As illustrated in FIG. 3, the CPU 23 implements the functions of the acquisition unit 41, the analysis unit 42, and the display control unit 43 by executing a transmission error analysis program.

  The acquisition unit 41 acquires transmission error information indicating that a transmission error has occurred from the communication unit 24. The analysis unit 42 identifies the cause of the transmission error by referring to the error type determination information and the detailed error analysis information. The display control unit 43 displays information indicating the cause of the transmission error specified by the analysis unit 42 on the touch panel 21.

(Transmission error cause display operation)
FIG. 4 is a flowchart showing a flow of a display error cause display operation in the analysis unit 42 of the MFP 3. In step S1, the acquisition unit 41 acquires an error class and an error code for analyzing a transmission error from an SMB (Server Message Block) protocol that is a communication protocol, and notifies the analysis unit 42 of the error class. The analysis unit 42 determines whether or not a transmission error has occurred based on the error class and error code notified from the acquisition unit 41 (step S2). If the analysis unit 42 determines that a transmission error has not occurred (step S2: No), the entire processing of the flowchart of FIG.

  On the other hand, when it is determined that a transmission error has occurred (step S2: Yes), the analysis unit 42 is stored in the information storage unit 22 based on the error class and error code notified from the acquisition unit 41. The error type determination information is referred to, the type of transmission error is confirmed, and it is determined whether detailed analysis of the error is necessary (step S3). If it is determined from the type of transmission error that detailed analysis of the error is not necessary (step S3: No), the process proceeds to step S5. In step S5, the display control unit 43 displays text information (message or the like) indicating the cause of the transmission error determined based on the error class and the error code on the touch panel 21, and ends the process of the flowchart of FIG. To do.

  Table 1 below shows the storage contents of the error type determination information that the analysis unit 42 refers to when determining whether transmission error type confirmation and detailed analysis of an error are necessary.

  As can be seen from Table 1, as the error type determination information, information indicating the error type corresponding to the error class and the error code, and information indicating the necessity of detailed analysis of the transmission error are stored in association with each other. Yes. Specifically, when the error class is “0x01” and the error code is “ERRbadfunc”, the analysis unit 42 sets the error type to “transmission that occurs when the function is invalid and the parameter to the server is incorrect. It is determined as “error”. In this case, it is determined that detailed analysis of the error is “necessary”.

  Similarly, when the error class is “0x01” and the error code is “ERRbadpath”, the analysis unit 42 determines the error type as “transmission error that occurs when the specified directory cannot be found”. In this case, the detailed analysis of the error is determined as “No”.

  Similarly, when the error class is “0x02” and the error code is “ERRbadpw”, the analysis unit 42 determines the error type as “transmission error that occurs when the password is incorrect”. In this case, the detailed analysis of the error is determined as “No”.

  Similarly, when the error class is “0x03” and the error code is “ERRbadunit”, the analysis unit 42 sets the error type to “transmission error that occurs due to server side reasons such as server side resource shortage or server internal error. Is determined as follows. In this case, it is determined that detailed analysis of the error is “necessary”.

  When the display control unit 43 determines that the detailed analysis of the error is “No” (step S3: No), in step S5, for example, the error type is set to “transmission error that occurs when the password is incorrect”. The displayed text information or message is displayed on the touch panel 21.

  Next, in step S3 of the flowchart of FIG. 4, when it is determined that the detailed analysis of the transmission error is “necessary” and the process proceeds to step S4, the analysis unit 42 details the error stored in the information storage unit 22. Based on the analysis information, the transmission error is analyzed in detail. Tables 2 and 3 below show the storage contents of the detailed error analysis information.

  As can be seen from Tables 2 and 3, as the error detailed analysis information, each information of the error type, the detailed analysis type, and the display content of the transmission error is stored in association with each other. The detailed analysis type is information indicating detailed analysis contents of the transmission error. The analysis unit 42 analyzes the content indicated by this detailed analysis type. The display content of the transmission error is a message to be displayed as a result of analyzing the content indicated by the detailed analysis type.

  The error type is an error type for which detailed analysis of a transmission error is determined as “necessary” based on the error type determination information described above. Table 2 shows the detailed analysis type and the transmission error display contents for the error type “transmission error that occurs when the function is invalid and the parameter to the server is incorrect”. Table 3 is a table showing the detailed analysis type and the transmission error display contents for the error type “transmission error that occurs due to server-side reasons such as server-side resource shortage or server internal error”.

  When the analysis unit 42 determines that the detailed analysis of the transmission error is “necessary” based on the error type determination information, the analysis unit 42 refers to the error detailed analysis information shown in Tables 2 and 3 and performs the detailed analysis of the transmission error “necessary”. The detailed analysis type and the transmission error display content corresponding to the determined error type are detected. Then, the analysis unit 42 performs a detailed transmission error analysis indicated by the detailed analysis type, and notifies the display control unit 43 of the analysis result. The display control unit 43 displays a message or the like indicated by the transmission error display content on the touch panel 21 according to the notified analysis result.

  More specifically, the analysis unit 42 uses the error class and error code to determine the details of the transmission error according to the error type “transmission error that occurs when the function is invalid and the parameter to the server is incorrect”. When it is determined that the analysis is “necessary”, the error detailed analysis information shown in Table 2 is referred to. For this error type, as shown in Table 2, for example, “Are the same computer in the same network? The computer name in the network transmitted to the router is acquired. The detailed analysis contents of “confirm whether it exists” are shown.

  Therefore, the analysis unit 42 acquires the computer name in the network transmitted to the router 4 according to the detailed analysis type, and checks whether there is a computer similar to the transmitted computer name. Then, the analysis result is notified to the display control unit 43. If the display control unit 43 is notified of an analysis result indicating that a computer having the same name as the transmitted computer name (computer name of the information terminal 1) is present, in step S5 of the flowchart of FIG. A transmission error message such as “the same computer exists” is displayed on the touch panel 21.

  Similarly, the analysis unit 42 performs a detailed analysis of the transmission error according to the error class and the error code, according to the error type of “transmission error caused by the server side, such as a server side resource shortage or a server internal error”. If it is determined as “necessary”, the error detailed analysis information shown in Table 3 is referred to. For this error type, as shown in Table 3, for example, a detailed analysis content that “a request for obtaining a network bandwidth limit is made to a router whose transmission image is narrower than the network bandwidth limit and compared with transmission information” It is shown.

  For this reason, the analysis unit 42 requests the router 4 to acquire the limited bandwidth of the network 5 according to the detailed analysis type. Then, the analysis unit 42 compares the information on the bandwidth limit of the network 5 acquired from the router 4 with the image information of the transmission image, and determines whether or not the transmission bandwidth of the transmission image is narrower than the bandwidth limit of the network 5. Determine. The analysis unit 42 notifies the display control unit 43 of the determination result. When the display control unit 43 is notified of an analysis result indicating that the transmission band of the transmission image is wider than the limit band of the network 5, in step S5 of the flowchart of FIG. Or lower the resolution of the transmission image ”or the like is displayed on the touch panel 21.

  Similarly, the analysis unit 42 performs a detailed analysis of the transmission error according to the error class and the error code, according to the error type of “transmission error caused by the server side, such as a server side resource shortage or a server internal error”. If it is determined as “necessary”, the error detailed analysis information shown in Table 3 is referred to. For this error type, as shown in Table 3, for example, there is a detailed analysis content such as “request network traffic information from the router where the information terminal network is congested and compare with the transmission image”. It is shown.

  Therefore, the analysis unit 42 requests the router 4 to acquire the traffic information of the network 5 according to the detailed analysis type. Then, the analysis unit 42 compares the traffic information acquired from the router 4 with the image information of the transmission image, and determines whether or not the network 5 is congested from the network traffic with respect to the information amount of the transmission image. The analysis unit 42 notifies the display control unit 43 of the determination result. When the analysis result indicating that the network 5 is congested is notified, the display control unit 43, for example, in step S5 of the flowchart in FIG. 4, for example, “The network is congested. A transmission error message such as “.” Is displayed on the touch panel 21.

(Error detailed analysis operation)
FIG. 5 is a flowchart showing a detailed flow of the error detailed analysis operation in step S4 of the flowchart of FIG. If it is determined in step S3 of the flowchart of FIG. 4 that detailed error analysis is necessary from the error type, the process proceeds to step S11 of the flowchart of FIG. In step S11, the analysis unit 42 makes preparations for referring to the detailed error analysis information shown in Tables 2 and 3. That is, in step S12, the analysis unit 42 sets “line number” of the line of the detailed error analysis information to be referred to as “1”.

  The analysis unit 42 refers to Table 2 when the error type is an error type “transmission error that occurs when the function is invalid and the parameter to the server is incorrect”. The analysis unit 42 refers to Table 2 when the error type is an error type of “transmission error that occurs due to server-side reasons such as server-side resource shortage or server internal error”.

  The “line number” indicates the number assigned to the detailed error analysis information in Table 2 or Table 3 that the analysis unit 42 will refer to. In other words, “line number” indicates a number assigned to each “error type, detailed analysis type, and transmission error display content”. In the case of the example shown in Table 3, the error type is “transmission error that occurs due to server-side errors such as server-side resource shortage or server internal error”, “the transmission image is smaller than the network bandwidth limit, and the network is connected to the router. Request for acquisition of limited bandwidth and compare with transmission information "and transmission error display content of" Please widen the bandwidth limit of the network or lower the resolution of the transmission image. " Is assigned a line number of “1”.

  Similarly, in the case of the example shown in Table 3, the error type “transmission error that occurs due to server-side reasons such as server-side resource shortage or server internal error”, “the information terminal network is congested Request the network traffic information from the router and compare with the transmission image ”and the transmission error display content“ Network is congested. Please send after a while. ” On the other hand, the line number “2” is assigned.

  In step S12, the analysis unit 42 first sets a line number “1” to refer to the error detailed analysis information described first. And the analysis part 42 performs the above-mentioned error detailed analysis operation | movement in step S13. In addition, as a result of the detailed error analysis using Table 2 or Table 3 in step S14, the analysis unit 42 has caused a transmission error due to the items indicated by the detailed analysis types in Table 2 or Table 3. Determine whether or not.

  When the analysis unit 42 determines in step S14 that a transmission error has occurred due to the item indicated by the detailed analysis type in Table 2 or Table 3, the analysis unit 42 notifies the display control unit 43 of the analysis result. Accordingly, the process proceeds to step S5 of the flowchart of FIG. 4, and the display control unit 43 displays a message indicated by “transmission error display content” on the touch panel 21.

  On the other hand, if the analysis unit 42 determines in step S14 that the transmission error is not caused by the item indicated by the detailed analysis type in Table 2 or Table 3, the analysis unit 42 proceeds to step S15. In step S15, it is determined whether there is error detailed analysis information of the next line number. If the analysis unit 42 determines that the detailed error analysis information of the next line number does not exist (step S15: No), all the processes in the flowcharts of FIGS. 4 and 5 are terminated.

  On the other hand, for example, in the example of Table 3, the error detailed analysis information of the line number “2” is described after the error detailed analysis information of the line number “1”. For this reason, the analysis part 42 advances a process to step S16, when it determines with the error detailed analysis information of the following line number existing in step S15 (step S15: Yes). In step S16, the analysis unit 42 increments the line number by one (line number + 1), returns the process to step S13, and analyzes the error detailed analysis information of the line number “2”. In this way, the analysis unit 42 analyzes the detailed error analysis information while incrementing the line number one by one. The display control unit 43 displays an error message corresponding to the analysis result of the analysis unit 42 on the touch panel 21.

(Flow until the cause of the transmission error is displayed)
Next, FIG. 6 is a sequence diagram showing a flow of system operation from when a transmission error occurs from the MFP 3 to the user information terminal 1 until when a transmission error is displayed on the touch panel 21 of the MFP 3. In this case, the user operates the MFP 3 and instructs the shared folder of the information terminal 1 to transmit the image information read by the scan function or the like. When this instruction operation is performed, the MFP 3 transmits image information read by the scan function or the like in step S21. The image information transmitted from the MFP 3 is transmitted to the user information terminal 1 via the router 4.

  However, for example, when there are a plurality of terminal names of the information terminal 1 designated as the transmission destination by the user on the network 5 or when the network 5 to which the information terminal 1 is connected is congested, a transmission error occurs. To do. When a transmission error occurs, the router 4 notifies the MFP 3 of a transmission error as shown in step S22. The transmission error notification is acquired by the acquisition unit 41 of the MFP 3 and transferred to the analysis unit 42 in step S23.

  In step S24, the analysis unit 42 determines the necessity of the error type and detailed error analysis based on the error class and error code of the transmission error notification (see Table 1). If the analysis unit 42 determines that an error detailed analysis is required for the error type of the transmission error that has occurred, in step S25, the analysis unit 42 starts a detailed analysis of the transmission error based on the error detailed analysis information (Table 2 and Table 3).

  Specifically, in step S26, the analysis unit 42, for example, transmits a request for acquiring a computer name in the network 5, a request for acquiring a limited bandwidth of the network 5, or a request for acquiring traffic information of the network 5, etc. Requests to acquire information necessary for analyzing transmission errors. The router 4 returns the requested information to the MFP 3 in step S27. In step S28, the analysis unit 42 analyzes the cause of the transmission error in detail based on the information indicating the bandwidth limit of the network 5 acquired from the router 4 or the traffic information of the network 5.

  The analysis unit 42 repeats the processes in steps S26 to S28 until the cause of the transmission error is determined or until the analysis of the detailed error analysis information for all the “lines” described above is completed. Run.

  The analysis unit 42 notifies the display control unit 43 of such an analysis result. In step S29, the display control unit 43 displays an error message corresponding to the analysis result of the analysis unit 42 on the touch panel 21. Thereby, the detailed cause of the transmission error can be presented to the user.
