Abstract

In a reprographic system, it is a generally known practice to display system faults when recognized to allow an operator to rectify the fault situation and/or abort the job in progress. In addition, some systems employ a fault masking technique which allows the operator to mask the fault, thereby enabling only a limited subset of features that do not require the use of the faulted component. However, with the increased complexity and redundancy of features found in some reprographic systems it may be possible to substitute another similar feature, thereby avoiding clearing or masking the fault.

In a reprographic system, it is a generally known practice to display system faults when recognized to allow an operator to rectify the fault situation and/or abort the job in progress. In addition, some systems employ a fault masking technique which allows the operator to mask the fault, thereby enabling only a limited subset of features that do not require the use of the faulted component. However, with the increased complexity and redundancy of features found in some reprographic systems it may be possible to substitute another similar feature, thereby avoiding clearing or masking the fault.

Accordingly, the present invention automatically decouples a recognized faulted component from the remainder of the system. This allows the system to automatically utilize a redundant component in the place of the faulted component. As an example, if one of a plurality of paper feed trays indiates a faulted condition, the system may automatically switch to a non-faulted tray, containing the same paper stock, thereby continuing the job without the requirement of cycling down and clearing the fault. Furthermore, in this case, the operator would be free to clear the jam or fault while the job continues to completion. In general, the automatic fault masking feature of the Fresent invention would increase perfo...
