An electrostatographic type copying or reproduction machine incorporating a programmable controller to operate the various machine components in an integrated manner to produce copies is disclosed. The controller carries a master program bearing machine operating parameters from which an operating program for the specific copy run desired is formed and used to operate the machine components to produce the copies programmed. A multiple prioritized interrupt system interrupts the background routine in use to carry out the next scheduled foreground routine as appropriate. Since the interrupt interval is limited, overlong foreground routines, if called by the copy run programmed, are spooled by placing a portion or all of the overlong routine in background.
