By re-using many original Canon 047 parts, this remanufactured alternative keeps the quality of print from your i-SENSYS laser printer high. Whatever cannot be recycled, is replaced with a top quality compatible Canon 2164C002 component, designed to work in harmony with the other pieces.The completed remanufactured Canon 2164C002 toner cartridge is then filled with a black toner powder produced to offer comparable results. With each remanufactured 047 unit offering the same 1,600 page estimated yield and coming fully guaranteed, we highly recommend this partially recycled Canon unit.
