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

  FIG. 1 is a system configuration diagram of this embodiment. The system includes a management center 10, a plurality of customer devices 12, 14,... And a sales / CE (Customer Engineer) base device 16, which are connected to each other via the Internet 18.

  The management center 10 includes a management server 101. The management server 101 collects the history (log) information of each printer from the customer apparatuses 12, 14,... And the sales / CE base apparatus 16 via the Internet 18.

  The customer apparatus 12 includes a log server 121 and a plurality of printers 122, 123,. The log server 121 collects history (log) information of each printer 122, 123,... And periodically transmits the collected history information to the management center 10 via the Internet 18. The same applies to the customer device 14, but depending on the customer, only one printer may be installed and there may be no log server. In other words, one or a plurality of printers are installed in the customer apparatus, and a log server may or may not exist. The history (log) information of each printer 122, 123 includes the operating status of each printer and error information. When there is no log server, the history information may be transmitted from the printer directly to the management center 10 via the Internet 18.

  The sales / CE base device 16 includes a plurality of terminals, and stores information on each printer 122, 123,... Of each customer device 12, 14,. Each terminal of the business / CE base device 16 transmits information of each printer 122, 123,... To the management center 10 via the Internet 18. The information of each printer 122, 123,... Is attribute information such as the installation location and installation environment of each printer, the type of business of the user (customer) who uses the printer, and the like. If there is information such as error information and error handling information of each printer 122, 123,..., These are stored as needed and transmitted to the management center 10.

  The management server 101 of the management center 10 includes a registration unit 1011, a classification / calculation unit 1012, a notification unit 1013, and a database (DB) 1014 as functional blocks. The registration unit 1011 acquires the history (log) information of each printer and the attribute information of each printer, and registers them in the database (DB) 1014 in association with each other. That is, the history information of each printer 122, 123,... Received from the log server 121 and the attribute information of each printer 122, 123,. Associate. For example, with regard to the printer 122, the history information including error information from the log server 121 and the attribute information from the terminal of the sales / CE base device 16 are associated with each other to obtain the attribute information of the printer 122 (installation location, installation environment, user's (Industry, printing amount) and history information (error information) are associated and registered in the database. The error information may include an error mode and a coping method, and the coping method may be transmitted as attribute information from the terminal of the sales / CE base device 16. The print amount is basically transmitted from the log server 121 as history information, but may be transmitted from the sales / CE base device 16 as attribute information as long as it is grasped by the sales / CE base device 16.

  The classification / calculation unit 1012 classifies these into a plurality of categories based on the attribute information registered in the database (DB) 1014. Further, the classification / calculation unit 1012 calculates the degree of occurrence of abnormality for each of the plurality of categories based on the history information registered in the database (DB) 1014. The classification / calculation unit 1012 registers the calculated abnormality occurrence degree in the database (DB) 1014 for each category. The notification unit 1013 notifies the printer belonging to the category of the possibility of abnormality via the Internet 18 based on the degree of abnormality occurrence for each category calculated by the classification / calculation unit 1012.

  In the present embodiment, the degree of occurrence of abnormality is calculated from the history information for each category. Therefore, even if a printer is newly introduced or a printer that is not yet in an abnormal state belongs to the same category. The possibility of occurrence of an abnormality can be notified as having the same degree of abnormality occurrence. The same applies to the case where the state or condition in which an abnormality occurs due to an unexplained factor.

  Each function block of the management server 101, that is, a function of acquiring attribute information and history information of each printer, a function of associating them with each other and registering them in the database (DB) 1014, a function of classifying them into categories, and the degree of occurrence of an abnormality for each category The function that calculates the error and the function that notifies the printer that belongs to the same category of the possibility of the occurrence of an abnormality according to the degree of the occurrence of the abnormality is realized by the CPU reading the processing program stored in the program memory and executing it sequentially Is done. Of course, at least any of the functions may be realized by hardware such as an ASIC.

  In this embodiment, the history information of each printer 122, 123,... Is transmitted from the log server 121 of the customer device 12, 14,... To the management server 101 of the management center 10. The log server 121 may transmit log information to the sales / CE base device 16, and the attribute information and history information may be collectively transmitted from the sales / CE base device 16 to the management server 101.

  FIG. 2 is an example of input information of the sales / CE base device 16. Information is sequentially input in time series for each customer name and printer (in the figure, the information is added sequentially from top to bottom). The information starts with the person who installed the printer, date / time, location, installation environment, type of business, number of machine pages, and amount of printing (planned). When maintenance work occurs, the maintenance person at that time, date / time, error content, and work The contents and the number of device pages are input. FIG. 2 shows that the photosensitive drum is nearly empty as the error content, and that the photosensitive drum has been replaced as the work content.

  FIG. 3 is an overall process flowchart of the present embodiment. The processing of this embodiment is roughly composed of three steps.

  The first step is a category classification step for each printer device (S101). In this step, the classification / calculation unit 1012 of the management center 10 reads each category information from the CE input information (see FIG. 2) for each printer device, and displays the category and category combination information to which the printer device belongs. Register in the log information management table. This category classification step is performed for all models.

  The second step is an occurrence count step for each error (S102). In this step, the classification / calculation unit 1012 of the management center 10 confirms whether or not an abnormality has occurred from the log of each printer device for each target error information, and sets the category information to which the printer device belongs as log information. The information is read from the management table and added to the target category portion in the count table for each category. For each error, the logs of all printer devices are searched and counted.

  The third step is an abnormality detection and notification step (S103). In this step, the notification unit 1013 of the management center 10 calculates the occurrence rate for each category from the count table for each category for each error information, and an abnormal state has occurred in a certain percentage or more of the printer devices. In addition, notification is made to the contact e-mail addresses of the users of all printer apparatuses belonging to the category, and the sales / CE in charge is also notified.

  The first to third steps are executed regularly (for example, every week or every month).

  On the other hand, independently of these steps, the registration unit 1011 of the management center 10 registers the log and CE input information for each printer in the DB 1014 of the management center 10, and logs related information about the apparatus, log, and input information to the log information. Register in the management table. The processing of the registration unit 1011 is performed periodically or as needed. Registration in the DB 1014 may be performed while each printer apparatus is not performing processing such as printing, or may be periodically registered by accessing the log server to acquire log information.

  Next, the first to third steps will be described in detail.

  FIG. 4 is a detailed flowchart of the category classification step for each printer.

  The classification / calculation unit 1012 sets the target device (S201), and accesses information on the target device from the log information table (S202).

Next, it is determined whether or not the device installation information has been updated with the sales / CE information (S203). If the device installation information has been updated (see “device installation” at the top of FIG. 2) (YES in S203), information is read from the sales / CE information regarding the region, environmental control, industry, and printing amount, and belongs The category information is extracted and registered in the category information of the log information table (S206). For category information extracted from logs and sales / CE information, two, three, and four combinations are registered in the category information of the log information table for each different category (S207).
For example, the category type is region, clean room, type of business, printing amount, and the target device is the region classification: Japan A
Classification with and without clean room: With clean room Industry classification: Newspaper Printing volume classification: In the case of a large amount, the categories to which it belongs are as follows: single and each combination.
(Single)
Japan A
Mass printing of newspapers with clean room (combination of two sets)
Japan A and clean room Japan A and newspaper Japan A and mass printing clean room and newspaper clean room and mass printing newspaper and mass printing (3 sets of combinations)
Japan A and clean room and newspaper Japan A and clean room and mass printing Japan A and newspaper and mass printing clean room and newspaper and mass printing (4 combinations)
Japan A, clean room, newspaper, mass printing

  On the other hand, if the device installation information has not been updated (NO in S203), or if it has been updated and the processing in S206 and S207 has been executed, then whether or not the processing has been completed for all the target devices. Is determined (S204). If all of them are not completed, the target is set to the next device and the processing from S202 is repeated. If all are completed, the processing moves to the next processing shown in FIG.

  FIG. 5 is an example of the created log information management table. Log information and sales / CE input information corresponding to each device are managed in association with each other, and category information belonging to each device is managed. For example, regarding the device “000001”, log information, registration location of sales / CE input information, log file name, sales / CE input file name are registered, and combinations of 2 groups, 3 groups, and 4 groups are categories. Registered as information.

  FIG. 6 shows an example of the count table for each category. A count table is created for each error information. The count value of the number of category target devices and the number of detected abnormalities is registered for each of all combinations for each element. In FIG. 6, the number of category target devices and the number of detected anomalies are indicated by initial values of 0.

  FIG. 7 is a detailed flowchart of the occurrence count step for each error.

  The classification / calculation unit 1012 counts the number of devices subject to each category for replacement parts of consumables or maintenance parts, and the number of devices determined to have a short replacement part life among those devices (S301).

  Further, the classification / calculation unit 1012 counts the number of target devices for each category and the number of devices in which errors have occurred even once among the occurrences of errors that should not occur (for example, hard errors). (S302).

  Further, the classification / calculation unit 1012 counts the number of devices that are targets for each category and the number of devices that are determined to have a high frequency of errors among the devices that may occur during printing (for example, jam) ( S303).

  8A and 8B are specific examples of S301, and are flowcharts of counting the number of photosensitive drums.

  First, the classification / calculation unit 1012 initializes the number of category target devices and the number of detected abnormality of all combinations for each element of the count table for each category as 0 for the photosensitive drum life (S401: refer to FIG. 6).

  Next, the target device is set (S402), the log information, sales / CE input information, and category information of the target device are read with reference to the log information table (S403), and all the category target devices to which the target device belongs are classified. 1 is added to the number (S404).

  Next, the management server 101 reads the log for each device from the latest information toward the past for a predetermined year in the past, for example, for the past two years (S405). The reason for limiting to the past predetermined year is that it is not necessary to count the abnormality once generated.

  Then, it is determined whether or not there is photosensitive drum replacement information (S406). If there is photosensitive drum replacement information, the number of device pages at the time of each photosensitive drum replacement is retrieved from the log information and read (S407). . Next, log information is further retrieved and read in the past (S408), and it is determined whether there is replacement information for another photosensitive drum (S409).

  If there is no replacement information for another photosensitive drum (NO in S409), the process proceeds to FIG. 8B, and the error information found is the first error after the introduction of the apparatus. The number of drum prints is set (S410).

  If there is another photosensitive drum replacement information (YES in S409), the flow advances to FIG. 8B, and the number of device pages at the time of photosensitive drum replacement is read from the log information. (S411).

  After setting the number of prints on the photosensitive drum in S410 or S411, it is determined whether the number of prints is less than 80% of the standard (S412). Here, the standard is the number of printed sheets corresponding to the life of the apparatus, and is the reference (or specification) number of printed sheets. If the number of printed sheets is less than 80% of the standard, an error has occurred before reaching the reference number of printed sheets due to some kind of abnormality, so an abnormality is detected, and 1 is added to the number of abnormality detected in all categories to which the target device belongs. (S413). And it transfers to the process of S415 mentioned later.

  On the other hand, when the number of printed sheets is 80% or more of the standard, it is determined whether or not the place viewed in the log is within two years from the present to the past without detecting any abnormality (S414). If it is within the year, the processing from S408 onward in FIG. 8A is repeated again. If it is not within two years, it is determined whether or not all abnormal information has been inspected (S415), and if it still remains, the processing from S403 in FIG. When the abnormality information is inspected, necessary information is similarly read for other errors, the abnormality determination process and the count process are performed, and are reflected in the category count table (S417).

  FIG. 8C is a specific example of S302 of FIG. 7, and is a flowchart for counting the number of fan abnormalities as hardware errors.

  The classification / calculation unit 1012 initializes the number of category target devices and the number of detected abnormalities of all combinations for each element of the category count table for the category to be inspected for fan abnormality as 0 (S418).

  Next, the target device is set (S419), the log information table is referred to, the log information, sales / CE input information, and category information of the target device are read (S410), and the category target device number of the category to which the target device belongs. 1 is added to (S421).

  Next, the log for each device is read from the server from the latest information to the past for the past two years (S422), and it is determined whether there is fan abnormality information (S423).

  If fan abnormality information exists, an abnormality is detected, and 1 is added to the number of abnormality detected in the category to which the device belongs (S424). If there is no fan abnormality information, it is determined whether all device information has been inspected without adding 1 to the number of abnormality detected (S425). If it still remains, the next device is targeted (S426), the processing from S420 is repeated, and if all device information is checked, the necessary information for the target error is read for all errors as well. Then, abnormality determination and count processing are performed (S427).

  8D and 8E are specific examples of S303 in FIG. 7, and are flowcharts for counting the number of jam errors.

  The classification / calculation unit 1012 initializes the number of category target devices and the number of detected abnormalities of all combinations for each element of the count table for each category for the inspection target category with respect to the jam error occurrence frequency as 0 (S428).

  Next, the target device is specified (S429), the log information table is referred to, the log information, the sales / CE input information, and the category information of the target device are read (S430), and the category target device number of the category to which the target device belongs. 1 is added to (S431).

  Next, the log for each device is read from the server up to the past two years from the latest information to the past (S432), and it is determined whether there is jam error information (S433).

  If there is no jam error information, it is determined whether or not all device information has been checked (S434). If there is still any information, the next device is targeted (S435), and the processing from S430 is repeated. If all device information has been inspected, information necessary for the target error is read out for other errors as well, and abnormality determination and count processing are performed (S436).

  On the other hand, if there is jam error information, the process proceeds to FIG. 8E, and the log is further read in the past (S437), and it is determined whether there is another jam error information (S438).

  If there is no error information of another jam, the error information found this time is the first error after the introduction of the device, so the number of device pages at the time of the current jam occurrence is set as the number of printed sheets indicating the jam occurrence frequency (S439).

  If there is error information of another jam, the number of device pages at the time of jam occurrence is read from the log information, and the difference between this time and the previous time is set as the number of printed sheets indicating the jam occurrence frequency (S440).

  After setting the number of prints in S439 or S440, it is determined whether the number of prints is less than 80% of the standard (S441). If it is less than 80%, an abnormality is detected and the number of detected abnormalities in the category to which this apparatus belongs is detected. 1 is added (S442). If the number of printed sheets is 80% or more of the standard, it is determined whether or not the place viewed in the log is within two years from the present to the past without detecting an abnormality (S443). Repeat the process. If it is two years or more, the process after S434 of FIG. 8D is repeated.

  As described above, the number of errors is counted in the category count table for each error.

  8F, 8G, and 8H are detailed flowcharts of the process of S103 of FIG. 3, that is, abnormality detection and notification. As an example, it is a case of abnormality detection of the photosensitive drum.

  The notification unit 1013 sets a target abnormal state (S501). In the photosensitive drum, the abnormal state is the life of the photosensitive drum.

  Next, (abnormality detection number) / (category target device number) is calculated for the target range without combination (single) (S502). “No combination” (single) means “Japan A”, “With clean room”, and the like.

  Then, it is determined whether or not the calculation result is equal to or greater than a specified value of the target error (S503). If the calculation result is equal to or greater than the specified value, the device belonging to the target range is notified (S504). In addition, in order to eliminate duplicate notification, the current range is excluded from the target in the confirmation after the next two combinations. If the calculation result is less than the specified value, it is determined whether or not all combinations have been confirmed (S505), and if they still remain, the next range is targeted (S506), and the processing after S502 is repeated to confirm all. If it is, then (abnormality detection number) / (category target device number) is calculated for the range of two combinations (S507). The two combinations are, for example, “Japan B and clean room”.

  Then, as in the case of no combination (single), it is determined whether or not the calculation result is equal to or greater than the specified value of the target error (S508). If the calculation result is equal to or greater than the specified value, the process proceeds to FIG. 8G to notify the device belonging to the target range (S509). In addition, this range is excluded from the target in the confirmation after the next three combinations. If the calculation result is less than the specified value, the process proceeds to FIG. 8G to determine whether or not all the two combinations have been confirmed (S510). If the calculation result still remains, the process is repeated for the next range (S511). If all the items have been confirmed, (abnormality detection number) / (category target device number) is calculated for the target range of the three combinations (S512). The three combinations are, for example, “Japan B, no clean room, and newspaper”.

  Then, it is determined whether or not the calculation result is equal to or greater than the specified value of the target error (S513). If the calculation result is equal to or greater than the specified value, the device belonging to the target range is notified (S514). Also, the current range is excluded from the target in the confirmation after the next four combinations. If the calculation result is less than the specified value, it is determined whether or not all three combinations have been confirmed (S515). If the calculation result still remains, the process is repeated for the next range (S516). If all are confirmed, the process proceeds to FIG. 8H.

  In FIG. 8H, (abnormality detection number) / (category target device number) is calculated for the range of four combinations (S517).

  Then, it is determined whether or not the calculation result is equal to or greater than the specified value of the target error (S518). If the calculation result is equal to or greater than the specified value, the device belonging to the target range is notified (S519). If the calculation result is less than the specified value, it is determined whether or not all four combinations have been confirmed (S520). If the calculation result still remains, the process is repeated for the next range (S521). When all the items have been confirmed, the next abnormality target is set and the abnormality occurrence rate is similarly confirmed. If it is equal to or more than the specified value, the device belonging to the target range is notified (S522). If all abnormalities are notified, the process is terminated (S523).

  In the processes of FIGS. 8F to 8H, the specified value can be adaptively set according to the target error. For example, it is set to 20% in the case of the life of the photosensitive drum.

  FIG. 9 shows a specific example of the processing of FIGS. 8F to 8H. Assume a situation in which there are many devices in which the life of the photosensitive drum is shorter than the original life due to high temperature and humidity. It is assumed that 20% is set as the specified value. In FIG. 9, the occurrence rate of all categories, that is, the occurrence rate = {number of detected anomalies} / category target device number is shown in%.

Since the incidence is 20% or more in the category of India A area and no clean room, the possibility of abnormality is notified to all devices belonging to this category. In this case, the occurrence rate is less than 20% in the category of “India A area and no clean room”, “Newspaper and mass printing”, “India A area and no clean room”, and “Form printing” category. Notification is made in the category of “India A area and no clean room”. The content of the notification is arbitrary, but for example,
“In India area A, and without a clean room, the life of the photosensitive drum tends to decrease, so be careful.”
Etc.

  In addition, there is a category with an incidence rate exceeding 20%, such as “India A area and no clean room”, and “Newspaper and occasional mass printing 1”, etc. Anomaly detection in the category “India A area and no clean room” Therefore, in the category with more combinations, the notification is not repeated.

  In addition, since the occurrence rate is 20% or more even in the category “Japan B region and no clean room” and “sometimes mass printing 1”, the possibility of abnormality is notified to all devices belonging to this category.

  Similarly, since the occurrence rate is 20% or more in the category “newspaper and other areas” in “Japan B area and no clean room”, the possibility of abnormality is notified to all devices belonging to this category. .

  In this way, the notification unit 1013 calculates the occurrence rate for each category, and if it is equal to or greater than the specified value, notifies all devices belonging to that category of the possibility of abnormality, but is installed inside or around the device. When the information of the acquired environmental sensor can be acquired, the acquired environmental information may be used for categorization.

For example, a temperature sensor and a humidity sensor are installed outside the printer device, and information from these sensors is recorded in a log. From this information, it is classified into normal (range of specifications), high temperature and high humidity, high temperature and low humidity, low temperature and high humidity, and low temperature and low humidity. Errors that are relatively likely to occur, such as jams, may be divided into categories by combinations of region, environmental information, and industry. The content of the notification is, for example,
“In a high temperature and high humidity environment, if the target print amount is XX or higher, the life of the photosensitive drum tends to decrease.
Etc.

Even when no environmental sensor is installed, categories may be classified by month information in January, February,..., December instead of environmental information. Thereby, even if the environmental sensor is not installed, the influence of the season and the like can be grasped. By using month information, the influence of periodic or human factors can be grasped. Thereby, information for grasping in which season the replacement of the photosensitive drum is likely to occur is obtained, and inventory management by CE can be more appropriately performed. For example, as a notification using month information,
“In June and July, if the target print amount is YY or more, the life of the photosensitive drum tends to decrease.
