Abstract

See full text

A printing device includes: multiple marking engines that during operation place marks on output media; and, a power supply that selectively supplies selected levels of power to the marking engines for selected times so as to ready the marking engines for operation from a dormant state. Power from the power supply is selectively distributed to the multiple marking engines so that at least one of the marking engines is readied for operation prior to at least one of the other marking engines.
