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.
