Abstract: One aspect of the disclosure is directed to a calibration system. The calibration system includes an imaging device including a predetermined print engine capable of being calibrated and a calibration sheet. The calibration sheet includes at least one visible calibration reference region including a given mix of pre-selected reference colorants printed in the calibration reference region on the calibration sheet. The pre-selected reference colorants have been previously printed on the printable calibration sheet using a different imaging device that is different than the given imaging device and that has the same print engine as the given imaging device. The calibration sheet includes freshly printable target regions on the calibration sheet. The given imaging device is configured to enter into the calibration mode, wherein the given imaging device is configured to freshly print a mix of colorants corresponding to the pre-selected reference colorants onto at least one of the target regions.

Abstract: A calibration system includes a printer capable of being calibrated and a printable calibration sheet. The printable calibration sheet includes at least one calibration reference segment printed on the sheet and one or more defined printing spaces on the sheet. The at least one calibration reference segment includes one or more pre-selected colorants on the printable sheet. The one or more defined printing spaces are adjacent to the at least one calibration reference segment. The one or more defined printing spaces are arranged to accept printing of a color pattern from a printer under calibration.

Abstract: A method of use of real time machine control software integrating both event based mode and task based components. In particular, a collection of constructs have been created that allow machine control applications to be expressed in event based terms and the event based constructs to be seamlessly integrated with task based constructs. The method includes the use of response time specifications, in particular in conjunction with ReactiveTask and Task constructs. The method also includes the use of Register, ReferenceClock, and SchedulerLock constructs.

Abstract: The method of verifying the integrity of the non-volatile memory device contents in an image processing apparatus having image processing for forming an image, a controller for directing the operation of the image processing, a mass memory device and a non-volatile memory device for dynamically storing critical machine data comprising the steps of performing a non-volatile memory check including the steps of verifying selected patterns and verifying a checksum related to the non-volatile memory, determining a non-volatile memory fault during the process of performing the non-volatile memory check, retrieving backup critical machine data from the mass memory device, storing the critical machine data into the non-volatile memory device, and providing dynamically updated data backup of the non-volatile memory image to the mass memory device.

Abstract: System for recording and remotely accessing certain operating data in an electrostatographic reproduction machine for use in analyzing machine faults and software crashes, with transfer of the data to a remote service site either by floppy disk or telecommunications line.

Abstract: A method of resetting an arbitrary node or input/output board in response to a control communications fault in said arbitrary node or input/output board during a real time job in an image processing apparatus having image processing means for forming an image, a controller including a plurality of nodes connected to a plurality of input/output boards and software including an application portion and a communication portion, comprising the steps of the arbitrary node or input/output board initiating a self reset independent of any other node or input/output board reset, the remaining nodes or input/output boards refraining from initiating a reset of the node or input/output board, resetting said arbitrary node or input/output board independent of said remaining nodes or input/output boards, and continuing operation of said arbitrary node or input/output board to complete the real time job run.
