This application claims priority to Japanese Patent Application No. 2019-203322, filed on Nov. 8, 2019, the entire contents of which are hereby incorporated by reference into the present application.
The art disclosed herein relates to a server configured to externally send a notification for prompting an order of a new consumable article for a printer.
An order assisting system for consumable articles, which is provided with a printer, a user terminal, a server, an inventory management terminal, and a distribution center terminal, is known. When a remaining amount of a consumable article in the printer becomes small, the printer sends information indicating that the remaining amount of the consumable article has become small to the server through the user terminal. When receiving this information from the user terminal, the server sends information including a device name of the printer and the like to the inventory management terminal. When receiving this information from the server, the inventory management terminal updates a consumable article stock quantity stored in the inventory management terminal. Then, the inventory management terminal sends a warning e-mail to the user terminal when the consumable article stock quantity becomes equal to or less than a warning stock quantity. As such, the user can access an order website notified in the warning e-mail to order a consumable article.
A new consumable article may not be ordered due to a reason that the user has not read the warning e-mail, for example. In such case, consumable article(s) possessed by the user may become insufficient.
The disclosure herein provides art for suppressing insufficiency in consumable article(s) possessed by a user.
A server disclosed herein may comprise a controller configured to: receive consumable article information including usage information from an external device, the usage information being information related to a current used amount of a consumable article that is currently attached to a printer for printing; in a case where the consumable article information is received from the external device, determine by using the usage information included in the consumable article information whether a first notification condition is satisfied, the first notification condition being related to an order of a new consumable article; in a case where it is determined that the first notification condition is satisfied, send by using a first communication method a first notification for prompting the order of the new consumable article to external; after the first notification has been sent to external, determine whether a second notification condition is satisfied, the second notification condition corresponding to that the new consumable article has not been ordered in response to the sending of the first notification; and in a case where it is determined that the second notification condition is satisfied, send by using a second communication method that is different from the first communication method a second notification for prompting the order of the new consumable article to external.
A control method, a computer program, and a computer-readable recording medium storing the computer program for realizing the aforementioned server are also novel and useful. Further, a communication system that comprises the aforementioned server and the external device is also novel and useful.

(Registration Process;
Next, a registration process will be described with reference to
In an initial state of
When accepting an operation for activating the service application 138 from the user in T10, the terminal device 100 activates the service application 138 in T12 and sends a login screen data request to the management server 200 in T14.
When receiving the login screen data request from the terminal device 100 in T14, the management server 200 sends login screen data to the terminal device 100 in T16.
When receiving the login screen data from the management server 200 in T16, the terminal device 100 displays a login screen on the display unit 114 in T18. Then, when accepting an operation of inputting the user name UN and the password PW from the user in T20, the terminal device 100 sends a login request including the user name UN and the password PW to the management server 200 in T22.
When receiving the login request from the terminal device 100 in T22, the management server 200 determines that authentication is successful because the combination of the user name UN and the password PW included in the login request is in the user table 238. In this case, the management server 200 sends setting screen data to the terminal device 100 in T30.
When receiving the setting screen data from the management server 200 in T30, the terminal device 100 displays a setting screen on the display unit 114 in T32. The setting screen is a screen for inputting the printer number of a printer that is a target of the shipping service. When accepting an operation of inputting the printer number PS1 from the user in T34, the terminal device 100 sends the printer number PS1 to the management server 200 in T36.
When receiving the printer number PS1 from the terminal device 100 in T36, the management server 200 sends threshold setting screen data to the terminal device 100 in T40.
When receiving the threshold setting screen data from the management server 200 in T40, the terminal device 100 displays a threshold setting screen on the display unit 114 in T42. The threshold setting screen is a screen for allowing the user to input threshold information. When accepting an operation of inputting threshold information “30” from the user in T44, the terminal device 100 sends the threshold information “30” to the management server 200 in T46.
When receiving the threshold information “30” from the terminal device 100 in T46, the management server 200 identifies the logged in user name UN, and sends to the shipping server 300 in T48 the identified user name UN, the printer number PS1 received in T36, and the threshold information “30” received in T46.
When receiving the user name UN, the printer number PS1, and the threshold information “30” from the management server 200 in T48, the shipping server 300 associates the user name UN, the printer number PS1, and the threshold information “30” with each other and stores the same in the cartridge table 340 in T50.
In T60 of
When receiving the consumable article information request from the terminal device 100 in T60, the printer 10 identifies the cartridge number CS1 of the cartridge 20a currently attached to the printer 10 and the remaining amount information RQn in the memory 34. Then, in T62, the printer 10 sends to the terminal device 100 consumable article information including the printer number PS1, the cartridge number CS1, and the remaining amount information “40”.
When receiving the consumable article information from the printer 10 in T62, the terminal device 100 sends the consumable article information to the shipping server 300 via the management server 200 in T64. As aforementioned, the communication I/F 16 of the printer 10 is not connected to the Internet 8. That is, the printer 10 cannot send the consumable article information to the management server 200 via the Internet 8. In the present embodiment, the terminal device 100 receives the consumable article information from the printer 10 and sends this consumable article information to the management server 200. As such, the management server 200 can receive the consumable article information even though the printer 10 cannot access the Internet 8. As a result, the user of the printer 10 can receive the shipping service provided by the management server 200 and the shipping server 300.
When receiving the consumable article information from the management server 200 in T64, the shipping server 300 identifies the printer number PS1 in the consumable article information. Then, in T66, the shipping server 300 stores, in the cartridge table 340, the cartridge number CS1 in the consumable article information, a model number “BK01” of the cartridge that can be attached to the printer 10 identified by the cartridge number CS1, and the remaining amount information “40” in the consumable article information in association with the printer number PS1 in the cartridge table 340 (see T50 of

Next, the first notification process executed in S30 of
In S112, the CPU 332 determines whether the cartridge number in the consumable article information received in S10 matches the cartridge number in the target cartridge information. The CPU 332 proceeds to S120 in a case of determining that the cartridge number in the consumable article information matches the cartridge number in the target cartridge information (YES in S112). On the other hand, the CPU 332 proceeds to S130 in a case of determining that the cartridge number in the consumable article information does not match the cartridge number in the target cartridge information (NO in S112).
In S120, the CPU 332 stores the remaining amount information in the consumable article information received in S10 as the remaining amount information of the target cartridge information.
In S130, the CPU 332 determines whether the error notification flag in the target cartridge information is “ON” or not. The CPU 332 proceeds to S132 in a case of determining that the error notification flag is “ON” (YES in S130). On the other hand, the CPU 332 skips S132 and proceeds to S134 in a case of determining that the error notification flag is “OFF” (NO in S130).
In S132, the CPU 332 changes the error notification flag in the target cartridge information from “ON” to “OFF”.
In S134, the CPU 332 stores the cartridge number and the remaining amount information in the consumable article information received in S10 as the cartridge number and the remaining amount information of the target cartridge information.
In S140, the CPU 332 determines whether the remaining amount indicated by the remaining amount information in the consumable article information received in S10 is no greater than a threshold indicated by the threshold information in the target cartridge information. The CPU 332 proceeds to S142 in a case of determining that the remaining amount is equal to or less than the threshold (YES in S140). On the other hand, the CPU 332 terminates the process of
In S142, the CPU 332 sends an e-mail including the first order notification to the terminal device 100. Specifically, the CPU 332 firstly identifies the user name in the target cartridge information and then identifies the e-mail address associated with the identified user name in the user table 338. Then, the CPU 332 sends an e-mail including the first order notification to the identified e-mail address. As described, the e-mail is sent to the terminal device 100 which is capable of receiving e-mails addressed to the identified e-mail address.
In S144, the CPU 332 changes the order notification flag in the target cartridge information from “OFF” to “ON”.
In S146, the CPU 332 changes the unshipped flag in the target cartridge information from “OFF” to “ON”. When S146 is completed, the CPU 332 terminates the process of
In the case of determining NO in S110, the CPU 332 determines in S150 whether the error notification flag in the target cartridge information is “OFF” or not. The CPU 332 proceeds to S152 in a case of determining that the error notification flag is “OFF” (YES in S150). On the other hand, the CPU 332 terminates the process of
In S152, similar to S142, the CPU 332 uses the target cartridge information and the user table 338 to identify the e-mail address to which an e-mail is to be sent and then sends an e-mail including the error notification to the identified e-mail address. This error notification includes a message indicating that the cartridge currently attached to the printer 10 is not covered by the shipping service. As such, the user of the printer 10 can acknowledge that the shipping service is not available currently.
In S154, the CPU 332 changes the error notification flag in the target cartridge information from “OFF” to “ON”.
In S156, the CPU 332 deletes the cartridge number and the remaining amount information in the target cartridge information. When S156 is completed, the CPU 332 terminates the process of

(Specific Cases;
Next, specific cases realized by the processes of
(Case A;
In Case A, a new cartridge is ordered in response to the first order notification having been sent from the shipping server 300 to the terminal device 100. Case A will be described with reference to
When determining that the first predetermined time has elapsed since the consumable article information request was sent to the printer 10, the terminal device 100 sends the consumable article information request to the printer 10 in T110. T112 and T114 are respectively similar to T62 and T64 in
When receiving the consumable article information from the management server 200 in T114 (YES in S10 of
The present case assumes a situation in which printing is executed in the printer 10 before the first predetermined time elapses from the time when the terminal device 100 sent the consumable article information request to the printer 10 in T110. When printing is executed using the cartridge 20a in T130, the printer 10 calculates a used amount “15” of the ink in the cartridge 20a and subtracts the calculated used amount “15” from the remaining amount “40” indicated by the remaining amount information RQn to update the remaining amount indicated by the remaining amount information RQn to “25”.
After this, when determining that the first predetermined time has elapsed since the consumable article information request was sent in T110 to the printer 10, the terminal device 100 sends the consumable article information request to the printer 10 in T140. T140 to T146 are similar to T110 to T116 respectively, except that the remaining amount information in the consumable article information is different. When receiving the status confirmation from the terminal device 100 in T146 (S24), the shipping server 300 determines that the order notification flag in the cartridge information CI1 is “OFF” (NO in S26), determines that the consumable article information received in T144 includes the cartridge number CS1 (YES in S110 of

When accepting an operation for displaying the e-mail received from the shipping server 300 from the user in T162, the terminal device 100 displays a received e-mail screen based on the first order notification (first order notification screen) on the display unit 114 in T164. This screen includes a message for prompting an order of a new cartridge and an order URL “http://server.co.jp/UN” to be accessed to order a new cartridge. Then, when accepting an operation for accessing the order URL “http://server.co.jp/UN” from the user in T166, the terminal device 100 sends to the shipping server 300 in T168 an access request including the order URL “http://server.co.jp/UN” as a destination URL.
When receiving the access request from the terminal device 100 in T168 (YES in S50 of
When receiving the order confirmation screen data from the shipping server 300 in T172, the terminal device 100 displays an order confirmation screen on the display unit 114 in T174. The order confirmation screen is a screen for allowing the user to select whether a shipping process for shipping a new cartridge should be executed or not. When accepting selection of “YES” in the order confirmation screen from the user in T176, the terminal device 100 sends an order instruction to the shipping server 300 in T178.
When receiving the order instruction from the terminal device 100 in T178, the shipping server 300 determines that the shipping process should be executed and executes the shipping process in T180. The shipping server 300 firstly identifies the user information UI1 including the character string “UN” in the user table 338. Then, the shipping server 300 identifies the address information AD in the user information UI1 and executes a process for shipping a new cartridge 20b to the address indicated by the identified address information AD. As a result, the cartridge 20b is delivered to the user of the printer 10. A cartridge number CS2 is assigned to the cartridge 20b.
After this, when determining that the first predetermined time has elapsed since the consumable article information request was sent to the printer 10 in T140, the terminal device 100 sends the consumable article information request to the printer 10 in T190 of
After this, in T200, the cartridge 20a attached to the printer 10 is replaced with the cartridge 20b by the user of the printer 10. When the cartridge 20b is attached, the printer 10 updates the remaining amount information RQn in the memory 34 to “100”.
After this, when determining that the first predetermined time has elapsed since the consumable article information request was sent to the printer 10 in T190, the terminal device 100 sends the consumable article information request to the printer 10 in T210. T210 to T216 are similar to T140 to T146 in
(Case B;
Next, Case B will be described with reference to
Firstly, processes similar to T110 to T146 of
When determining that the first predetermined time has elapsed since the consumable article information request was sent to the printer 10 in T140, the terminal device 100 sends the consumable article information request to the printer 10 in T310. T310 to T316 are respectively similar to T140 to T146. When receiving the status confirmation from the terminal device 100 in T316 (S24 of
When receiving the second order notification from the shipping server 300 in T320, the terminal device 100 displays a second order notification screen on the display unit 114 in T322. The second order notification screen includes a message indicating that a new cartridge has not yet been ordered, a message prompting an order of a new cartridge, and the order URL “http://server.co.jp/UN” to be accessed to order a new cartridge. When accepting an operation for accessing the order URL “http://server.co.jp/UN” from the user in T326, the terminal device 100 sends to the shipping server 300 in T328 an access request including the order URL “http://server.co.jp/UN” as the destination URL. After this, processes similar to T170 to T180 of
(Effect of Present Embodiment)
Even though an e-mail including the first order notification is sent from the shipping server 300 to the terminal device 100, the user may not notice that the terminal device 100 received the e-mail, thus a new cartridge may not be ordered in response to the first order notification. Considerations may be given to a configuration in which an e-mail including the first order notification is sent to the terminal device 100 again if a new cartridge is not ordered in response to the first order notification after the previous e-mail including the first order notification has been sent to the terminal device 100, however, considering that the user did not notice the receipt of the previous e-mail including the first order notification, there is a high possibility that the user do not notice the receipt of the subsequent e-mail including the first order notification. In view of this, in the present embodiment, in the case of receiving the consumable article information including the remaining amount information from the terminal device 100 via the management server 200 (YES in S10 of
(Corresponding Relationships)
The management server 200 and the shipping server 300 are examples of “server”. The terminal device 100 is an example of “external device”. The remaining amount information is an example of “usage information”. The cartridges 20a an 20b are examples of “consumable article”. The first order notification, the second order notification, and the error notification are respectively examples of “first notification”, “second notification”, and “third notification”. The communication by e-mail and the communication between the shipping server 300 and the service application installed in the terminal device 100 are respectively examples of “first communication method” and “second communication method”. The order URL is an example of “URL to be accessed for ordering the new consumable article”. The cartridge number is an example of “identification information”. The consumable article information including the cartridge number is an example of “consumable article information includes predetermined information related to a vendor of the printer”.
S10 of
Next, a second embodiment will be described. In this embodiment, the process executed in S212 of
In the present embodiment, in S212, the CPU 332 determines whether a current remaining amount, which is the remaining amount indicated by the remaining amount information in the consumable article information received in S10 of
The CPU 332 sends the second order notification to the terminal device 100 in the case of determining that the current remaining amount is equal to or less than the previous remaining amount (YES in S212) and determining that the unshipped flag is “ON” (YES in S220). According to such a configuration, whether the cartridge attached to the printer 10 was replaced or not after the first order notification was sent can surely be determined. As such, sending of the second order notification to the terminal device 100 after the cartridge attached to the printer 10 was replaced by the user can be avoided.
(First Variant) The “server” may be a server in which the management server 200 and the shipping server 300 are configured integrally.
(Second Variant) The printer 10 may be an example of the “external device”. In this variant, the communication I/F 16 of the printer 10 may be connected to the Internet 8.
(Third Variant) The “consumable article” is not limited to the cartridge, but may be print paper. In this variant, the shipping server 300 receives consumable article information that includes information indicating the number of print paper used in printing from the terminal device 100.
