Abstract

PURPOSE:To enable diagnosis of an isolated facsimile device with no operation of the operator, by providing a function of remote diagnosis to a non-standard signal produced by a facsimile device. CONSTITUTION:A control part 13 of a facsimile device 1 having a set indication for remote diagnosis produces and transmits a non-standard device setting signal indicating to decode a diagnosis data to be given later to a facsimile device 2 and stores it temporarily. Then the part 13 transmits the diagnosis data stored in a data storing part 15. This diagnosis data is received at the device 2 and stored in a data storing part 25. Then the device 1 transmits a non-standard device instruction indicating to send the diagnosis data stored in the part 25 back to the device as it is. Receiving this instruction, the device 2 transmits a diagnosis result data to the device 1. This result data is then transferred to the part 15 of the device 1. The part 13 of the device 1 compares the diagnosis data which is sent first to the device 2 with the sent-back data, and displays it.

Description

[Detailed description of the invention] The present invention relates to a method for diagnosing a facsimile machine.

In the conventional facsimile device diagnosis method, an operator operates the device to be diagnosed to execute the diagnostic function of the device to determine whether the device is good or bad, in order to diagnose whether there is a malfunction in the facsimile device, etc. .

As one method for diagnosing facsimile devices, when diagnosing the encoding and decoding functions related to redundancy suppression of facsimile data, the document information set in the transmitter of the device to be diagnosed is encoded, and the encoded information is The received information is returned to the reception section of the own device, the returned encoded data is decoded, the result is obtained as a recording surface, and the operator searches for the presence or absence of errors on the recording surface, and performs the aforementioned encoding and decoding functions. The method for diagnosing whether or not the am is normal is based on the fault report from the user, etc., and the maintenance person has to go to the user's place and directly operate the diagnosed am. The disadvantage was that he had to ask for instructions from the primary male.

Furthermore, with regard to the encoding and decoding functions, the operator compares the original and the recording surface and determines the quality of the functions by finding differences between them, which has the disadvantage that a reliable diagnosis cannot be made.

The object of the present invention has been made to eliminate the above-mentioned drawbacks inherent in the prior art, and to provide a remote facsimile*
mt, an object of the present invention is to provide a method for diagnosing a facsimile device, which can diagnose the device without any operation by the operator of the device, and easily and reliably obtain the results.

It is configured to have both terms 1) and (2).

Next, embodiments of the present invention will be described with reference to five drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

A preferred embodiment of the facsimile device diagnosis method according to the present invention will be described in detail.

The facsimile device diagnosis method shown in Figure 1 is based on the international standard standard recommended by CCITT as a remote diagnosis procedure.
, in accordance with the procedures specified in Article 30.

By using non-standard signals allowed in the standard, remote diagnosis is realized without interfering with normal facsimile communications.

In FIG. 1, it is assumed that an operator remotely diagnoses a facsimile machine 1 and a facsimile machine 2 which are separated from each other by operating a facsimile machine 11. In FIG.

The operator calls the facsimile machine 2'1 by telephone, and after confirming that the facsimile ij[2 has been automatically activated and connected to the line, sets a remote diagnosis instruction to the facsimile machine 11. This instruction signal is transmitted from the man-machine interface section 11 in FIG. 1 to the control section 13. The facsimile machine 2 automatically starts up and sends a called station identification signal CED indicating that it has grabbed a line, and a non-standard equipment identification signal N8F indicating that it has the function to respond to the specified remote diagnosis. A digital identification signal indicating that it has a standard facsimile communication function is sent from the DISt control unit 23 through the modulation/demodulation unit 26.

The control section 13 of the facsimile machine 1 to which the remote diagnosis instruction has been set receives the non-standard identification signal N8F and the digital identification signal DI8'i through the modulation/demodulation section 16, and transmits the diagnosis to the factor iv device 2 later. data DATA
A non-standard scissors setting signal N881t, which instructs decoding and temporary storage, is generated and sent through the modem unit 16t. after that.

A training check signal TCP is sent to confirm whether the data can be transmitted without error at the speed at which the diagnostic data DATAlt is transmitted.

The facsimile machine 12 that received the non-standard device setting signal N881 and the training check signal TCrt sends a reception readiness confirmation signal CF as a default response to these signals.
The Rt-control unit 23 generates and sends it out.

Furthermore, the control unit 23 instructs the decoding unit 24 to decode diagnostic data DATAlt that is expected to be received thereafter and temporarily store it in the data storage unit 25.

The control section 13 of the facsimile apparatus 10 that received the reception preparation confirmation signal CFRvi instructs the encoding section 12 to encode the diagnostic data DATA1e stored in the data storage section 15 and transfer it to the modem section 16. The modulation/demodulation unit 16 sends encoded diagnostic data DATAlt-. This diagnostic data DATAI is sent to the facsimile Pi as described above.
- [Received by i12.

It is decoded by the decoding unit 24 and stored in the data storage unit 25.
A message end signal EOM is generated to indicate that the transmission of ATAI has been completed and to return to the beginning of the procedure.

Upon receiving the message end signal EOMt, the facsimile machine 2 sends a message confirmation signal M as a response.
CFt - Send.

Thereafter, the aforementioned non-standard device identification signal, N8F, and digital identification signal DIS are transmitted. In response, facsimile group #1 sends to facsimile group [2 a non-standard device command N8C1 indicating that the diagnostic data DATA lt- stored in data storage section 25 should be returned as is.

Facsimile machine 2 that received non-standard device command N8C1
The non-standard device setting signal N8S2 indicates that the data instructed by the non-standard device command N8C1 will be transmitted, and the training to confirm whether the data can be transmitted without error at the line speed at which the data is transmitted. Check signal TC

This data is directly transferred to the data storage section 15 through the modulation/demodulation section 16 and decoding section 14 of the facsimile machine 1. When the encoding unit 22 finishes transmitting the diagnostic result data DATA2t, the control unit 23 sends a procedure end signal EOP'i indicating that the transmission of the diagnostic result data DATA2 has been completed.
Occur.

Upon receiving the procedure end signal EOP, the facsimile IJ equipment 1 transmits a message confirmation signal MCF'i indicating that the reception of the diagnostic result data DATA2 has been completed.

Upon receiving the message confirmation signal MCF-i, the facsimile machine 2 transmits a disconnection command DCN, disconnects the line, and automatically stops.

Now, upon receiving the diagnostic result data DATA2, the control [13 of the nine-frame facsimile storage 1] compares the diagnostic data DATA1 initially sent to the facsimile machine 2 with the decoded data instructed by the non-standard device setting signal N881. The results are supplied to the man-machine interface section 11 and displayed.

As described above, the operator of the facsimile machine 1 can remotely diagnose the decoding function of the facsimile machine 2 which is separated from the facsimile machine 1 by using this display.

FIG. 2 shows a facsimile machine 1 for the above-mentioned remote diagnosis.
This figure shows a signal sequence that is shifted between 1 and 2.

Similarly, the facsimile machine 1 sends the diagnostic data DATAI in the data storage section 15 directly to facsimile 1! ! 6
