    摘要: A reprographic machine having a plurality of operating subsystems employs a setup procedure that prevents use for copying until all subsystems reach operating conditions. To avoid the need for time lost in the setup procedure where a power shut down is short, a bypass system, which senses the duration of the shut down, is utilized to allow prompt return to the copy function. Heated elements, such as fuser rolls, motors, and the like can be utilized to provide a timing function, based on temperature decay characteristics relative to time. The sensed temperature can be used as a control parameter for allowing bypass of the setup procedures.

    摘要: In a plural color printer or copier in which marking materials (e.g., toner) of at least first and second different colors are utilized, especially where the first color is the most commonly used (normally, black), with a common cleaning system for removing marking materials not fully utilized for imaging; an automatically actuated gate system selectively connects the cleaning system via a transport path to a purging dump, or, connects the cleaning system to a toner reclaim path to the image development station using that toner. The gate system is maintained in the purging position when the printer or copier is utilizing any marking material of the second or other colors. The gate is maintained in the reclaim position when the printer or copier is solely utilizing the first marking material. There is also a preset purge cycle delay of the actuation of the gate following from whenever the printer or copier starts solely utilizing the first marking material of the first color, i.e., delaying gate actuation until after a copy count or preset fixed time period has expired which was preset to be sufficient to remove mixed (plural colors) toner from the cleaning and upstream toner transport system. This purge delay effectively prevents any deleterious amount of mixed toners from passing through the reclaim path to the first image development station. (This preset delay will be a function of the cleaning and transport system geometry and size of the particular copier.)
