The Canon 3785B002AA is known for its simplistic design and it is this design that makes remanufactured alternatives so very reliable. The cylindrical Canon C-EXV34 yellow toner cartridge contains enough compatible yellow toner powder to produce an estimated 19,000 prints, resulting in a very low cost per page.Although this 3785B002AA toner cartridge has not been produced by Canon, you can still expect superb print quality from the very first print you roll off! This is thanks to many components from the genuine Canon 3785B002AA being reused, in conjunction with a variety of compatible parts.
