Description

Technical Field

[0001] The present disclosure relates to a technology for performing diagnosis on a network in an information processing device. Background Art

[0002] The present disclosure relates to an information processing apparatus that performs a task for transferring data to another personal computer (PC) or other information processing apparatuses.

[0003] Information processing devices that process image data and other information are of many types and varieties. These devices are prone to malfunction. When a malfunction occurs, repairs are necessary, but users often struggle to understand the cause. To address this issue, devices have been proposed that include diagnostic tools for identifying the cause of the malfunction and providing it to the user. The following description uses a multifunction peripheral as an example of an information processing device.

[0004] On the other hand, as discussed in Japanese Patent Application Laid-Open No. 2020-154832, the increasing complexity of security and functionality required for networks requires an environment in which multiple local area networks (LANs) can be selectively used. Information processing devices used in such environments need to provide services to multiple LANs. Therefore, a configuration has been proposed that connects multiple LANs to a single multifunction peripheral device.

[0005] As a diagnostic method, a method has been proposed for selecting a job to be executed by an information processing device and performing a diagnosis related to that job. If the selected job involves transferring data to another device, the line is diagnosed. Previously, a method has been proposed for diagnosing a configuration where a LAN is connected to a single information processing device.

[0006] Therefore, when diagnosing a configuration in which multiple LANs are connected to one information processing device, a LAN different from the LAN used for the selected job may be diagnosed. In this case, accurate diagnosis cannot be performed, and the user cannot identify the cause of the information processing device failure. Summary of the Invention

[0007] According to one aspect of the present disclosure, there is provided an information processing apparatus capable of being directly connected to each of a plurality of wired lines, the information processing apparatus comprising: an execution unit configured to execute a job using any one of the plurality of wired lines; a storage unit configured to store job information about one or more jobs executed by the information processing apparatus in a storage device of the information processing apparatus; a receiving unit configured to receive a selection of a record from records respectively related to corresponding jobs of the one or more jobs managed based on the job information stored in the storage device; and a diagnosis unit configured to diagnose the wired line used in the job corresponding to the selected record.

[0022] <System Configuration>

[0023] A first exemplary embodiment of the present disclosure will now be described. In this exemplary embodiment, a multifunction peripheral (MFP) including two communication lines (i.e., a main line (a first wired line) and a secondary line (a second wired line)) is used as an example to describe network diagnostic processing. A configuration in which multiple wired lines are connected is described as an example. However, the technology is also applicable to a virtual separated communication line using a virtual network interface. The information processing device is not limited to an MFP, and may also be an information processing device that provides other functions.

[0024] Figure 1 : is a diagram illustrating a connection form of an MFP, a gateway, and a client terminal such as a personal computer (PC) according to the present exemplary embodiment.

[0025] The MFP 100 includes a controller unit 101, an operating unit 102, a printer unit 103, and a scanner unit 104. The configuration of the controller unit 101 will be described in detail below. The operating unit 102 is an interface for input and output with a user. The printer unit 103 includes a printing unit capable of outputting electronic data to a paper medium. The scanner unit 104 includes a reading unit capable of reading an image and converting the read image into electronic data. The operating unit 102, the printer unit 103, and the scanner unit 104 are connected to the controller unit 101 and, under the control of the controller unit 101, implement the functions of a multifunction peripheral. The units included in the MFP 100 are not limited to these units, and may include units that provide other functions.

[0026] The MFP 100 and the client terminal 112 are communicatively connected to each other via a local area network (LAN) 110 and a gateway 111. Devices other than the MFP 100, such as the client terminal 112 and the client terminal 122, are referred to as other devices. The MFP 100 and the client terminal 122 are communicatively connected to each other via the LAN 120 and the gateway 121. The gateways 111 and 121 are network routers that relay communications from the MFP 100 to the client terminal 112 and the client terminal 122. Each of the client terminals 112 and 122 shares files with the MFP 100 and transmits print requests to the MFP 100 using, for example, the Server Message Block (SMB) protocol.

[0027] Now refer to Figure 2 The hardware configuration of the MFP 100 according to the present exemplary embodiment is described.

[0028] Figure 2 1 is a block diagram illustrating the hardware configuration of MFP 100. MFP 100 includes a reading function for reading an image on a sheet, a file transfer function for transferring the read image to an external communication device, and other functions. MFP 100 also includes a printing function for printing an image on a sheet. MFP 100 includes the function of receiving a print job from client terminal 112 and printing the print job.

[0029] A central processing unit (CPU) 201 controls the overall operation of the MFP 100. The CPU 201 reads out a control program stored in a read-only memory (ROM) 202 or a storage device 204, and performs various types of control such as print control and read control.

[0030] The ROM 202 stores control programs to be executed by the CPU 201 .

[0031] A random access memory (RAM) 203 is a main memory accessed by the CPU 201 , and the RAM 203 is used as a work area or a temporary storage area for loading various types of control programs.

[0032] The storage device 204 stores print jobs, image data, various types of programs, and various types of setting information. Thus, hardware devices such as the CPU 201, ROM 202, RAM 203, and storage device 204 configure a computer. In the MFP 100 according to this exemplary embodiment, a single CPU 201 performs the process shown in the flowchart described below using a single memory (RAM 203), but other forms may be adopted. For example, multiple processors, memories, and storage devices may cooperate with each other to perform the process shown in the flowchart described below. These processes may be partially performed by hardware circuits.

[0033] The CPU 201 is connected to the Figure 1 The CPU 201 is connected to the printer via the printer I / F 207. Figure 1 The printer unit 103 shown in FIG. 1 is used, and the CPU 201 implements sheet medium output processing (print processing) using the printer unit 103. The CPU 201 is connected to the scanner via the scanner I / F 206. Figure 1 The scanner unit 104 shown in FIG. 1 is used, and the CPU 201 implements document reading processing (scanning processing) using the scanner unit 104 .

[0034] Wired LAN devices 209 and 210 are connected to network I / F 208. In this exemplary embodiment, a configuration in which two wired LAN devices 209 and 210 are connected to network I / F 208 is described. However, this configuration is not limited thereto, and this exemplary embodiment is applicable to other LAN devices, such as wireless LAN devices and LAN devices connected to a universal serial bus (USB) port, as well as other connection configurations. CPU 201 controls wired LAN device 209 via network I / F 208 to enable communication on LAN 110. CPU 201 controls wired LAN device 210 to enable communication on LAN 120.

[0035] <Software Configuration>

[0036] Figure 3 is a block diagram illustrating the software configuration of the MFP 100 according to the present exemplary embodiment.

[0037] The screen operation control unit 301 controls to display a screen for issuing a scan operation instruction via the operation unit 102 , and displays print results, transmission of scan data, and processing results performed by a network diagnostic unit, which will be described below.

[0038] The setting management unit 302 manages settings of various types of functions of the MFP 100 .

[0039] The various types of setting values ​​include, for example, setting values ​​for scanning, sheets of print processing, image processing, and communication with a communication terminal. These setting values ​​are stored in a nonvolatile area such as the storage device 204 and are stored regardless of the power state of the MFP 100.

[0040] The setting management unit 302 performs control to retrieve a setting value from the nonvolatile area, and the setting management unit 302 performs control to change the setting value to a different setting value and store the result.

[0041] The scanner control unit 303 issues an instruction to transmit predetermined data obtained by the MFP 100 through scanning using the scanner unit 104 to other devices such as the client terminals 112 and 122 .

[0042] The scanner control unit 303 acquires setting values ​​for the scan process and the scan data transmission process via the setting management unit 302 , and the scanner control unit 303 issues an instruction to transmit the scan data to the target terminal via the communication control unit 307 .

[0043] The print control unit 304 receives a print job received by the MFP 100 from another device, and causes the printer unit 103 to perform a series of print processes up to sheet discharge processing via the printer I / F 207. The print control unit 304 acquires setting values ​​for print processing via the setting management unit 302, analyzes the received print job, performs image processing, and performs print processing and sheet discharge processing.

[0044] The job log management unit 305 manages information on the results of print processing and scan processing.

[0045] The job processing result information includes information indicating whether the processing is successful or failed. In the case of failure, the result information may include the network diagnosis result received from the network diagnosis unit 306.

[0046] The job processing result information is stored in a nonvolatile area such as the storage device 204 or a job log management server on the network, and is stored regardless of the power status of the MFP 100 .

[0047] The job log management unit 305 receives the results of the processes performed by the scanner control unit 303 and the print control unit 304 , and the job log management unit 305 stores the results in a nonvolatile area or a job log management server.

[0048] In addition, the job log management unit 305 retrieves the job processing result information from the nonvolatile area, and transfers the job processing result information to the screen operation control unit 301. The screen operation control unit 301 displays the job processing result information on the operation unit 102.

[0049] exist Figure 1 In the configuration shown in , the network diagnostic unit 306 performs validity verification on the network communication settings stored by the MFP 100 .

[0050] Validity verification involves, for example, verifying that the settings of the Internet Protocol (IP) address, subnet mask, and gateway 111 used for network communication with the LAN 110 are correct. In addition, the network diagnostic unit 306 verifies that the client terminal 112 and the MFP 100 do not use the same IP address.

[0051] The network diagnostic unit 306 regularly diagnoses the status of the physical communication links to the connected LANs 110 and 120. Regular diagnosis is performed in response to instructions from the screen operation control unit 301, the scanner control unit 303, and the print control unit 304. Furthermore, if the network diagnostic unit 306 detects that a communication link has been disconnected, the network diagnostic unit 306 notifies the screen operation control unit 301, the scanner control unit 303, and the print control unit 304 of the disconnection.

[0052] The network diagnostic unit 306 includes a diagnostic unit for diagnosing the information processing device. The diagnostic unit can check the status of the information processing device. For example, if communication with client terminals 112 and / or 122, acting as communication partners, fails during the transmission of scanned data or during the printing process, the diagnostic unit can diagnose the cause of the failure. The diagnostic unit for identifying the cause of the failure includes performing a connection check with client terminals 112 and 122 and performing test communication.

[0053] The communication control unit 307 performs network communication control to transmit the scanned data to the client terminals 112 and 122 in response to a transmission instruction from the scanner control unit 303 .

[0054] For a configuration including the wired LAN devices 209 and 210 as shown in the present exemplary embodiment, the MFP 100 can store two types of media access control (MAC) addresses and IP addresses as a multi-homed network environment, thereby enabling communication via both the LANs 110 and 120. The communication control unit 307 performs communication control by identifying a partner terminal in the multi-homed network environment and establishing a network connection.

[0055] <Screen Configuration>

[0056] The error guide will now be described.

[0057] Figures 4 to 6 Examples of error guidance, etc. are shown in the figure.

[0058] Figure 44 is a diagram illustrating an example of a print job history list managed in the storage device 204 by the print control unit 304 and displayed on the operation unit 102 of the MFP 100. In the print job list 400 in which the history of print jobs executed by the MFP 100 is displayed as a list, a date and time 401, a department identification (ID) 402, a user name 403, a job name 404, and a result 405 are managed in association with one another.

[0059] The date and time 401 shows the date and time when the job was executed. The department ID 402 shows the ID of the department to which the user corresponding to the user name 403 who has executed the job belongs.

[0060] The user name 403 displays the name of the user who has executed the job, and the job name 404 displays the name of the executed job.

[0061] The result 405 displays the execution result of the job.

[0062] In the print job list 400, the values ​​of the data fields 401 to 405 are as respective items (respective history records). As described above, each item includes information about a single job. The user can select the item. The MFP 100 can receive the user's selection through the operation unit 102 included in the MFP 100. When the user selects the item through the operation unit 102, the user can select the item. Figure 4 When the item 406 on the display is selected and the operation unit 102 further receives selection of the diagnosis button 407, the diagnosis starts.

[0063] Figure 5 3 is a diagram illustrating an example of a diagnosis result displayed by the display unit. The diagnosis result is displayed by the display unit on the operation unit 102 of the MFP 100. The diagnosis result is a result of the network diagnosis unit 306 diagnosing the item received by the operation unit 102.

[0064] When the user operates the operation unit 102 and presses the diagnosis button 407, the diagnosis result 500 is displayed, and the network diagnosis performed in response to the user operation is completed. The failure cause description message 501 displays a message describing the reason why the job failed. The solution description message 502 displays the solution corresponding to the failure cause displayed in the failure cause description message 501. In the case where the solution to the failure cause is described in a user manual that can be browsed on the web, a two-dimensional code 503 indicating the uniform resource locator (URL) of the user manual is displayed. When the return button 504 is pressed, the display returns to the print job list 400 where the diagnosis button 407 was pressed.

[0065] In the present exemplary embodiment, description is made by taking a print job as an example; however, a history list of a scan job or the like can be similarly displayed. The associated data fields are not limited to the fields described in the example.

[0066] <Processing Flow>

[0067] Now refer to Figure 6 A network diagnosis process using a job history according to the present exemplary embodiment is described.

[0068] In step S601, the operation unit 102 of the MFP 100 receives selection of an item and selection of the diagnosis button 407. The user presses the corresponding button. Then, network diagnosis is started.

[0069] In step S602, the network diagnostic unit 306 included in the MFP 100 determines the line setting. More specifically, the network diagnostic unit 306 determines whether the network includes a dual network (i.e., two LAN systems). In the present exemplary embodiment, the network diagnostic unit 306 determines whether the line setting allows the simultaneous use of the main line (first wired line) and the secondary line (second wired line) (such a setting is referred to as the first setting), or whether the line setting allows only the main line to be used (such a setting is referred to as the second setting). If the determination result is the first setting ("Yes" in step S602), the process proceeds to step S603. If the determination result is the second setting ("No" in step S602), the process proceeds to step S606.

[0070] In step S603 , the network diagnosis unit 306 first performs network diagnosis on the main line.

[0071] In step S604 , the network diagnosis unit 306 performs network diagnosis on the secondary line.

[0072] In step S605, the display is as follows Figure 7 Diagnostic results shown in . Figure 7 The configuration shown in Figure 5 The configuration is similar to that shown in .

[0073] In step S606, the network diagnostic unit 306 performs network diagnostics on the primary line. For the second setting, the primary line is used, so there is no need to diagnose the secondary line. Therefore, the secondary line is not diagnosed. This allows diagnosis without unnecessary diagnostic processing. The results of the network diagnostics in step S606 are then displayed on the operating unit 102, and the sequence is complete.

[0074] Figure 7 is a diagram illustrating an example of a diagnosis result 700 in a case where the diagnosis of the main line and the diagnosis of the sub-line are performed in a state where the MFP 100 is set to the first setting. Figure 7 The contents 701-704 shown in FIG. Figure 5501-504 in the first setting. In the case of the first setting, the display unit displays the diagnosis results for both the main line and the sub-line, regardless of the line used to perform the job. For example, if a job using the main line is diagnosed and the cause of an error is found in the main line but no error occurs in the sub-line, the user can realize that the user can reconfigure the settings to use the sub-line for the job.

[0075] Figure 8 It is a graph that also illustrates the diagnosis result through the display unit. Figure 8 The display contents 801-804 in the corresponding Figure 7 701-704. Figure 8 As shown in message 801 in FIG, the diagnosis result may indicate that the status is normal. This enables accurate notification of the network status to the user.

[0076] In this exemplary embodiment, the MFP includes two communication lines: a main line and a sub-line. However, the sub-line can be installed as needed. In an MFP without a sub-line installed, network diagnostics for the sub-line are not performed. The user can optionally set whether to use the sub-line even with the optional sub-line installed.

[0077] When the secondary line is available, the user sets up the secondary line. In this exemplary embodiment, a network interface 208 for transmitting data to other devices is included, and the secondary line is used to transmit data to a predetermined IP address. The user registers the predetermined IP address in advance. The predetermined IP address and the secondary line are registered in association with each other, so that data can be transmitted to and received from the predetermined IP address using the secondary line.

[0078] In the case of transmitting data to (or receiving data from) an IP address that is not registered as an IP address using the secondary line, the primary line is used.

[0079] As described above, the present exemplary embodiment provides the user with the cause of a failure or error by diagnosing the wired lines in a configuration where multiple wired lines are available. In the first exemplary embodiment, the line to be diagnosed is selected based on whether the setting is the first setting or the second setting, so that diagnosis can be performed without diagnosing unused lines.

[0080] A second exemplary embodiment will now be described. In this exemplary embodiment, a diagnosis for a mode in which a job and line information are associated with each other is described. Descriptions of the same parts as in the first exemplary embodiment are omitted.

[0081] Apart from Figure 4 In addition to the data fields shown in Figure 9Also shown is information indicating which network (LAN 110 or LAN 120) the print job was received from, such as a data field "Line" 908. Thus, diagnosis of the corresponding line can be performed. In print job list 900, data fields 901 to 905 and a diagnostic button 907 correspond to data fields 401 to 405 and diagnostic button 407, respectively.

[0082] <Processing>

[0083] Now refer to Figure 10 The network diagnosis processing based on the job history according to the present exemplary embodiment is described. Figure 9 When the item 906 in is selected and the operation unit 102 further receives selection of the diagnosis button 907 in step S1001, the diagnosis starts.

[0084] In step S1002, Figure 9 Information about the line corresponding to the job is acquired from the data field "Line" 908 shown in FIG. If the line information indicates a main line ("Main Line" in step S1002), the process proceeds to step S1003. If the line information indicates a sub-line ("Sub-line" in step S1002), the process proceeds to step S1004.

[0085] In step S1003 , the network diagnosis unit 306 performs network diagnosis on the main line.

[0086] The process advances to step S1005 , and the diagnosis result is displayed.

[0087] In step S1004 , the network diagnosis unit 306 performs network diagnosis on the secondary line.

[0088] The processing then proceeds to step S1005.

[0089] As described above, according to this exemplary embodiment, the line to be diagnosed is selected based on the line used for the operation of the selected item. This can narrow the range of the diagnosis lines and thus reduce the diagnosis time.

[0090] A third exemplary embodiment will now be described. In this exemplary embodiment, instead of displaying the diagnosis results for both the main line and the sub-line, a process will be described in which the user determines the line to be diagnosed.

[0091] Figure 11 It is a graph that also illustrates the diagnosis result through the display unit. Figure 11 The display contents 1101-1104 in the corresponding Figure 7 701-704. Figure 11 In addition to Figure 7In addition to the information shown in , the secondary line diagnosis button 1105 is also included. In response to detecting that the button is being pressed, the secondary line diagnosis is performed.

[0092] Now refer to Figure 12 The following describes network diagnostic processing using job histories according to this exemplary embodiment. In step S1201, when an item is selected from the print job list 900 and the diagnostic button 907 is selected, diagnosis of the job history corresponding to the selected item begins. In step S1202, the main line is diagnosed regardless of the line used for the job of the selected item.

[0093] In step S1203 , only the diagnosis result of the main line among the main line and the sub-line is displayed.

[0094] In step S1204, if the user presses secondary line diagnosis button 1105 (YES in step S1204), the process proceeds to step S1205. If secondary line diagnosis button 1105 is not pressed (NO in step S1204), the diagnosis ends.

[0095] In step S1205 , the network diagnosis unit 306 performs network diagnosis on the secondary line.

[0096] In step S1206 , the result of the diagnosis of only the secondary line among the main line and the secondary line is displayed.

[0097] like Figure 13 As shown in , a setting unit that determines whether to perform diagnosis on each of the main line and the sub-line may be provided.

[0098] This causes the diagnostic to be performed only when the setting value is On. Figure 13 In the case of , when performing diagnosis, only the main line is diagnosed. In addition, if there is no secondary line configuration, the settings for the secondary line can be omitted.

[0099] As described above, according to the present exemplary embodiment, it is possible to notify only the diagnostic information desired by the user.
