ABSTRACT:
A control system especially suitable for use in imaging forming equipment includes a program for controlling individual image forming loads in the form of tasks wherein each task controls all the image forming units associated with one recording paper. The tasks are processed in parallel by scheduler software operating in a multitask arrangement. Thus, software for executing the tasks in parallel is isolated from a main image forming program. In this manner, using modular programming techniques, the present control system implements a complicated control scheme using a collection of simple control modules. A single program is shared by the different tasks so that it is free from redundancy. Advantageously, the number of tasks may be changed by changing the capacity of a memory in accordance with an increase or decrease in the number of objects to be controlled.
