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.
Claims7
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.
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.
