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

1. 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.

2. The method of claim 1 wherein the second memory is a nonvolatile memory.

3. The method of claim 1 wherein the second memory is a a disc memory.

4. 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.

5. 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.

6. 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.

7. 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.
