Description

The present invention relates to an image forming apparatus , a control method thereof , and a program.

  When performing maintenance of the image forming apparatus, a service manual for each model is required. In the case of a large-sized image forming apparatus, a large number of optional devices are connected and there are various types, so that a large amount of service manuals are required. Bookbinding manuals are not portable and are not realistic to carry. Therefore, recent service manuals have been digitized and can be viewed on a personal computer (PC) or the like. However, there are cases where a serviceman is not allowed to bring a PC to a customer due to security issues.

  It is also possible to prepare an electronic manual on an external Web server and refer to it via a Web browser. However, depending on the customer's network environment and security settings, the external Web server may not be accessible. For this reason, digitized manuals are prepared in the image forming apparatus, and can be referred to by a Web browser installed on a customer's PC or an external controller using the Web server function of the image forming apparatus. Conceivable. Further, Patent Document 1 proposes a technique for providing a web server function to an externally manufactured controller and operating using the web server function in the case of a large model to which an externally manufactured controller is connected such as a POD machine.

For example, there are cases where manual content data cannot be installed due to security problems of an externally manufactured controller, problems with hardware specifications, or the convenience of the externally manufactured controller. Further, when there are a plurality of externally manufactured controllers, it is necessary to prepare manual contents that match the specifications of the Web server function in which each externally manufactured controller is mounted. Furthermore, in the first place, there is a problem that it is not possible to cope with a non-large model to which an external controller is not connected. Therefore, it is assumed that the Web server function provided in the image forming apparatus itself is used.

  However, some of the maintenance operations for the image forming apparatus require that the power be turned off, and the post-processing is performed when the image forming apparatus is turned on again after completion of the work performed while the image forming apparatus is turned off. May be necessary. For example, it is necessary to perform an initialization process for a work target component. If a part is replaced, it is necessary to initialize a counter that measures the degree of wear of the corresponding part or to readjust the operation that is affected by the work. If post-processing is not carried out, the life of parts cannot be managed correctly, and image quality problems may occur. Therefore, even when the Web function is used, the maintenance worker needs to remember what work was performed while the power of the image forming apparatus was turned off, and further post-processing corresponding to the work. Must be carried out without omission, and this is a burden on the operator.

  The present invention has been made in view of the above problems, and when a maintenance work or the like is performed by turning off the power, at the time of restarting, while grasping the work performed while the power is turned off, It is an object of the present invention to provide a mechanism for suitably executing post-processing of the work.

The present invention provides an image forming apparatus having a Web server, which provides storage means for storing manual data and page data for displaying a screen for instructing shutdown of the image forming apparatus on a Web browser provided in an external terminal.

The MFP 101 includes a controller unit 200 to which a scanner 213 and a printer 214 are connected, and an operation display unit 211, an operation input unit 212, and a LAN 102 can be connected. The controller unit 200 includes a CPU 201, a RAM 202, a ROM 203, an HDD 204, an operation unit output I / F 205, an operation unit input I / F 206, a network I / F 207, a scanner I / F 208, and a printer I / F 209. A CPU (Central Processing Unit) 201 executes various control programs. The CPU 201 activates the system based on a boot program stored in a ROM (Read Only Memory) 203. Then, a control program stored in the HDD (Hard Disk Drive) 204 is read on this system, and predetermined processing is executed using the RAM (Random Access Memory) 202 as a work area. Various control programs are stored in the HDD 204. The HDD 204 stores scan data read from the scanner 213 and data acquired from outside the apparatus via the network I / F 207.

  The operation unit output I / F 205 performs data output communication control to the operation display unit 211. The operation unit input I / F 206 performs data input communication control from the operation input unit 212. A network I / F 207 is connected to the LAN 102 and performs input / output control of information via the LAN 102. A scanner I / F 208 inputs image data from the scanner 213 and inputs / outputs scanner control data. A printer I / F 209 outputs output image data to the printer 214 and inputs / outputs printer control data. Each component 201 to 209 is disposed on the system bus 210.

  The operation input unit 212 is an instruction input interface from a user (operator) provided with an input device such as a touch panel and hard keys. The operation display unit 211 is a display interface for a user including a display device such as an LCD (Liquid Crystal Display) and an LED (Light Emitting Diode). The scanner 213 includes an optical reading device such as a CCD (Charge Coupled Device), and has a function of optically operating a paper medium to read it as electronic image data. The printer 214 has a function of forming electronic image data as an image on a recording medium such as paper.

  Next, the control configuration of the MFP 101 will be described with reference to FIG. 3 is realized by the CPU 201 in the MFP 101 reading and executing a control program stored in the ROM 203 or the HDD 204. Here, since the external server 104 can have the same software configuration, the description of the external server 104 is omitted.

  The MFP 101 includes a Web server 301 and the network I / F 207 described above. The network I / F 207 performs communication in order to provide a Web service to the external terminal 105. In addition, communication with the external terminal 105 is performed in order to provide the screen operation on the operation panel of the MFP 101 to the VNC.

  Here, the external terminal 105 has a web browser 150 in order to receive provision of a web service. Further, in order to receive provision of a screen operation service on the operation panel of the MFP 101, a VNC 151 is provided. VNC is VIRTUAL NETWORK COMPUTING, which is remote desktop software that uses the RFB protocol for remotely operating a remote computer on a network.

  Specifically, the web server 301 transmits a request message to the web server 301 that provides a web service, receives a response message transmitted from the web server 301, and displays a screen on the web browser 150. The web browser 150 of the external terminal 105 can display manuals stored in the MFP 101 having the web server 301 by using the web services of these applications. In addition, the MFP 101 having the Web server 301 can be operated. Further, the VNC 151 requests a screen to be displayed on the operation panel of the MFP 101 via the input / output control unit 320, or receives a screen to be displayed on the operation panel transmitted from the MFP 101. The screen to be displayed above can be displayed.

  Next, the configuration of the Web server 301 will be described. The web server 301 includes a web service processing unit 310, an HTML screen generation unit 311, and a CGI processing unit 312. The Web service processing unit 310 has a function as an HTTP service that receives a request message from the Web browser 150 as a client and determines which Web application service is to be communicated according to the request message. Specifically, the URL and parameters are received as a request message, the received URL and parameters are analyzed, and the request is specified. Then, the process is executed in accordance with the identified request, and the response is returned to the Web browser 150 as the client.

  The CGI processing unit 312 is called from the web service processing unit 310 described above and receives a request message from the web service processing unit 310. Thereafter, in order to provide a Web service, a screen generation instruction process, which will be described later, is performed based on the request message described above. Specifically, the tag name in the HTML included in the parameter of the request message requested from the Web browser 150 is analyzed. When a tag name exists in the parameter, the screen generation instruction unit 313 is requested to perform screen generation instruction processing according to the contents of the tag name.

For example, it is assumed that the following tag is set in the menu “AAA” on the HTML.
<Div id = “TAG-MENU-01”> AAA </ div>
In this case, when the menu “AAA” is selected on HTML such as a manual displayed on the Web browser 150, id = “TAG-MENU-01” is transmitted as a parameter. Upon receiving “TAG-MENU-01” as the tag name, the CGI processing unit 312 calls the screen generation instruction unit 313 using the tag name as an argument, and performs screen generation instruction processing according to the contents of the tag name.

  The HTML screen generation unit 311 is called from the Web service processing unit 310 described above, and generates an HTML screen instructed from the Web browser 150. Specifically, when there is a manual display request from the Web browser 150, the HTML source of the corresponding manual data portion is read from the manual data 314, the corresponding screen is formed, and transmitted to the Web browser 150. Here, the manual data 314 is stored in advance in the aforementioned RAM 202 or HDD 204 area.

  In response to the request from the CGI processing unit 312, the screen generation instruction unit 313 performs information construction for generating an operation screen to be displayed on the VNC 151. Specifically, the item name to be displayed on the operation screen is specified from the tag name notified from the CGI processing unit 312. Then, the screen ID and button ID of the operation screen in which the item name exists are specified, and information necessary for display is set. The information is notified to the screen generation unit 321 and an operation screen generation instruction is issued.

  The input / output control unit 320 transmits the generated operation screen to the operation panel of the MFP 101 or the VNC 151 and receives an operation instruction on the operation screen. Specifically, a screen to be displayed on the operation panel of the MFP 101 is displayed on the operation display unit 211 via the operation unit output I / F 205. At the same time, if there is a connection request for the VNC 151, it is displayed on the VNC 151 via the network I / F 207. In addition, a user operation instruction in the operation input unit 212 is received via the operation unit input I / F 206. Furthermore, the user's operation instruction in the VNC 151 is received via the network I / F 207.

  The screen generation unit 321 receives a request from the input / output control unit 320 or the screen generation instruction unit 313 and generates a screen to be displayed on the operation panel. Specifically, the screen generation unit 321 reads a screen corresponding to the requested screen ID from the screen resource, arranges buttons and the like, generates a screen, and transmits the screen to the screen output unit 322. Alternatively, the screen generation unit 321 specifies the button ID of the corresponding item from the requested screen ID and the item name, generates a new screen, and transmits it to the screen output unit 322. The screen resource is preferably stored in advance in the memory area of the RAM 202 or the HDD 204. The screen output unit 322 transmits the screen to be displayed on the operation panel generated by the screen generation unit 321 to the input / output control unit 320.

<Operation Manual>
Next, an example of a manual displayed on the Web browser 150 in the present embodiment will be described with reference to FIG. The part replacement manual displays a replacement procedure for removing a part to be replaced from the MFP 101 and attaching a part to be replaced, and an adjustment process after the part replacement. The adjustment processing includes, for example, initialization processing of the component itself, processing for the MFP 101 to recognize the component, and post-processing such as readjustment of the operation of the MFP 101 related to the component.

  Reference numeral 401 denotes content displayed on the Web browser 150. FIG. 4 shows an example of the replacement procedure of a part called “ITB unit”. Reference numeral 402 denotes a “part replacement method”, and a specific operation procedure is described using an illustration as indicated by 403. The display area is scrollable, and detailed procedures can be displayed. In 404, an explanation of the adjustment procedure after component replacement is displayed. Here, an initialization process of the replaced part to be executed after the part replacement and a post-processing procedure necessary for correcting or readjusting the behavior of the device due to the replacement are displayed.

<Screen display processing>
Next, referring to FIG. 5 and FIG. 6, when the manual data 314 in the MFP 101 is displayed on the Web browser 150 on the external terminal 105, it is displayed on the Web browser 150 when the power of the MFP 101 is turned off. Screen transition and processing sequence will be described. The Web server 301 of the MFP 101 receives a manual display request from the Web browser 150 on the external terminal 105 and returns manual top screen data. As a result, the manual top screen 501 is displayed on the web browser 150. Further, the Web server 301 of the MFP 101 transmits data of a designated screen in accordance with a screen transition request issued when a plurality of menus prepared on the manual top screen are selected by a user operation. As a result, the screen after the transition is displayed on the web browser 150 on the external terminal 105.

  In step S <b> 601, when the Web server 301 receives a screen transition instruction to the component replacement screen 503 on the manual top screen 501 by a user operation, the Web server 301 returns the component replacement screen 503 to the Web browser 150. Here, the component replacement screen 503 includes maintenance component items 505, 0506, and 507 and check boxes for selecting those items. Further, the part replacement screen 503 includes a cache execution button 504 for acquiring manual data 314 for replacing the selected part from the MFP 101 as offline content. That is, the component replacement screen 503 is a selection screen that allows selection of any of a plurality of components that can be replaced in the MFP 101.

  When a maintenance component is selected on the component replacement screen 503 and the cache execution button 504 is operated, in step S602, the Web browser 150 receives selection information on the selected maintenance component, and transmits it to the Web server 301 in step S603. In step S604, the Web server 301 derives the manual content from the manual data 314 according to the selection information, and creates a cache instruction file using the file including the data. In step S <b> 605, the Web server 301 generates an offline menu screen (offline screen) 511 for displaying manual content corresponding to the selected maintenance component. Here, the offline menu screen 511 is a screen that displays only items that can be operated in the offline state, as shown in FIG. 8, and a manual related to the component selected on the component replacement screen 503 is displayed. It is a menu screen for displaying offline. Details will be described later.

Next, in S606, the Web server 301 transfers and stores the target content data to the content cache area, and the screen transitions to the shutdown execution screen 508. At this time, the HTML file (shutdown.html) on the shutdown execution screen 508 includes the following description as shown at 702 in FIG.
<Html manifest = “manifest. Appcache”>
In the above description, the cache instruction file “manifest.appcache” created in 604 is included. The contents of the cache instruction file are shown at 701 in FIG. The Web browser 150 that supports the application cache function of HTML5 reads the cache instruction file (extension appcache). Further, the web browser 150 reads the file described in the cache instruction file from the web server 301 into its own local cache. Thereafter, the web browser 150 accesses the file stored in the local cache without accessing the web server 301 and operates even if it is not connected to the web server 301.

  When the shutdown button 509 is operated from the shutdown execution screen 508, the Web browser 150 requests the Web server 301 to execute shutdown in S607, and monitors the connection state with the Web server 301 in S609. In step S <b> 608, when the web server 301 receives a shutdown execution request from the web browser 150, the web server 301 executes shutdown of the MFP 101.

  When the MFP 101 is shut down, the Web server 301 is also stopped. In the monitoring of the connection state with the Web server 301 in S609, if it is detected that the connection is lost (offline), the Web browser 150 stores the offline menu stored as the application cache in S610. A screen 511 is displayed. Further, in S611, the Web browser 150 functions as an operation recording unit, and records an operation when offline.

  Here, the offline menu screen will be described with reference to FIG. On the offline menu screen 801, only items selected as a cache countermeasure on the parts replacement screen 503 are displayed as menus. The example of FIG. 8 is an offline menu screen when “Drum replacement”, “ITB unit replacement”, and “Scanner unit” are selected on the parts replacement screen 503. In 802, 804, and 806, respective item names are displayed. On the right side of each item name 802, 804, 806, check boxes 803, 805, 807 that can be checked when the exchange operation is performed are arranged. These check boxes 803, 805, and 807 are selection items for leaving an operation history (operation information) performed on the MFP 101 when the MFP 101 is offline (shut down).

  When an item name 802, 804, or 806 is selected, a transition is made to a manual screen 512 for the operation of the item. The user who performs the part replacement performs the part replacement while confirming the operation procedure. When the replacement work is completed, the user adds a check mark to the check box arranged on the right side of the part. That is, the manual screen 512 that is an offline screen is a screen that displays a manual for replacing the part. In the example of FIG. 8, the check mark of the check box 805 corresponding to “ITB unit replacement” 804 is displayed, which means that it has been executed.

  Returning to FIG. 5 and FIG. In step S613, the Web browser 150 that is displaying the offline menu screen monitors whether it is online. The user who has performed the component replacement turns on the MFP 101 again when the component replacement operation is completed. Then, in step S612, along with the restart of the MFP 101, the Web server 301 in the MFP 101 is also restarted and starts operating. When the web browser 150 detects that the online state has been entered, the process advances to step S614 to notify the web server 301 of the operation information that has been checked while offline.

  Here, with reference to FIG. 9, the data structure at the time of notification will be described. The data is expressed by a combination of “KEY” − “VALUE”. In the example of FIG. 9, {“DRUM_UNIT” = “OFF”}, {“SCANNER UNIT” = “OFF”}, and {“ITB_UNIT” = “ON”}. The web browser 150 transmits array data including these three elements to the web server 301.

  Returning to FIG. 5 and FIG. Next, in step S615, when the Web server 301 receives the operation information, the Web server 301 transitions to a post-processing execution screen 513, and then starts processing the operation information. Details of the processing of the operation information will be described later with reference to FIG. In S616, when the post-processing is completed, the Web server 301 notifies the Web browser 150 of the completion of the post-processing. The web browser 150 that has received the notification transitions to the manual top screen 501.

<Process after return>
Next, a procedure of processing executed when the Web server 301 receives operation information from the Web browser 150 when returning to the online state will be described with reference to FIG. As described above in the description of FIG. 4, after each component replacement process, adjustment after component replacement is necessary. The MFP 101 manages post-processing after part replacement for each part replacement. FIG. 11 is an example of a table that defines post-processing when each component is replaced. For example, the replacement of the drum unit becomes “DRUM_UNIT” as the “KEY” value, indicating that two post-processing 1102 and 1103 are necessary. The processing described below is realized by the CPU 201 reading out and executing a control program stored in the ROM 203, the HDD 204, etc. into the RAM 202.

  In step S1002, the CPU 201 converts the received data as array data including elements of the data structure of KEY-VALUE. It is assumed that the “KEY” value at this time is the value described above. The processing from S1003 to S1007 is executed for each element of the obtained array data.

  Specifically, in S1004, the CPU 201 confirms the VALUE value of each element. If “NO”, the CPU 201 determines that the work corresponding to the KEY value has not been executed, and performs post-processing corresponding to the work. Since there is no need to execute, the process proceeds to the next element. On the other hand, if the VALUE value is “YES”, it is determined that the work corresponding to the KEY value has been executed, and the process proceeds to S1005, where the CPU 201 acquires post-processing corresponding to the KEY value from the management table, and in S1006 Perform post-processing. When execution of post-processing is completed for all the array elements, the processing is terminated.

  As described above, the image forming apparatus according to the present embodiment transmits screen information including at least a part of manual data that can be used during shutdown to the external terminal before shutting down. Further, after the restart, the image forming apparatus receives operation information indicating an operation performed on the image forming apparatus performed during the shutdown from the external terminal, and performs post-processing corresponding to the operation information. Execute. Thereby, according to the present embodiment, when maintenance work or the like is performed with the power off, at the time of restarting, the work performed while the power is off is grasped, and post-processing of the work is preferably performed Can be executed.

<Other embodiments>
The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, etc.) of the system or apparatus reads the program. It is a process to be executed.
