner cartridges are different so it's critical to have the right toner, tools and instructions for your cartridge. Our refill kits are NOT generic refill kits - the toner and instructions are designed specifically for your cartridge:
