Cartridge Charger toners are produced with precision to create the most accurate color. All our toners go through multiple rounds of quality testing prior to release. Cartridge Charger does not use any generic toners for multiple printer models. This toner has been mixed and engineered specifically for use in the model specified above. Check our specifications for more model specific information. All our kits include sealed toner bottles electronically measured and filled, smartchips (only if indicated above), and an easy refill funnel. Our instructons, if available are listed on our tech site at www.tonerforums.com. If you have any questions please contact us.
