Abstract
Abstract A technique for saving data related to given machine events in a control that normally records machine events or faults in a first-in, first-out buffer of finite size called an occurrence log by selectively setting the control to respond to the occurrence of a given machine fault or event, monitoring the operation of the machine for the occurrence of the given machine event, and initiating the transfer of the data in the buffer to a nonvolatile memory. Also included is the technique of delaying the transfer of the data in the buffer memory to the non-volatile memory until the recording of a given set number of events is determined in the buffer.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
A method of storing machine fault information including information indicating an occurrence of predetermined events in a reproduction machine having a plurality of components including a control with a first memory and a second memory, said method comprising the steps of: setting the control to respond to an occurrence of a predetermined event; setting said reproduction machine in a normal operation mode: capturing information on current faults and events of the reproduction machine and storing said data in the first memory; monitoring the operation of the machine in relation to said setting the control for the occurrence of the predetermined event; and upon recognizing the occurrence of the predetermined event, initiating a transfer of the information in the first memory to the second memory.
Claim 2
Independent Claim
124 words
A method of storing machine fault information including information indicating an occurrence of predetermined events in a reproduction machine having a plurality of components including a control with a first memory and a second memory, said method comprising the steps of: setting the control to respond to an occurrence of a predetermined event; setting said reproduction machine in a normal operation mode: capturing information on current faults and events of the reproduction machine and storing said data in the first memory; monitoring the operation of the machine in relation to said setting the control for the occurrence of the predetermined event; and upon recognizing the occurrence of the predetermined event, initiating a transfer of the information in the first memory to the second memory.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein the second memory is a nonvolatile memory.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein the second memory is a a disc memory.
Claim 5
Dependent Claim
41 words
The method of claim 1 wherein the step of initiating the transfer of data including the step of delaying the transfer of data until a predetermined number of events, after the occurrence of the predetermined event, is determined by the control.
Claim 6
Independent Claim
133 words
A method of storing machine fault information in a reproduction machine having a plurality of components including a control with an first memory for recording events and faults, a second memory, and an operator console, said method comprising the steps of: setting the control using the operator console to respond to an occurence of a predermined fault or a predetermined event; setting said reproduction machine in a normal operastion mode: capturing information on current events and faults of the reproduction machine and storing said information in the first memory; monitoring the operation of the machine for the occurrence of the predetermined fault or the predetermined event; and upon recognizing the occurence of the predetermined fault or the predetermined event, initiating the transfer of the information in the first memory to the second memory.
Claim 7
Independent Claim
133 words
A method of storing machine fault information in a reproduction machine having a plurality of components including a control with an first memory for recording events and faults, a second memory, and an operator console, said method comprising the steps of: setting the control using the operator console to respond to an occurence of a predermined fault or a predetermined event; setting said reproduction machine in a normal operastion mode: capturing information on current events and faults of the reproduction machine and storing said information in the first memory; monitoring the operation of the machine for the occurrence of the predetermined fault or the predetermined event; and upon recognizing the occurence of the predetermined fault or the predetermined event, initiating the transfer of the information in the first memory to the second memory.
Claim 8
Dependent Claim
38 words
The method of claim 5 wherein the step of setting the control using the operator console includes the step of displaying a set of perdetermined events or predetermined faults for selection by an operator on a display screen.
Claim 9
Dependent Claim
45 words
The method of claim 5 wherein the step of initiating the transfer of the data in the first memory to the second memory includes the step of delaying the transfer until a predetermined number of faults in the first memory is determined by the control.
