Patent ID: 7856191

Claim:
A xerographic imaging device comprising: a first integrated marking engine, said first integrated marking engine selectively putting marks on output media during its operation; a second integrated marking engine, said second integrated marking engine selectively putting marks on output media during its operation; a power supply that selectively supplies selected levels of electrical power to the first and second integrated marking engines so as to get them ready for operation from a dormant state and to power their operation; a scheduler that quantifies a run time for a job and compares to a time to make ready the first integrated marking engine and at least a second integrated marking engine, wherein an amount of power from the available power supply is selectively distributed unequally to the first integrated marking engine and to the at least second integrated marking engine based on whether the run time using the first integrated marking engine exceeds the time to make ready the first and second integrated marking engines; and, wherein the power supply produces an amount of power that is available for selective and unequal distribution to the first and second integrated marking engines to get them ready for operation and to power their operation based upon a desired balance between a first page out time and a time duration to achieve full productivity of at least the first and second marking engines.
