A method for optimizing a printing operation of an apparatus, being a copier or a printer, comprising a plurality of parts and adjustable power supplies coupled to these parts, wherein at least one part of the plurality of parts influences said operation of the apparatus, the method comprising the following steps: obtaining information about the at least one part of the apparatus influencing the operation of the apparatus from an information component of the at least one part, said information component comprising memory and a processor, and using the obtained information to determine instructions for optimizing said operation of the at least one part of the apparatus, said instructions configured to adjust the power applied to the at least one part, and applying the instructions to the information component for execution by the processor, characterized in that said information about at least one part comprises specification information on characteristics of the at least one part with which the at least one part is manufactured, said characteristics including electrical discharge characteristics if said at least one part includes a photoreceptor, electrical resistance characteristics if said at least one part includes a bias charge roll, and light intensity characteristics if said at least one part includes a full erase light or a laser diode, and either said at least one part having relaxed tolerances is a part with changing characteristics; and said using the obtained information includes determining a difference between the specification characteristics of the at least one part and, the current characteristics of the at least one part, or said at least one part having relaxed tolerances is a replacement of another part, and said using the obtained information includes determining a difference between the specification characteristics of the at least one part and the characteristics of said another part stored in memory of the apparatus. obtaining information about the at least one part of the apparatus influencing the operation of the apparatus from an information component of the at least one part, said information component comprising memory and a processor, and using the obtained information to determine instructions for optimizing said operation of the at least one part of the apparatus, said instructions configured to adjust the power applied to the at least one part, and applying the instructions to the information component for execution by the processor, characterized in that said information about at least one part comprises specification information on characteristics of the at least one part with which the at least one part is manufactured, said characteristics including electrical discharge characteristics if said at least one part includes a photoreceptor, electrical resistance characteristics if said at least one part includes a bias charge roll, and light intensity characteristics if said at least one part includes a full erase light or a laser diode, and either said at least one part having relaxed tolerances is a part with changing characteristics; and said using the obtained information includes determining a difference between the specification characteristics of the at least one part and, the current characteristics of the at least one part, or said at least one part having relaxed tolerances is a replacement of another part, and said using the obtained information includes determining a difference between the specification characteristics of the at least one part and the characteristics of said another part stored in memory of the apparatus.
