Abstract

A technique for problem analysis to diagnose a declared machine fault of a suspected machine fault in a reproduction machine having a control with a touch operative user interface and screen display including the steps of placing the machine in a service mode and entering a fault analysis mode to allow access to a library of fault analysis information, providing the option of troubleshooting the declared machine fault by entering into the control a displayed first fault code, or selecting from a group of categories generally describing a problem area to trouble shoot the suspected machine fault including the steps of selecting one of the group of categories to display a plurality of potential defects related to the selected category in icons and/or text including an associated second fault code, matching one of the displayed plurality of potential defects with the suspected machine fault and entering into the control the associated second fault code, and displaying troubleshooting information related to the second fault code.

Claims

1. In a reproduction machine having a plurality of interactive machine components cooperable to produce copies from document originals including a control having a touch operative user interface and screen display, a self contained method of problem analysis comprising the steps of:

entering into a problem analysis mode in the machine,

providing a portion of the display to manifest a fault code if a machine fault actually exists,

displaying a first plurality of system indicators related to suspected machine problems,

touch entering into the control via the user interface a fault code number, if a fault code is manifested in said portion of the display, or

touch activating one of the, system indicators and

displaying a second plurality of system indicators related to said one of the systems indicators the second plurality of system indicators providing visual representations to identify said suspected machine problem.

2. In a reproduction machine having a plurality of interactive machine components cooperable to produce copies from document originals including a control having a touch operative user interface and screen display, a method of identifying a non-detected machine fault comprising the steps of:

displaying on a first screen illustration a plurality of indicators related to the interactive machine components,

selecting one of the indicators, the indicator identifying a given interactive component and

displaying on a second screen illustration a visual likeness of a plurality of possible malfunctions related to said given interactive component identified by said indicator, each visual likeness having an associated code, and

selecting one of said codes to display corrective information on a third screen illustration related to said given interactive component.

3. The method of claim 2 wherein the step of selecting one of said codes to display corrective information on a third screen illustration related to said given interactive component includes the step of displaying a definition of the fault and description of the conditions that cause it, discrete component checks and associated on-board diagnostic checks, or recommendations for parts adjustment or replacement.

4. In a reproduction machine having a plurality of interactive machine components cooperable to produce copies from document originals including a control having a touch operative user interface and screen display, a self contained method of problem analysis to diagnose a declared machine fault or a suspected machine fault comprising the steps of:

placing the machine in a service mode,

entering a fault analysis mode to allow access to a library of fault analysis information,

providing the option of troubleshooting the declared machine fault by entering into the control a displayed first fault code, or

selecting from a group of categories generally describing a problem area to trouble shoot the non-declared machine fault including the steps of;

selecting one of the group of categories to display a plurality of undetectable defects related to the selected category including an associated second fault code,

matching one of the displayed plurality of potential or undetected defects with the suspected machine fault and entering into the control the associated second fault code, and

displaying troubleshooting information related to the second fault code.

5. The method of claim 4 wherein the step of displaying troubleshooting information related to the second fault code includes the step of displaying a definition of the fault and description of the conditions that cause it, discrete component checks and associated on-board diagnostic checks, or recommendations for parts adjustment or replacement.

6. In a reproduction machine having a plurality of interactive machine components cooperable to produce copies from document originals including a control having a user interface and screen display, a self contained method of analysis of non-detected machine faults comprising the steps of:

entering into a problem analysis mode in the machine,

displaying a plurality of sub-system indicators related to non-detected machine faults,

activating one of the sub-system indicators, and

displaying a plurality of non-detected machine fault situations related to said one of the sub-system indicators.

7. The machine of claim of claim 6 wherein the sub-system indicators are icons on the screen display.

8. In a reproduction machine having a plurality of interactive machine components cooperable to produce copies from document originals including a control having a user interface and screen display, a self contained method of problem analysis comprising the steps of:

entering into a problem analysis mode in the machine,

providing a portion of the display to manifest a fault code if there is a declared machine fault,

displaying a plurality of sub-system indicators related to non-declared machine problems, and

visually representing a plurality of non-declared machine fault situations related to said one of the sub-system indicators to identify the non-declared fault situation.

9. In a reproduction machine having a plurality of interactive machine components cooperable to produce copies from document originals including a control having a user interface and screen display, a self contained method of problem analysis comprising the steps of:

entering into a problem analysis mode in the machine,

providing a portion of the display to manifest a fault code if a machine fault actually exists,

displaying a first plurality of system indicators related to non-detected machine problems,

activating one of the system indicators and

displaying a second plurality of system indicators related to said one of the system indicators the second plurality of system indicators providing visual representations to identify said non-detected machine problem.
