Abstract

A printer service tool includes a control panel port connector for connecting to the control panel port of a printer, a controller diagnostic port connector for connecting to a diagnostic port of the printer, and a display. The display displays a plurality of menus. A first menu includes a representation of buttons displayed on a control panel of the printer. A second menu includes menu items which provides ability to monitor printer functionality.

Claims

1. A printer service tool, comprising:

a control panel port connector for connecting to a control panel port of a printer;

a controller diagnostic port connector for connecting to a diagnostic port of the printer; and

,

a single display by which is displayed a plurality of menus, the plurality of menus including;

a first menu that includes a representation of buttons displayed on a control panel of the printer, the representation of buttons being displayed by the single display, and

a second menu that includes menu items, the menu items providing ability to monitor printer functionality.

2. A printer service tool, as in claim 1 wherein the plurality of menus additionally comprises a third menu that includes a representation of buttons displayed on a control panel of a second type of printer, the second type of printer being of a different type than the printer from the control panel of which the first menu includes menu items.

3. A printer service tool, as in claim 1 wherein the second menu includes menu items from an engine test menu.

4. A printer service tool, as in claim 1 wherein the second menu includes menu items that allow selection of a paper path through the printer.

5. A printer service tool, as in claim 1 wherein the second menu includes an indication of the fuser temperature for the printer.

6. A printer service tool, as in claim 1, additionally comprising a port connector for connecting the printer service tool to an external computing device, the printer service tool transferring to the external computing device, through the port connector, service information obtained from the printer.

7. A printer service tool as in claim 1 wherein the first menu includes an explanation of any errors captured from the controller diagnostic port.

8. A method for providing service to a printer, the method comprising the following steps:

(a) connecting the printer to a printer service tool;

(b) selecting, by a user of the printer service tool, a first macro to be performed at start-up of the printer; and

,

(c) simulating, by the printer service tool upon the printer service tool detecting start-up of the printer, button presses on a control panel for the printer, including the following substeps;

(c.1) setting button values for the control panel, and

(c.2) holding the button values for a predetermined amount of time.

9. A method as in claim 8 wherein in step (b) the first macro places the printer into a service mode.

10. A method as in claim 8 wherein in step (b) the first macro places the printer into an extended diagnostics mode.

11. A method by which a printer service tool provides service to a printer, the method comprising the following step:

(a) in response to a user of the printer service tool selecting a first macro to be performed at start-up of the printer, simulating, by the printer service tool upon the printer service tool detecting start-up of the printer, button presses on a control panel for the printer, including the following substeps;

(a.1) setting button values for the control panel, and

(a.2) holding the button values for a predetermined amount of time.

12. A method as in claim 11 wherein in step (b) the first macro places the printer into a service mode.

13. A method as in claim 11 wherein in step (b) the first macro places the printer into an extended diagnostics mode.

14. A printer service tool, comprising:

a control panel port connector for connecting to the control panel port of a printer;

a controller diagnostic port connector for connecting to a diagnostic test port of the printer; and

,

a port connector for connecting the printer service tool to an external computing device so that the printer service tool is simultaneously connected to the printer and the external computing device, the printer service tool transferring to the external computing device, through the port connector, service information obtained from the printer;

wherein the control panel port and the diagnostic test port are separate printer ports which are not connected to each other during normal operation of the printer.

15. A printer service tool as in claim 14, additionally comprising:

software, running on the external computing device, the software receiving current contents of a control panel display of the printer 11 and displaying detailed information about any messages and errors indicated by the current contents of the control panel display.

16. A printer service tool as in claim 15 wherein the detailed information includes information about any failure in printer operation and includes a suggested fix.

17. A printer service tool as in claim 15 wherein the software includes a web browser to be used for updating the detailed information from a remote web site.

18. A method for providing service via a printer service tool, comprising the following steps:

(a) connecting the printer service tool to a printer including connecting the printer service tool to both a control panel port of the printer and connecting the printer service tool to a diagnostic test port of the printer, the control panel port and the diagnostic test port being two separate ports of the printer which are not connected to each other during normal operation of the printer;

(b) connecting to the printer service tool an external computing device, so that the printer service tool is simultaneously connected to the printer and the external computing device;

(c) obtaining, by the printer service tool from the printer, service information pertaining to the printer; and

,

(d) transferring, by the printer service tool to the external computing device, service information obtained from the printer.

19. A method as in claim 18 additionally comprising the following step:

(e) displaying, by the external computing device, detailed information about any messages and errors indicated by current contents of a control panel display of the printer, the current contents of the control panel display of the printer being included as part of the service information obtained from the printer in step (d).

20. A method as in claim 19 wherein in step (e) the detailed information includes information about any failure in printer operation and includes a suggested fix.

21. A printer service tool as in claim 19 additionally comprising the following step:

(f) updating the detailed information from a remote web site.
