A printing device is provided comprising multiple marking engines including at least one marking engine and at least another marking engine that during operation place marks on output media. A power supply is further provided that selectively supplies selected levels of power from the at least one marking engine to the at least another marking engine for selected times so as to rotate readiness from the at least one marking engine to the at least another marking engine for operation to and from a dormant state. Power from the power supply is selectively distributed to the multiple marking engines so that the at least one marking engine is readied for operation while the at least another marking engine is removed from readiness.
