Abstract

A remote diagnostic system provides remote diagnostics for one or more facsimile apparatus. The system comprises facsimile, a communication control adapter and a personal computer (with expert knowledge). The system includes several kinds of data files which work under a window environment, together with communication software, to look up and rewrite the buffer memory in each facsimile.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a facsimile remote diagnostic system.

Facsimile is a well known technology which has been experiencing dramatic growth and usage in the business environment. Users recognize the inherent capability of facsimile as an effective means of transmitting many types of documents quickly and efficiently from a transmitting location to one or more remote receiving locations. Facsimile can quickly and efficiently transmit virtually any kind of document from one location to another in a very short transmission time, typically in seconds. This is a dramatic improvement over the sending of documents such as with the postal service and/or utilizing the various express courier services, which typically require overnight delivery of a document.

Users are demanding that the facsimile apparatus be readily available at virtually any time. Facsimile, however, can experience transmission and other types of problems, as with any type of communications equipment. It becomes increasingly important, therefore, to provide a diagnostic capability for the facsimile apparatus for a particular user(s). The facsimile apparatus is typically located at an office, and it becomes very inefficient for a user to have to rely on a diagnostic service to come to the particular office to make necessary repairs to the facsimile apparatus.

In addition, the diagnostic service necessarily increases the cost of the overall equipment, as that service must be paid for in repairing the facsimile equipment.

In other technologies, some approaches have utilized remote diagnostic systems. The first remote diagnostic system was introduced in general by computer makers to provide checks for the current and prior status of the computer system by running diagnostic programs.

The next sophisticated remote diagnostic system introduced a capability using what can be characterized as expert knowledge. However, only one such system or unit is generally not enough to support field-installed equipment. In a facsimile environment, the dramatic expansion can at times demand concurrent diagnostics.

In view of the foregoing, it would be very desirable to provide a remote diagnostic system which can provide remote diagnostics for one or more remotely located facsimile apparatus.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a facsimile remote diagnostic system.

Briefly, the facsimile remote diagnostic system according to the present invention comprises one or more facsimile apparatus connected to a conventional telephone line.

The system further includes remote diagnostic means for communicating with the facsimile apparatus. The remote diagnostic means includes software control means (in one preferred embodiment) for providing remote diagnostics for the facsimile apparatus, and communication adapter means for controlling communications between the software control means and the facsimile apparatus.

The software control means can provide suitable diagnostics for the facsimile apparatus from a remote location, thereby eliminating the need for service personnel to go to the particular location where the facsimile apparatus requires diagnostic services.

Other objects, features and advantages of the present invention will become apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

The remote diagnostic system according to the present invention provides remote diagnostics for one or more facsimile apparatus, such as those manufactured by the applicant, Ricoh Corporation. Reference will be made herein to several facsimile models of Ricoh Corporation, although the aspects of the present invention would apply to all types of facsimile.

The system 10 according to the present invention is shown in FIG. 1.

The system 10 comprises the following units: (1) one or more facsimile (FAX) 12, communication history of which is stored in memory accessible by remote way, (2) communication control adapter (CCA) 20 which can communicate with the FAX 12 and computer 50 through serial interface (RS232C) 22, and (3) personal computer 50 (including an expert system).

(1) Facsimile 12

The target facsimile is the G3 standard facsimile with the following additional functions: (a) buffer memory which can store communication histories including some image pattern, (b) bit switches which control the functions and mode by remote means, and (c) sensor status stored in the buffer memory.

(2) Communication Control Adapter 20

This unit has the same function as facsimile, network control unit (NCU), MODEM and protocol processor. Image communication with other FAX is possible. A block diagram of the CCA is shown in FIG. 2. FIG. 2 depicts a block diagram of the communication control adapter (CCA) 20. The CCA 20 includes a network control unit (NCU) 26 which controls data communication through a public telephone line 14. The main functions of the NCU 26 are startup of the unit, resetting or sendout of selected signals, calling signal detection and loop status maintenance (keep loop mode).

The CCA 20 also includes a modem 30 which provides data signal conversion to the transmission of analog signals and also provides the reverse inversions in a known fashion.

The CCA 20 further includes a multiple page signal controller (MPSC) 32 which detects the end of the page in image signal.

The CCA 20 also includes an operation port unit (OPU) 44 which controls the operation panel and keyboard.

Finally, the CCA 20 includes a power supply unit (PSU) 46 which provides suitable power as necessary.

CCA 20 has all the necessary functions of facsimile and digital interfaces to the PC 50 of FIG. 1. It can communicate with both current G3 facsimiles and computers and includes enough memory (RAM) 40 to store two-page document images.

(3) PC (Expert System) 40 This part is newly developed with architecture as seen in

FIG. 3. Details of the flow are shown in the accompanying Figures.

The main function flow of the FAX diagnostic system is shown in FIG. 4.

B Switch Setting

This function will allow the user to read all Bit Switch values from a remote FAX machine and then, if necessary, rewrite the new data back to the remote FAX machine. The Key is the customer name or customer FAX number. The screen will display as in FIG. 5.

B Switch Resetting

If Bit Switch values read from a remote FAX are not clear, this function will reset Bit Switch values for the remote FAX, based on the default values of the particular FAX model. After default values have been displayed on the screen, the user can modify any Bit Switch value and then rewrite all Bit Switch values back to remote FAX. The screen will display as FIG. 5. The only difference between these two functions is the former read data from remote FAX and the latter read data from Bit Switch default data base instead.

RAM Accessing

This function will allow the user to read a specific portion of RAM data from a remote FAX, and also easily modify those data on the screen and then rewrite the new data back to the remote FAX. The screen will display as in FIG. 6.

The RAM Definition window can have two displayed options:

(i) priority--display information on the screen started from the specified priority

(ii) address--display information on the screen started from the specified address

The user selects "Start Address" and "End Address" directly from the RAM Definition Table.

If the specified addresses are correct, the user clicks the "OK" button on the RAM Data Setting window. Then the system will start to access the remote RAM, and then display the retrieved data on the remote RAM Display window.

Users will be allowed to modify the data displayed on the remote RAM Display window (except for the Address column) and then, if necessary, the new data will be rewritten back to the remote FAX.

Reports

This function will supply various reports output, and allow the user to examine the important information through the screen display. The names of reports are:

TCR

Service Report

Transmission Report

Transfer Report

Error Report

System Report

Polling File List

Program List

How the System Works

FAX model is sometimes important to diagnose, because most knowledge is related to the model. In this example, FX3300 is stored in user's data base for initial communication setup. The customer's name is used as a key to connect the remote FAX. Another telephone number is necessary in case of FAX malfunctions.

Analyses results are reserved for future data analysis. The result of statistical analysis will be represented here.

"Line Fail," "CED Not Detected" and "DIS . . . " are the part of the stored expert knowledge listed in the manual. Tables 3 and 4 are the example already stored in Ricoh. The result of this diagnosis is service "ACTION." This should be connected to the small data base of service engineers. The result of the diagnosis will be sent to the customer or service center via FAX or phone (if FAX doesn't work).

Another window "DATA for FX3300" is connected to the specific data concerning FX3300. Tables 1 and 2 are the example.

A description of the operation of the facsimile diagnostic system according to the present invention will now be provided. In order to run the system, a user will need a configuration such as depicted in FIG. 1, which includes a control system such as a PC/AT,XT or IBM PS2 which runs DOS operating systems. In addition, a hard disk and a double sided disk drive is recommended. However, two double sided disk drives can be utilized. The user will need a serial cable, a communication control adapter (CCA), a mouse, an analog telephone line and two serial ports or a serial and a mouse port. The software is typically one such as Microsoft Windows version 2.0 or later version, and DOS 2.0 or later version.

The hardware interconnection is as depicted in FIG. 1, in which a telephone line is connected to the CCA socket, which indicates line side. The user connects a serial cable to both the CCA and computer serial port, and connects the mouse to the serial port or to a mouse port.

The "DTE/DCE" switch is set to "DCE". In starting up, the operation is as follows:

(1) Copy "*.*" to the windows' working directory.

(2) When in DOS, enter "WIN FAXSET" and then press <Return>, or

(3) Select and run FAXSET.EXE in the MS-DOS Executive window. Starting FAXSET automatically creates an empty window where the user can select various commands. Before running the program, Microsoft Windows are usually already installed.

The main menu on the display of PC of FIG. 1 is depicted in FIG. 21. In order to choose a Command from a Menu,

(1) if using the mouse, the user chooses a command from a menu:

(i) Click the menu name on the menu bar,

(ii) Click the command name.

(2) if using the keyboard, then follow these steps:

(i) press the ALT key,

(ii) press the underlined letter in the menu name,

(iii) press the underlined letter in the command name.

In order to cancel a menu,

(1) if using the mouse and decide after selecting the menu that the user doesn't want to choose a command, the menu can be cancelled by pressing ESCAPE.

2) if using the keyboard and decide after selecting the menu that the user doesn't want to choose a command, cancel the menu by clicking anywhere outside the menu. Clicking in a blank area of the window is best, so that the user doesn't select something else in the window without meaning to.

FIG. 22 depicts a RAM access menu on the display of the PC of FIG. 1.

In order to set up a communications port, the Set Comport command provides this function, as seen in FIG. 23. The user does this only if the port connection to CCA is different than default --COM1.

The user should use the mouse to select the right serial port which will communicate with CCA.

(i) Click "OK" to make some changes.

(ii) Click "CANCEL" if no changes or discard those changes.

FIG. 24 depicts the display of RAM accessing.

(1) If the user receives a message "Error in opening Com Port" after selecting RAM accessing command, then reset communications port.

(2) Input target fax telephone number to telephone number blank field.

(3) Input the starting and ending address of RAM where the user is going to retrieve data from target facsimile. If the command menu selected is "Read/Write BS" then input the starting and ending address of whole bit-switch-table basing on target machines' models For example, if target machine is R50 series, then

enter "0080" for starting address field, and

enter "009F" for ending address field.

(4) Click "OK" if input information is correct.

Then the application program will automatically dial the telephone number entered and retrieve the remote fax information which store in the RAM just entered above. If the RAM address specified is larger than 256 bytes, the application program will need to dial another call to get the rest of the data from remote target facsimile. But, the RAM accessing will not success if the telephone number entered is incorrect, the target facsimile is busy, the target facsimile does not power on, or CCA does not power on.

For each of these causes, the application program will pop up a related message on the screen. Here are some actions which should be followed:

(i) Reexamine the information entered on the screen.

(ii) Check the target facsimile's current status--power is off or machine is still busy.

(iii) Check CCA's connection and power switch.

(5) Click "CANCEL" if it is decided not to continue the program.

After data has been retrieved successfully from the target facsimile, the user needs to input data type for each address group. The window will display as seen in FIG. 25. For example, if retrieving the remote RAM from 70b0 to 70fa out of R50 series machines, the corresponding information will be TTI counter, TTI, CSI counter, CSI, RTI counter and RTI.

As defined, all three counters are HEX types and all three identifications are ASCII (upper case) types. Therefore, the input sequence will be as above table, which means:

______________________________________Address 70b0 stores a HEX data                    (TTI counter)Address from 70b1 to 70d0 stores ASCII                    {TTI}(upper) data.Address 70d1 stores a Hex data                    (CSI counter )Address from 70d2 to 70e5 stores ASCII                    (CSI)(upper) data.Address 70e6 stores a HEX data                    (RTI counter)Address from 70e7 to 70fa stores ASCII                    (RTI)(upper) data.______________________________________

Click "OK" if input information is correct, and click "CANCEL" if it is decided not to continue the application program.

RAM Data Display

After clicking "OK" on the "Data Type Table" window, the user can check the target facsimile information on the "Remote RAM Display" window as seen in FIG. 26. In this case,

______________________________________TTI counter    is 20 (HEX)TTI      is RICOH SAN JOSE ATD DEPARTMENTCSI counter    is 14 (HEX)CSI      is 94520637RTI counter    is 14 (HEX)RTI      is RICOH SAN JOSE BULD2______________________________________

If the user needs to rewrite the information displayed on the screen, follow these steps:

(1) Use mouse and click on that particular position

(2) Type in new data

(3) Click "WRITE" if the user wants to write the new data back to target facsimile

(4) Click "DONE" if all data has been examined

Since the maximum digits which can be entered for TTI is 20 (HEX), which is 32 (decimal), the user should not overtype new data to the next field, which will be a counter of CSI; also, the same as CSI, RTI, and some other similar cases.

If the size of retrieved data is larger than the size of the display window, the window will offer a vertical scroll bar on the right margin of the window. Then the user can use the scroll bar to review all of the data.

If the user needs to modify some data and rewrite back to target facsimile, then the application program will only rewrite those data which shows on the current window.

After data has been retrieved successfully from the target facsimile, the user can check the target facsimile Bit Switch information on the "Bit Switch Display" window in FIG. 27. If the user needs to rewrite the information displayed on the screen, follow these steps:

(1) Use mouse and click on that particular position.

(2) Type in new data.

(3) Click "WRITE" if the user wants to write the new data back to target facsimile.

(4) Click "DONE" if all the data has been examined.
