## Title
Method and system for providing technical support documents via the internet

## Abstract

A method for providing technical support documents on a peripheral device connected to a web server storing the requested technical support documents via the Internet, which includes the steps of selecting an event on the device, requesting a default uniform resource locator with the selected event, and returning the technical support document relating to the selected event of the requested uniform resource locator to the device.

## Background
The present invention generally relates to an improved method and system for providing technical support documents via the Internet. More specifically, it relates to an improved method and system for providing technical support documents via the Internet on a peripheral device connected to a web server storing the requested technical support documents.
BACKGROUND OF THE INVENTION
Currently, the technical support documents of peripheral devices, such as printers, are generally included on a CD Rom. The control panel of the peripheral device provides some control panel messages, which tend to be very short messages. As a result, they are usually not very informative or helpful. However, these messages tend to be shorter because they are generally stored in the firmware of the peripheral device. Firmware, which is generally used for peripheral devices, is software responsible for the operations of the device, and it is stored in read-only memory (ROM) or programmable ROM (PROM). However, the storage capacity of the ROM tends to be very limited. Users are, then, forced to access the technical support document located on CD Rom for troubleshooting solutions when confronted with an error message displayed on the device.
The problem with this prior method is that it is not always clear to the user which technical support documents are relevant for a given error or control panel message. This is especially true for typical users. Users generally do not have the technical background needed to make such a determination. Consequently, it would be extremely helpful and desirable if the peripheral device itself can provide users with the relevant technical support document for each particular error message displayed. There is obviously a need for an improved method that can provide more direct technical support from the actual peripheral device.
BRIEF SUMMARY OF THE INVENTION
The present invention is directed to an improved method and system for providing technical support documents via the Internet. More specifically, it relates to an improved method and system for providing technical support documents via the Internet on a peripheral device connected to a web server storing the requested technical support documents.
The present invention provides a method that includes the steps of selecting an event on the device, requesting a default uniform resource locator (“URL”) for the selected event, and returning the technical support document relating to the selected event of the requested uniform resource locator to the device.
The present invention further provides a system that includes a peripheral device for requesting technical support documents of a selected event using a default URL, and a web server for servicing the default uniform resource locator by returning the relevant technical support document that relates to the selected event.

DETAILED DESCRIPTION
Broadly stated, the present invention is directed to an improved method and system for providing technical support documents over the Internet. The method and system provide a way to provide the relevant technical documents for a displayed error message straight on the peripheral device. Aside from providing context sensitive technical support documents to users, the present invention also allows users to access a help menu from the peripheral device for obtaining the needed technical support documents.
An event is first selected either through the help menu or context sensitive table for a particular displayed error message. Then, a default URL is requested with the selected event. Consequently, a technical support document (“TSD”) relating to the selected event is returned to the peripheral device. It should be understood that the use of “a” or “an” is also intended to mean “one or more” for better readability.
Turning now to the drawings, and particularly FIG. 1, a schematic diagram of a network system in which the present method can be implemented is shown and indicated generally at 10. A web server computer 12 is shown to be connected to a peripheral device 14, for example a printer, connected via the Internet 16. The peripheral device preferably contains the web client, device state table, firmware and the default URL for accessing the TSD's. The device state table 20 includes a list of the events that have been logged by the device, and these events are predefined by significant occurrences or happenings of the device.
The web server computer 12, on the other hand, services the default URL 24 included in the firmware 22 of the peripheral device 14. A number of TSDs 26 are made available to the peripheral device 14 by the web server computer 12 when requested. Although a single web server computer 12 and peripheral device 14 are shown, as is known in the art, multiple web server computers can be used for servicing a URL. Furthermore, in the actual implementation, a great number of peripheral devices 14 are preferably connected to the web server computer 12. Because the network system needed for the implementation of the present invention can vary greatly in complexity and size, the network topology shown in FIG. 1 is given as an example. Other network systems for implementing the present invention are contemplated and are within the scope of the present invention.
Turning to an important aspect of the preferred embodiment of the present invention, a flow chart of the preferred functionality of a method is shown in FIG. 2, and indicated generally at 30. The method is initiated by a user pushing HELP on the peripheral device (block 32). The HELP button on the peripheral device is the preferred dedicated switch to initialize the device to start the method to request a technical support document. However, other implementations of the dedicated switch can be used. For example, as the control panel display becomes larger and more sophisticated, an icon on the display may be available to users instead of a push button. Other implementations of the dedicated switch are contemplated and are within the scope of the present invention.
The device first reads the device state table (block 34) and obtains the most recently activated event that is to be selected as the selected event (block 36). Furthermore, the device also obtains a default URL from the firmware (block 38), which will be used later to request the TSD once the event selection has been finalized. It is next determined whether a display is available on the peripheral device (block 40). If a display is not available (block 40), the device, using its embedded web client, continues by requesting the default URL with the selected event (block 42), which is the most recently activated event in this case. The most recently activated event is automatically selected by the method, because the user cannot select another event through the help menu on the peripheral device without the display being available.
If, on the other hand, a display is available on the peripheral device (block 40), it is next determined whether the most recently activated event obtained from the device state table indicates an error (block 44). If the most recently activated event does indicate an error (block 44), the device is preferably configured to again request the default URL with the selected most recently activated event (block 42). From this configuration, the peripheral device is able to return a context sensitive TSD to the user. In other words, since the device requests a TSD related to the error event, only the relevant TSD will be returned to the user.
However, if the most recently activated event is not an error (block 44), the device is configured to request the default URL without a selected event (block 46). Because a selected event was not included with the request for the default URL (block 46), the web server computer 12, in response, returns a help menu (block 48). The help menu is then displayed to the user (block 50), and the user can then accordingly select another event from the menu (block 52). A request for the default URL with the selected event will again be sent to the web server computer (block 42). In the preferred embodiment, the help menu is located on the web server computer, and a request for the default URL without a selected event will prompt the web server computer to return a help menu. However, other implementations can be used, such as storing the help menu with the firmware on the device. In this case, when a request for the default URL is prompted without a selected event, the device can be configured to automatically return the help menu on the display. There may be other implementations with slight modifications, however these various implementations are contemplated and are within the scope of the present invention.
Once the selected event is obtained, either from the device state table (block 36) or from the user help menu (block 52), a request for the default URL with the selected event is made upon the web server computer (block 42), which prompts it to return a TSD relating to the selected event (block 54). After receiving the TSD (block 54), the device reads the device configuration from the firmware (block 56) to determine whether the TSD should be printed or displayed (block 58). Accordingly, the TSD is printed (block 60) or displayed (block 62) to the user, depending on the device configuration. In peripheral devices without a display, the device configuration can only be defined to print the TSD. However, for the peripheral devices with a display, it is contemplated that users can select the default device configuration to print or display the TSD.
Because the functionalities of each peripheral device can vary greatly, the preferred method can also be altered as a result. It is contemplated that the present method can be changed to accommodate different devices and their particular models as well. As a result, it should be understood that these other methods are within the scope of the present invention.
An example of control panel messages when the HELP button is pressed on the peripheral device when there is no error condition is shown in FIG. 3 and indicated generally at 70. More specifically, FIG. 3 shows an example of the help menu that can be displayed to users when the most recently activated event from the device state table is not an error. From this help menu, users can choose an event or a topic for requesting a TSD from the web server computer. For this particular example, the peripheral device is a printer with a display control panel. Consequently, the events are configured and designed to fit the printer. However, the present invention can also work with any type of peripheral devices, such as a scanner or a fax machine. The help menu can vary as a result. Because the display on the control panel is generally small in size, typically only two to three lines can be displayed at a time. In this example, the dashed line is to indicated when users must scrolled down to see the next message.
Turning to another example, an exemplary display of the control panel messages of a printer when the HELP button is pressed on an error message of “COLOR TONER LOW” is shown in FIG. 4 and indicated generally at 80. In this scenario, a printer is displaying a “COLOR TONER LOW ?” message on the control panel. A user presses the help button on the printer, which prompts the device to display the panel messages shown in FIG. 4. In this particular example, the user can select to print the help document (i.e., TSD) from the web. If selected, the device sends a URL request with the event defining the “COLOR TONER LOW” message to the web server computer 12, and a TSD relating to that event will be printed on the device.
An example of a technical support document that can be displayed or printed on the peripheral device is shown in FIG. 5. As shown, the TSD provides a detailed description to solve a particular problem, specially an error when printer will not pull paper from a particular tray. However, in this example of the TSD, no figures are shown. But, since the capacity of the memory storage is no longer a major concern, figures for user friendly instructions can be included for clarity.
Because the TSDs are stored on the web server computer, very extensive and informative documents can be provided to users. This is so because the limited memory storage of the ROM is no longer being used for storing the TSDs for the peripheral device. But at the same time, the web server computer is able to return the TSD that is most relevant to an error that the device might be experiencing. Furthermore, since the TSDs needed are stored on the web server computer, any updates or changes can easily be accomplished at one central location for devices that were sold throughout the world.
From the foregoing description, it should be understood that an improved method and system for providing technical support documents via the Internet has been shown and described, which has many desirable attributes and advantages. The method and system provide a way for users to easily obtain context sensitive or requested technical support documents via the Internet. As a result of these documents being stored on a web server computer outside of the peripheral device, extensive and informative graphical technical support documents can be provided to users. Furthermore, because the present invention provides for a central location to obtain these documents, any updating or changing of these documents can be easily achieved with fewer efforts.
While various embodiments of the present invention have been shown and described, it should be understood that other modifications, substitutions and alternatives are apparent to one of ordinary skill in the art. Such modifications, substitutions and alternatives can be made without departing from the spirit and scope of the invention, which should be determined from the appended claims.
Various features of the invention are set forth in the appended claims.
