Internal expert system to aid in servicing

Claim 2

In a printing system having a machine with a plurality of operating components, a control and an expert system, the control cooperating with the operating components to produce images on copy sheets, the expert system monitoring predetermined status conditions of the machine for automatic correction or for communication to the operator, the method of the machine monitoring the status conditions and initiating communication relative to the status conditions of the machine comprising the steps of: monitoring with the expert system said predetermined status conditions relative to the operation of the machine, recognizing the deviation of the machine operation from said predetermined status conditions, responding to the deviation of the machine operation from said predetermined status conditions, and optionally automatically correcting the machine to return the machine to standard operation, or initiating an interactive dialogue with the operator to return the machine to standard operation including the step of requesting operator input of relevant data.

Claim 3

The method of claim 1 wherein the control provides status points related to the operating components and the step of monitoring with the expert system said predetermined status conditions relative to the operation of the machine includes the step of determining a variation of the status points from a threshold level.

Claim 4

The method of claim 2 wherein the step of determining the variation of the status points from a threshold level includes the step of calculating a value in accordance with a given equation related to the status points.

Claim 5

The method of claim 3 including the step of adjusting selected operating components of said machine from said expert system.

Claim 6

In a printing system having a machine with a plurality of operating components for producing image impressions on image bearing members, a control cooperating with the operating components to produce the images on the image bearing members, and an expert system, the expert system including memory with the profile of expected machine performance and parameters portion, a current switch and sensor information portion, and a table of historical machine performance and utilization events, the method of the machine monitoring status conditions and initiating external communication relative to the status conditions of the machine comprising the steps of: monitoring said predetermined status conditions relative to the operation of the machine, recognizing the deviation of the machine operation from said predetermined status conditions, recognizing the inability of the machine to automatically respond to the deviation to self correct, determining the need for external response to provide additional information for evaluation for further analysis, requesting said additional information for evaluation for further analysis, and upon receipt of said additional information, determining the correct response to return the machine operation to a mode not in deviation from said predetermined status conditions, and automatically providing the correct response to return the machine operation to a mode not in deviation from said predetermined status conditions.

Claim 7

In a printing system having a machine with a plurality of operating components for producing image impressions on image bearing members, a control cooperating with the operating components to produce the images on the image bearing members, and an expert system, the expert system including memory with the profile of expected machine performance and parameters portion, a current switch and sensor information portion, and a table of historical machine performance and utilization events, the method of the machine monitoring status conditions and initiating external communication relative to the status conditions of the machine comprising the steps of: monitoring said predetermined status conditions relative to the operation of the machine, recognizing the deviation of the machine operation from said predetermined status conditions, recognizing the inability of the machine to automatically respond to the deviation to self correct, determining the need for external response to provide additional information for evaluation for further analysis, requesting said additional information for evaluation for further analysis, and upon receipt of said additional information, determining the correct response to return the machine operation to a mode not in deviation from said predetermined status conditions, and automatically providing the correct response to return the machine operation to a mode not in deviation from said predetermined status conditions.
