Apparatus and method to identify replacement of developing machine

摘要

An apparatus to identify a replacement of a developing machine comprises a fuse which is disposed at a desired position of the developing machine; a switching part which is disposed at a desired position of a printer body corresponding to the fuse and applies a level of current to the fuse according to a control signal so as to disconnect the fuse; a control unit which outputs a control signal to the switching part so as to check whether the fuse is disconnected when a warming-up operation of a printer is started, and which outputs a control signal to a power controller so as to disconnect the fuse if the fuse is not disconnected and then initializes a printing counter, wherein the developing machine is determined to have been replaced, if the fuse is not disconnected.
