Abstract:
1. An apparatus for mutually converting signals between a plurality of modular printing devices and a document processing system, the apparatus comprising: a device controller having a network interface for communicating with a system communications channel, memory for storing data and control code related to the operation of the modular printing devices, and a processor for running the control code; a digital input/output controller for receiving and sending document processing signals; a connector for receiving and sending modular printing device signals; and an optical input/output isolator for optically isolating the signals received via the connector; wherein the document processing system comprises a multiple feeding and finishing architecture (MFFA), wherein at least one of the modular printing devices comprises a device compatible with document finishing architecture (DFA) and wherein the modular printing device signals comprise one or more DFA signals.
