Abstract

Modern, high-speed reprographic systems generally employ complex and highly detailed operator interactive user interface screens, referred to as dialogue screens, to assist the customer through the complex tasks of job programming and fault recovery. Many of the faults are indicative of job programming errors or the presence of a shutdown condition which must be rectified before the job may proceed. To facilitate smooth and efficient operator recovery from these faults, each of the fault scenarios must be simulated and thoroughly tested prior to the release of the machine for sale. Unfortunately, the required testing may prove to be a difficult task due to the sheer number of fault scenarios that must be tested and the complex actions that are required to produce the unusual and uncommon fault scenarios. In order to properly accomplish such an immense verification task a fault exercise system must be employed.

FAULT SIMULATOR FOR A REPROGRAPHIC MACHINE(Cont'd)

Modern, high-speed reprographic systems generally employ complex and highly detailed operator interactive user interface screens, referred to as dialogue screens, to assist the customer through the complex tasks of job programming and fault recovery. Many of the faults are indicative of job programming errors or the presence of a shutdown condition which must be rectified before the job may proceed. To facilitate smooth and efficient operator recovery from these faults, each of the fault scenarios must be simulated and thoroughly tested prior to the release of the machine for sale. Unfortunately, the required testing may prove to be a difficult task due to the sheer number of fault scenarios that must be tested and the complex actions that are required to produce the unusual and uncommon fault scenarios. In order to properly accomplish such an immense verification task a fault exercise system must be employed.

Accordingly, the present disclosure is directed to a diagnostic tool that may be used in an electronic reprographic machine to induce the machine to simulate all attributes of any requested fault, including the behaviors of each fault and the operations which are required in order to remove the fault condition. The diagnostic...
