When the system is supplied with power source, the CPU 20 of the center facsimile device as shown in FIG. 1 checks whether or not the function performance key is pressed in step A1 of FIG. 2A. If an user (A/S worker) presses a predetermined key by the keyboard 10 for performance of remote-control function, whether remote control mode is established or not is checked in step A2. If the remote-control mode is established, step A3 is performed. In this case, since the remote-control function is authorized to A/S workers only, a password is given. In the step A3, input request of the telephone number of the remote facsimile device to be remote-controlled is made by displaying the request by the control of the display unit 50, and then step A4 is performed. In the step A4, whether telephone number is entered or not is checked. If the user finishes entering the telephone number using the keyboard 10, the input telephone number is stored in the telephone number region 12 of the internal memory having the regions as shown in FIG. 6B, and then step A5 is performed. In the step A5, the memory reading menu is displayed by the display unit 50. In step A6, whether or not the YES key is pressed is checked, and if the YES key is pressed, the memory reading routine is executed as shown in FIG. 3 by proceeding to A7, since it means that the user has chosen memory reading function. In this case, the YES key is pressed by the user by operating the keyboard 10 when the user wants to select memory reading function displayed by the display unit 50, and the NO key is pressed when other function is to be selected.
Accordingly, in step B1 of FIG. 3, address input request is displayed by the display unit 50 for the data stored in the memory of the remote facsimile device in which the user wants to read and verify, and in step B2, digits corresponding to the address pressed by the user using the keyboard 10 are displayed for verification by the user. In this case, the user presses the address in a specific number of digits by operating the keyboard 10 while verifying the state of the above display. In step B3, whether or not the YES key is pressed is checked, and if the YES key is pressed, that is if the user confirms the displayed address and presses the YES key on the keyboard 10, step B4 is performed. In the step B4, the size input request of the data to be read is displayed by the display unit 50. Furthermore, in step B5, the digits corresponding to the input size pressed by the user is displayed for the user's confirmation and step B6 is executed. In this case, the data size refers to the size of the data to be read starting from the address input. In the step B6, whether or not the YES key is pressed is checked, and if the YES key is pressed, that is when the user confirms the displayed address and presses the YES key by the keyboard 10, step B7 is executed. In the step B7, the data stored in the remote facsimile device is read by communicating in data format as shown in FIG. 6A according to the transmission controlling protocol shown in FIG. 5, after dialing the telephone number stored in the telephone number region 12 as shown in FIG. 6B through LIU 30. The data communication is conducted as illustrated in FIG. 5.
As stated above data communication is described with reference to FIG. 5. Firstly, when a call is made by dialing the remote facsimile device from the center facsimile device, the remote facsimile device sends non-standard facilities (hereinafter referred to as NSF) called subscriber identification (hereinafter referred to as CSI) plus digital identification signal (hereinafter referred to as DIS) to the center facsimile device. Then, for data communication, the center facsimile device confirms the line connection acknowledgment and requests data by sending non-standard facilities command (hereinafter referred to as NSC) including request command and data to the remote facsimile device, and the remote facsimile device sends NSC including acknowledgment command and data to the center facsimile device. After receiving this data, the center facsimile device sends disconnect (hereinafter referred to as DCN) to the remote facsimile device when all data is correct after verification so as to request for switching communication lines, and then the remote facsimile device switches communication line to complete the communication. The communication data is modulated and demodulated by the modem 40. The result of the data reading according to the data communication described in the foregoing is stored in the performance result storing region 13 of the internal memory shown in FIG. 6B. In the step B8, the memory reading function performance result which is stored in the performance result storing region 13 of the internal memory as shown in FIG. 6B is converted to data ready to be printed on paper. The converted data is stored in the print data region 14 as shown in FIG. 6B. The converted and stored print data is applied to the recording unit 60 and then the process ends after printing the print data on a paper with certain format to allow the user to verify the result. The paper changes according to a selected printing method, and if the center facsimile device uses a thermal print head (T.P.H), it uses thermal sensitive paper for printing.
Meanwhile, if the YES key is not pressed in the step A6, the NO key input is checked in step A8. If the NO key is pressed in the step A8, step A9 is performed and a memory writing menu is displayed by the display unit 50. In step A10, whether or not the YES key is pressed is checked, and if it is pressed, step A11 is performed for executing the memory writing routine shown in FIG. 4, since the user selects the memory writing function for changing the data stored in the memory of the remote facsimile device.
Accordingly, in step C1 of FIG. 4, the user displays through the display unit 50, the input request of an assigned address for the memory of the remote facsimile device that the user wants to write the changed data in, and digits of the address which is pressed by the user by operating the keyboard 10 to allow verification by the user is displayed in step C2. In step C3, whether or not the YES key is pressed is checked, and if it is pressed, that is if the user confirms the displayed address and presses the YES key on the keyboard 10, the data input request of the data to be written is displayed by the display unit 50 in step C4. In step C5, the digits corresponding to the input data pressed by the user is displayed for the user's confirmation and step C6 is executed. In the step C6, whether or not the YES key is pressed is checked, and if it is pressed, that is if the user confirms the displayed data and presses the YES key on the keyboard 10, data for the next address is entered by returning to step C1 and repeating the foregoing procedure. Therefore, all the data and address to be written is entered. In the step C7, if the YES key is not pressed in the step C6, it is determined whether or not the NO key is pressed. When the NO key is pressed in the step C7, that is if the user presses the NO key on the keyboard 10 after completing the data input, step C8 is performed. In the step C8, the data stored in the remote facsimile device is changed by communicating in data format as shown in FIG. 6A according to the transmission controlling protocol shown in FIG. 5, after dialing the telephone number of the remote facsimile device stored in the telephone number region 12 as shown in FIG. 6B through LIU 30. In this case, the data communication is conducted in the same way as described in the memory reading process. After storing the result of data writing through data communication as in the performance result storing region 13 of the internal memory as shown in FIG. 6B, step C9 is performed. In the step C9, the result of the memory writing performance stored in the above performance result storing region 13 is printed in the same manner as described in the memory reading process, and the process ends.
Meanwhile, if the YES key is not pressed in step A10, the NO key input is checked in step A12, and if the NO key is pressed, the remote diagnosis menu is displayed by the display unit 50 by proceeding to step A13. In step A14, whether or not the YES key is pressed is checked, and if it is pressed, the user may select the remote diagnosis mode to diagnose the state of the remote facsimile device. Step A15 is performed for diagnosing the state of devices such as read-only memory, random access memory and lamp of the remote facsimile device according to the key input of the user, and the process ends after printing the result. In order to remotely diagnose, the process of data communication and printing is conducted in the same manner as described in the memory reading process. Here, the distinction of the result of the diagnosis can be made by identifying the data in the data format such that when the data is 00, it can be identified as being normal and when the data is OFFH, it can be identified as malfunction.
If the YES key is not pressed in the step A14, the NO key input is checked in the step A15 and if the NO key is pressed, step A17 is performed and a name registration menu is displayed by the display unit 50. In step A18, whether or not the YES key is pressed is checked, and if it is pressed, the user may select the name registration function for registering the name of the host machine type, so step A19 is performed for registering the name data inputted to the TTI region 11 which corresponds to the telephone number of the remote facsimile device stored in the telephone number region 12 as shown in FIG. 6B according to the key input of the user, and the process ends after sending the name data to the remote facsimile device and printing the result. Here, the process of data communication and printing for registering name is conducted in the same manner as described in the memory reading process.
If the YES key is not pressed in the step A18, the NO key input is checked in step A20 and if the NO key is pressed, step A21 is performed and the telephone number registration menu is displayed by the display unit 50. And in step A22, whether or not the YES key is pressed is checked, and if it is pressed, the user may select the telephone number registration function for registering the telephone number of the host machine type, so step A23 is performed for registering the telephone number data inputted to the TTI region 11 which corresponds to the telephone number of the remote facsimile device stored in the telephone number region 12 as shown in FIG. 6B according to the key input of the user, and the process ends after sending the telephone number to the remote facsimile device and printing the result. Here, the process of data communication and printing for registering the telephone number is conducted in the same manner as described in the memory reading process.
If the YES key is not pressed in the step A22, the NO key input is checked in step A24 and if the NO key is pressed, step A25 is performed and the option reading menu is displayed by the display unit 50. In step A26, whether or not the YES key is pressed is checked, and if it is pressed, the user may select the option reading menu for checking the state of various optional function settings of the remote facsimile device, so step A27 is performed for reading various optional function setting data according to the key input of the user, and the process ends after printing the result. The process of data communication and printing for reading the option data is conducted in the same manner as described in the memory reading process. The printing of the option result is done so that the user can easily read the result for each optional function item. If the YES key is not pressed in the step A26, the NO key input is checked in step A28 and if the NO key is pressed in the step A28, the process proceeds to step the A5 for repeating the procedures described in the foregoing.
In each of the procedures described in the foregoing, the input of the keys on the keyboard 10 which can be pressed by the user (A/S worker) is the alphabet from A to Z, arabic numbers from 0 to 9, and inputs of * and # etc.
Meanwhile, the supply of low-cost facsimile devices having no LCD windows is expected to increase rapidly by looking at the current trend, and by accordingly performing the remote-control function as described in the foregoing, service cost and time can be effectively reduced and A/S claim due to mishandling of the facsimile devices by users can be minimized.
As described in the foregoing, the present invention provides a method for interactively diagnosing and controlling the state of remote facsimile devices by the facsimile devices of A/S centers, by data communicating with the remote facsimiles using non-standard format recommended by CCITT regulation, thus an advantage is reducing A/S cost and the time spent. Another advantage is solving general problems concerning A/S by just one phone call, and printing on paper each result according to the type of remote-control for easy identification to perform effective A/S.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that modifications in detail may be made without departing from the spirit and scope of the invention.
