An Interrupt Manager for servicing interrupts. An interrupt is performed only after an atomic operation (Operating System instruction) is completed. After completion of each operating system instruction, a first command immediately allows any interrupt to be serviced. A second command then immediately closes out any interrupts, allowing for the execution of the next operating system instruction.

In a control system for an electrostatographic machine having a plurality of operating components, the operating components cooperating with one another to produce impressions on support material, said control having at least one microprocessor and a plurality of priority interrupts for interrupting the microprocessor to change control of said operating components, the control including an operating system responding to operating system instructions and commands, the operating system instructions corresponding to assembly language instruction in the microprocessor, the method of controlling operating of the machine including the steps of executing an operating system instruction, upon completion of each operating instruction, acknowledging a first command to service an interrupt, and upon a given time period, acknowledging another command to close out the acceptance of interrupt signals allowing for the execution of the next operating system instruction to continue control of the operating components whereby after the completion of each operating instruction, there is a brief time period interrupt window in which internal requests or interrupts from the internal control of the electrostatographic machine can be serviced.
