A modular toner image producing machine having plural modules including redundant modules is provided and includes (a) a photoreceptive module including a movable endless photoconductive member having an image bearing surface; (b) toner image forming modules for forming a toner image on the image bearing surface, each of the toner image forming modules including module-specific fault detectors; (c) at least one sheet feeding module for feeding a copy sheet to receive the toner image from the image bearing surface; (d) a fusing module for heating and fixing the toner image onto the copy sheet forming a hard copy; (e) at least one finishing module for preparing and arranging a series of hard copies into sets thereof for removal by an operator; and (f) a control module including a main electronic control system having a centrally located user interface device, and distributed module-specific control subsystems, each having a dedicated module and being connected to the main electronic control system and to module-specific fault detectors of the dedicated module, and each of the module-specific control subsystems having a fault recovery-assist user interface device located at the dedicated module and remotely from the centrally located user interface device for providing in situ recovery-assistance for each the dedicated modules, and for enabling recovery-while-running isolation for a redundant dedicated module. |
