First, the configuration will be described.
As shown in FIG. 1, the image forming apparatus A in this embodiment is connected to a management server B via a network N.
The image forming apparatus A is a printer, a copier, a facsimile, or a complex machine of these.
The management server B includes a large-capacity memory, and holds replacement guide information for parts used in the image forming apparatus A in the memory. The replacement guide information includes information on images (moving images and still images) describing the replacement procedure, and guide sound information. The management server B manages the inventory status of each component.

FIG. 2 shows a functional configuration of the image forming apparatus A.
As shown in FIG. 2, the image forming apparatus A includes an image reading unit 2, an operation unit 3, an image forming unit 4, a display unit 5, a sound output unit 6, a main body unit 10, and the like.
Hereinafter, each component will be described.

  The image reading unit 2 includes a scanner 21, an ADF (automatic paper feeding mechanism), and the like. The image reading unit 2 exposes and scans the document surface placed on the document table by the scanner 21, and reads the document image by performing photoelectric conversion. An analog image signal of the read document image is output to the reading processing unit 13 of the main body unit 10.

  The operation unit 3 includes an operation display 31 that is a touch panel and other operation key groups (not shown). The operation unit 3 outputs an operation signal input from the operation key group or the operation display 31 to the control unit 11.

  The image forming unit 4 includes a unit including an exposure unit, a photosensitive drum, a developing unit, a fixing device, a paper feeding unit, and the like, and an image input from the writing processing unit 18 in accordance with an instruction from the control unit 11. Based on the data, an image is formed on a sheet. In the image formation, first, an electrostatic latent image is formed on the surface of the photosensitive drum by the exposure unit. Then, the electrostatic latent image on the photosensitive drum is developed with the toner of the developing unit to form a toner image, and the toner image is transferred to the paper fed from the paper feeding unit. Thereafter, the fixing device performs fixing processing.

  The display unit 5 displays on the operation display 31 an operation screen for inputting image forming conditions and post-processing conditions, a guide screen related to a part replacement guide, and the like according to a display signal input from the control unit 11.

  The sound output unit 6 includes a sound processing unit, a speaker, and the like, and outputs a notification sound, a guide sound, and the like.

  As shown in FIG. 2, the main body unit 10 includes a control unit 11, memories 121 and 122, a reading processing unit 13, a compression IC (Integrated Circuit) 14, a DRAM (Dynamic Random Access Memory) control IC 15, an image memory 16, and a decompression IC 17 The writing processing unit 18 and the communication unit 19 are provided.

  The control unit 11 performs various calculations and centrally controls the operation of each unit in cooperation with a program stored in the memory 122.

The memory 121 is a RAM or the like. The memory 121 is used as a working memory by the control unit 11.
The memory 122 is a hard disk or the like, and is used as a storage memory. In addition to each program, the memory 122 stores parameters used for executing the program, processed data, and the like.

  For example, the memory 122 stores a component management table T as shown in FIG. The component management table T includes a code of each component used in the image forming apparatus A, a name, a usage frequency counted for the component, a threshold value indicating a replacement time for each component, a threshold value indicating an acquisition time of replacement guide information, a past The required time required for the replacement, the basic required time predetermined as the required time required for the replacement, and the replacement frequency are stored.

The replacement time refers to the time at which parts should be replaced, and the threshold value indicating the replacement time is a threshold for use frequency for determining whether or not the replacement time has been reached. That is, it is determined that the replacement time has been reached when the counted usage frequency reaches a threshold value indicating the replacement time.
The acquisition time of the replacement guide information is a time before the replacement time, and a time when the replacement guide information should be acquired from the management server B. The threshold value indicating the acquisition time is a use frequency threshold value for determining whether or not the acquisition time is reached from the use frequency. The point that it is determined that the acquisition time has been reached when the counted usage frequency reaches the acquisition time threshold is the same as in the replacement time.

  It should be noted that the threshold value indicating the replacement time is experimentally obtained as a use frequency value that requires replacement, and is set in the component management table T as a threshold value. In addition, the threshold value indicating the replacement guide information acquisition time may be set as appropriate as the value of the use frequency corresponding to the time before the replacement time. Preferably, a use frequency value corresponding to a time close to the replacement time is set. This is because the replacement guide information is acquired at a timing when replacement is required. For example, when the usage frequency that is the threshold of the replacement time is “200000”, the usage frequency that is the threshold of the acquisition time may be “190000” that is close to the threshold of the replacement time (corresponding to 95% of the threshold).

The time required for the past exchange is the time required when the exchange was performed in the past. On the other hand, the basic required time is a predetermined time that is predetermined as a required time estimated to be required for normal replacement.
The exchange frequency is the cumulative number of exchanges performed in the past.

  The DRAM control IC 15 controls the compression processing of the image data by the compression IC 14 and the decompression processing of the compressed image data by the decompression IC 17 in accordance with an instruction from the control unit 11 and performs input / output control of the image data to the image memory 16. For example, when storage of image data read by the image reading unit 2 is instructed, the compression processing of the image data input from the reading processing unit 13 is executed by the compression IC 14, and the compressed image data is compressed in the image memory 16. It is stored in the memory 16a. Further, when forming an image, the compressed image data is read from the compression memory 16a, and decompressed by the decompression IC 17 and stored in the page memory 16b. Next, uncompressed image data is read from the page memory 16 b and output to the writing processing unit 18.

  The image memory 16 includes a compression memory 16a and a page memory 16b configured by DRAM. The compression memory 16a is a memory for storing compressed image data, and the page memory 16b is a memory for temporarily storing uncompressed image data.

The decompression IC 17 performs decompression processing on the input compressed image data.
The writing processing unit 18 generates data for image formation based on the image data input from the DRAM control IC 15 and outputs the data to the image forming unit 4.

  The communication unit 19 includes a communication interface such as a network interface card, and communicates with an external device. For example, the communication unit 19 exchanges information with the management server B via the network N.

Next, the operation will be described.
In the present embodiment, the image forming apparatus A determines the replacement timing of each component and the acquisition timing for acquiring replacement guide information from the usage frequency, and replaces the component from the management server B before reaching the acquisition timing, that is, the replacement timing. Get guide information (download).
FIG. 4 is a flowchart showing the flow of processing performed in the image forming apparatus A and the management server B at that time. This process is repeatedly executed, for example, when the image forming apparatus A is turned on or at predetermined time intervals.

As shown in FIG. 4, in the image forming apparatus A, in the process of image formation, the control unit 11 counts the frequency of use of each component (step S1). The usage frequency is counted in units corresponding to the usage mode of each part. For example, if the component is a band electrode, the usage time is counted (timed) in units of time, whereas if it is a drum cartridge, the number of sheets on which image formation has been performed is counted. Note that the same component may be counted in different units. For example, in the case of a drum cartridge, the frequency of use is counted separately from the number of sheets in units of the distance that the drum rotates. This is for judging the replacement time in many ways.
The control unit 11 writes the counted use frequency value in the component management table T of the memory 122.

  Next, the control unit 11 compares the use frequency with the threshold value for obtaining the replacement guide information, and determines whether there is a component whose use frequency exceeds the threshold value, that is, a component that has reached the acquisition time for the replacement guide information (step). S2). When the usage frequency is counted in a plurality of different units, it may be determined whether or not the acquisition time has been reached using the usage frequency of any unit. If there is no part whose usage frequency exceeds the threshold value, none of the parts has reached the acquisition time (step S2; N), and the process is terminated.

  On the other hand, when there is a part whose usage frequency exceeds the threshold value, since the replacement guide information acquisition time has come (step S2; Y), the communication unit 19 transmits request information for requesting the replacement guide information to the management server B. (Step S3). The request information includes information on the IP address of the image forming apparatus A, the serial number, the language code used, and the part code that requires replacement guide information.

  When the management server B receives the request information from the image forming apparatus A, the management server B creates replacement guide information based on the request information (step S4). First, the management server B determines from the serial number of the image forming apparatus A whether the image forming apparatus A is a genuine product and where the destination is. If the product is a genuine product, the replacement guide information corresponding to the destination, the language code used, and the part code is created. That is, the corresponding model and the code of the component used for the model are specified from the destination, and the guide image corresponding to the model and the component code is read from the memory. In addition, information on the guide voice corresponding to the language code used is read from the memory and used as exchange guide information.

  Next, in order to respond to the request for obtaining the replacement guide information, the management server B uses the IP address included in the request information to obtain the created replacement guide information and information about the serial number of the image forming apparatus A that made the request. The image is transmitted to the image forming apparatus A (step S5).

  When the image forming apparatus A receives the replacement guide information and the like, it temporarily stores it in the working memory 121 (step S6). Then, the control unit 11 determines whether or not there is free space in the storage memory 122 (step S7). If there is enough free space to store the replacement guide information (step S7; Y), it is stored in the storage memory 122 (step S8), and this process is terminated. If there is not enough free space (step S7; N), the process ends without saving.

  If the image is not stored in the storage memory 122, the replacement guide information stored in the work memory 121 may be deleted when the image forming apparatus A is turned off. In this case, since the processing described above is executed at the next power-on timing, etc., the replacement guide information is acquired again from the management server B at that time.

The replacement guide information acquired as described above is used when executing the replacement guide. The replacement guide can be executed in accordance with a user instruction operation. At that time, processing performed by the image forming apparatus A will be described with reference to FIG.
As shown in FIG. 5, in the image forming apparatus A, first, the control unit 11 acquires the replacement guide information, that is, the component that has reached the acquisition time (the component whose use frequency exceeds the acquisition time threshold). The presence or absence is determined (step S11). If there is no such part (step S11; N), this process is terminated.

  On the other hand, when there is a part that has reached the acquisition time (step S11; Y), the control unit 11 displays a replacement procedure method button on the display unit 5 (step S12). The exchange procedure method button is a button for the user to instruct execution of the exchange guide. In response to the operation of the exchange procedure method button, the image forming apparatus A performs an exchange guide process, that is, a process for displaying an image showing the exchange procedure on the display unit 5 and an audio output unit 6 outputs a guide sound in accordance with the image. Will be processed.

  The exchange procedure method button may be displayed on the operation standby screen d1 as indicated by reference numeral k1 in FIG. 6, for example. Further, as shown in FIG. 7, it may be displayed on the image forming condition setting screen d2 or other toolbars. The display of the replacement procedure method button k1 allows the user to know the presence of a part that has reached the replacement guide information acquisition time. In addition, when the user wants to learn the exchange procedure before reaching the exchange time, the exchange procedure method button k1 may be operated.

  In the image forming apparatus A, when the replacement procedure method button k1 is operated (step S13; Y), the control unit 11 determines the display order when displaying the component information as a list based on the component management table T (step S13). S14). The display order is determined when there are a plurality of parts that have reached the acquisition time. The display order can be determined by the replacement frequency, the replacement time, and the like. For example, since parts with low replacement frequency can be expected to be parts unaccustomed to replacement by the user, it is possible to prompt the user to view the replacement guide first for parts with unfamiliar parts by changing the display order in order of low replacement frequency. . Alternatively, since it is more necessary to look at the replacement guide as the parts are closer to the replacement time, the display order may be set in the order closer to the replacement time (the order in which the difference between the use frequency and the threshold indicating the replacement time is smaller). .

  Next, processing is performed to acquire inventory information indicating the current inventory status of parts from the management server B (step S15). Specifically, the control unit 11 creates request information for requesting inventory information about a part that has reached the replacement guide information acquisition time, and transmits the request information to the management server B by the communication unit 19. In the management server B, according to the request information, inventory information of the parts related to the request is created and transmitted to the image forming apparatus A, so that the image forming apparatus A can acquire the inventory information. The inventory information includes at least information on the presence / absence of parts in stock, and information on the remaining number when there is inventory.

When the inventory information is acquired, the control unit 11 changes the display order according to the inventory information, and then causes the display unit 5 to display a list of component information according to the changed display order (step S16).
For example, in the display order that has already been determined, the parts that are in stock and the parts that are not in stock are rearranged. In this way, since there is a possibility that parts that are not in stock may not be replaced immediately, the user can be prompted to replace the replaceable parts first by deferring the display order.

FIG. 8 shows a list screen d3 as a display example.
As shown in FIG. 8, in the list screen d3, the control unit 11 follows the display order after the change in order that the “drum cartridge / Y” part that is in stock first, and the “toner / K” part that is not in stock follows. The parts information is displayed in a list so that they are in order. In addition, as part information, an icon d31 indicating a part that is about to be replaced, a guideline d32 for replacement time, a time required for replacement d33, and inventory d34 are displayed.

  The icon d31 is an icon for selecting a part. The control unit 11 displays the name of the part on the icon d31 as a part that is close to the replacement time for the part that has reached the replacement guide information acquisition time.

  The replacement time standard d32 is information of a standard indicating how much use will reach the replacement time. Based on the difference between the current use frequency and the threshold value indicating the replacement time, the control unit 11 calculates the remaining use frequency that can be used until the replacement time, based on the component management table T, and calculates this until the replacement time. Use as reference information. In the example of FIG. 3, since the usage frequency (unit is the number of sheets) of the parts of the drum cartridge / Y is “1976655” and the replacement time threshold is “200000”, the remaining “2345” sheets are used. Can be used. Therefore, information “replace with 2345 prints” is displayed on the list screen d3 as the replacement time standard d32.

  The replacement required time d33 is information on a guideline for the required time for replacement, and is obtained based on the component management table T. For parts that have been replaced in the past (parts with a replacement frequency of 1 or more), information on the required time for replacement required in the past replacement is stored in the part management table T, so that information is displayed. . On the other hand, for the parts to be replaced for the first time (parts with a replacement frequency of 0), the basic required time information stored in the parts management table T is read and displayed.

  The inventory d34 is inventory information acquired from the management server B. That is, since the stock information includes information on the presence / absence of the stock, this is displayed. If there is a stock, the remaining number of information may be displayed.

  The user refers to the information on the parts displayed on the list screen d3, and if there is a part for which the replacement guide is to be executed, the user may select and operate the icon d31 for the part.

  When the icon d31 of any part is operated, the control unit 11 determines whether or not the replacement guide information for the part is stored in the storage memory 122 (step S17). If it is not stored (step S17; N), this process is terminated. If it is stored (step S17; Y), the control unit 11 uses the storage memory 122 for replacement guide information for work. Is read into the memory 121 (step S18).

Next, the control unit 11 causes the display unit 5 to display an image related to the replacement guide using the replacement guide information read to the memory 121. If there is a guide voice, it is output by the sound output unit 6 (step S19), and this process ends.
FIG. 9 shows a guide screen d4 as an example of the display.
As shown in FIG. 9, an image d41 illustrating the part replacement procedure is displayed on the guide screen d4. In the guide screen d4, the control unit 11 reads out information on the basic required time d42 and the past required time d43 from the component management table T and displays it. Further, a list button k2 for instructing switching display from the guide screen d4 to the original list screen d3 is displayed.

Thereafter, when the parts are actually replaced, the operation mode of the image forming apparatus A shifts to the replacement mode, and the control unit 11 executes the replacement guide process again. When the replacement of the parts is performed, the replacement mode is terminated and the mode is changed to the normal mode.
When the control unit 11 receives the control signal indicating that the replacement has been performed from any of the constituent units, the control unit 11 writes the replacement frequency for the replaced component in the component management table T by incrementing it once. Further, the control unit 11 measures the time from the transition to the replacement mode to the return to the normal mode, and writes this in the parts management table T as the past required time. Further, the control unit 11 resets the use frequency count value and starts counting again from the initial value 0.

Next, a case where the replacement guide process is executed in the power saving mode will be described with reference to FIG. In this case, a replacement guide is provided for a component that has been acquired for replacement guide information without any user operation.
As shown in FIG. 10, first, the control unit 11 determines whether or not there is a part that has reached the time for obtaining replacement guide information (step S31). Next, after determining the display order of the component information in the list display (step S32), the control unit 11 acquires inventory information from the management server B (step S33). Note that steps S31 to S33 have the same contents as the processes of steps S11, S14, and S15 shown in FIG.

  Subsequently, the control part 11 changes a display order according to the acquired inventory information (step S34). For example, in the display order that has already been determined, the parts that are in stock and the parts that are not in stock are rearranged.

  Next, the control unit 11 determines whether or not the replacement guide information of the part that has reached the acquisition time is stored in the storage memory 122 (step S35). If not stored (step S35; N), the process proceeds to step S38. If stored (step S35; Y), the control unit 11 stores the replacement guide information from the storage memory 122. The data is read out to the working memory 121 (step S36).

Next, the control unit 11 causes the display unit 5 to display an image related to the replacement guide (see FIG. 9) using the replacement guide information read to the memory 121 (step S37). If there is a guide voice, the sound output unit 6 outputs it.
If there is another part that has reached the acquisition time (step S38; Y), the target is changed to another part (step S39), and the process proceeds to step S35. That is, if the replacement guide information is stored for other parts, the voice guide is executed.

If there is no other part that has reached the acquisition time (step S38; N), this process is terminated.
Note that if there is any operation due to an interrupt during the above process, the power saving mode is restored to the normal power mode, and an operation screen for copying, scanning, etc. is displayed on the display unit 5. Become.

  As described above, according to the present embodiment, the use frequency is counted, the replacement time is determined from the use frequency, and the replacement guide information is acquired from the management server B before the replacement time is reached. As a result, the replacement guide information for all the components need not be stored in the memory of the image forming apparatus A in advance, and the replacement guide information for the necessary components can be acquired when necessary. High cost can be avoided. In addition, the replacement guide information can be used to process the replacement guide before the replacement time is reached, and the user can learn the replacement procedure in advance. Therefore, parts can be replaced more smoothly and efficiently.

  The replacement guide is performed not only when the replacement is actually performed, but also according to the user's execution instruction by operating the replacement procedure method button k1, so that the user can execute the replacement guide when he / she wants to learn.

  In addition, if there is a part that has reached the time for obtaining replacement guide information even in the power saving mode, the replacement guide processing is performed using the replacement guide information. Replacement guide can be performed.

  For the parts that have reached the replacement guide information acquisition time, the parts information is displayed in a list, so that the user can easily grasp the presence of the parts that have acquired the replacement guide information.

  Further, since the information on the replacement time standard d32 is displayed for each part in the list display, the user can easily grasp in advance how much use will reach the replacement time.

  In addition, the time required for past replacement is displayed for parts that have been replaced in the past, and the basic required time is displayed for parts that are replaced for the first time. Can be grasped in advance.

  Moreover, since the stock status is displayed, the user can grasp in advance whether or not the parts can be ordered immediately.

  Also, the parts information is displayed by rearranging the display order according to the stock status, replacement frequency, degree of approach until replacement time, and the like. Accordingly, it is possible to provide the component information to the user in the display order corresponding to various applications, such as the order in which the user can easily replace the parts or the order in which the necessity of replacement is high.

In addition, the said embodiment is a suitable example of this invention, and is not limited to this.
For example, in the above embodiment, a threshold indicating the acquisition time of the replacement guide information is set, and when the usage frequency reaches this, it is determined that the replacement time is reached and the replacement guide information is acquired. Other methods may be used as long as the replacement time is determined from the use frequency and the replacement guide information can be acquired before the replacement time is reached. For example, the replacement guide information can be acquired when the difference between the threshold value indicating the replacement time and the counted usage frequency is equal to or less than a predetermined value.

  The replacement guide information stored in the memory 122 may be deleted from the memory 122 after replacement of the parts, and the replacement guide information may be acquired and stored again when the next replacement time is approaching. According to this, the used capacity of the memory 122 can be suppressed. Further, it is possible to obtain a new replacement guide information even when the replacement guide information is updated.

  Moreover, although the example which used the memory 122 as a computer-readable medium of the program which implement | achieves the process of this embodiment was disclosed, it is not limited to this example. As other computer-readable media, a non-volatile memory such as a flash memory and a portable recording medium such as a CD-ROM can be applied. Also, a carrier wave can be applied as a medium for providing program data via a communication line.
