By performing the operation shown in
Next, the operation of each unit of the service providing system 1000 when the user P withdraws from the service will be described.
As shown in the flowchart FD, the application execution unit 501 transmits request-for-withdrawal information to the management server 2 (step SD1).
As shown in the flowchart FE, the server communication controller 201 receives the request-for-withdrawal information from the terminal device 5 (step SE1).
Next, the server communication controller 201 identifies the record R1 having the serial number 113 included in the request-for-withdrawal information received in step SE1 from the first management DB 212 (step SE2).
Next, the providing unit 202 determines whether the total amount of remaining ink indicated by the non-dedicated remaining amount data group of the record R1 identified in step SE2 is equal to or less than the total amount of remaining ink indicated by the group of dedicated remaining amount data of the record R1 (step SE3).
When the providing unit 202 determines that the total amount of remaining ink indicated by the non-dedicated remaining amount data group is equal to or less than the total amount of remaining ink indicated by the dedicated remaining amount data group (step SE3: YES), the server communication controller 201 transmits first withdrawal information to the multifunction machine 1 (step SE4).
The first withdrawal information is information indicating that the user P has withdrawn from the service, and includes the non-dedicated remaining amount data group of the record R1 identified in step SE2. Note that the first withdrawal information may include the dedicated remaining amount data group of the record R1 identified in step SE2.
In step SE4, the server communication controller 201 identifies, from the second management DB 213, the record R2 of the serial number 113 included in the request-for-withdrawal information received in step SE1. Then, the server communication controller 201 generates first withdrawal information to transmit the generated first withdrawal information to the multifunction machine 1 using the communication information about the record R2 identified from the second management DB 213.
Returning to the description of step SE3, when it is determined that the total amount of remaining ink indicated by the non-dedicated remaining amount data group is more than the total amount of remaining ink indicated by the dedicated remaining amount data group (step SE3: NO), the providing unit 202 delivers the new dedicated ink cartridge 121A to the user P (step SE5).
In step SE5, the providing unit 202 transmits the delivery request information to the delivery server 3. The delivery request information transmitted in step SE5 includes delivery destination information included in the record R1 identified in step SE2, information indicating delivery of the new dedicated ink cartridges 121A for all CMYK colors, and the like. When the delivery server 3 receives the delivery request information, the delivery server 3 instructs the delivery person to deliver the dedicated ink cartridges 121A for all colors to the delivery destination KO indicated by the delivery destination information in the received delivery request information.
When the providing unit 202 provides the new dedicated ink cartridge 121A, the server communication controller 201 transmits second withdrawal information to the multifunction machine 1 (step SE6).
The second withdrawal information is information indicating that the user P has withdrawn from the service, and includes the non-dedicated remaining amount data group of the record R1 identified in step SE2. Further, the second withdrawal information includes information indicating that the new dedicated ink cartridge 121A has been provided to the user P. Note that, as in the first withdrawal information, the second withdrawal information may include the dedicated remaining amount data group of the record R1 identified in step SE2.
As shown in the flowchart FF, the multifunction machine communication controller 101 receives either the first withdrawal information or the second withdrawal information (step SF1).
Next, the permission unit 102 performs a permission process based on the withdrawal information received in step SF1 (step SF2). The permission process is a process related to permission for printing using the dedicated ink cartridge 121A.
In step SG1, the permission unit 102 determines whether each of the non-dedicated remaining amount data included in the withdrawal information received in step SF1 indicates that the remaining amount of ink is zero. When all the non-dedicated remaining amount data indicates zero, the permission unit 102 makes an affirmative determination in step SG1. On the other hand, when there is non-dedicated remaining amount data that does not indicate zero among the plurality of pieces of non-dedicated remaining amount data, the permission unit 102 makes a negative determination in step SG1.
When it is determined that the amount of ink remaining in the non-dedicated ink cartridges 121B is zero for all colors (step SG1: YES), the permission unit 102 does not permit printing using the dedicated ink cartridge 121A (step SG2).
In step SG2, the permission unit 102 sets a setting value indicating non-permission for a permission/non-permission item in the setting data 112. The permission/non-permission item is an item for setting whether to permit printing using the dedicated ink cartridge 121A. When the dedicated ink cartridge 121A is installed, the print controller 103 does not perform printing when a setting value of non-permission is set for the permission/non-permission item.
When it is determined that the amount of ink remaining in the non-dedicated ink cartridges 121B for all colors is not zero, that is, there is a remaining amount of ink in any of the non-dedicated ink cartridges 121B (step SG1: NO), the permission unit 102 performs a process of step SG3. Here, the permission unit 102 determines whether the amount of ink remaining in the non-dedicated ink cartridges 121B when the user P subscribes to the service is equal to or less than the amount of ink remaining in the dedicated ink cartridges 121A installed when the user P withdraws from the service for all colors (step SG3).
In step SG3, the permission unit 102 reads the remaining amount of ink for all colors from the IC chip 121C of the dedicated ink cartridge 121A. Next, the permission unit 102 compares the remaining amount of ink indicated by the non-dedicated remaining amount data of the withdrawal information received in step SE1 with the read remaining amount of ink for each color. When the remaining amount of ink indicated by the non-dedicated remaining amount data is equal to or less than the read remaining amount of ink for all colors, the permission unit 102 makes an affirmative determination in step SG3. On the other hand, when the remaining ink amount indicated by the non-dedicated remaining amount data is greater than the read remaining amount of ink for at least one of the colors, the permission unit 102 makes a negative determination in step SG3.
When making the affirmative determination in step SG3, the permission unit 102 performs a first permission (step SG4).
The first permission indicates that printing using the dedicated ink cartridge 121A is permitted even after the user withdraws from the service. Further, for each of CMYK, the first permission indicates permission to use ink in the dedicated ink cartridge 121A for printing by the amount of ink remaining in a non-dedicated ink cartridge ICB at the time of subscribing to the service.
Specifically, in step SG4, permission unit 102 sets a setting value indicating permission for the permission/non-permission item in the setting data 112. Further, the permission unit 102 records the amount of ink in the dedicated ink cartridge 121A that is permitted to use for each of CMYK in the multifunction machine memory 110. Note that when the permission unit 102 permits printing, the print controller 103 subtracts the amount of ink consumed by printing from the amount of ink recorded in the multifunction machine memory 110 by the permission unit 102 each time printing is executed.
Example 1 shows an example of the first permission.
In Example 1, for each of CMYK, it is assumed that the amount of ink remaining in the non-dedicated ink cartridge 121B at the time of subscribing to the service is 5 g (grams). In Example 1, for each of CMYK, it is assumed that the amount of ink remaining in the dedicated ink cartridge 121A installed when the user withdraws from the service is 10 g. In this example, for each of CMYK, the permission unit 102 permits to use 5 g of ink in the dedicated ink cartridge 121A for printing as the first permission.
In Example 1, the permission unit 102 sets the setting data 112 to a setting value indicating permission for the permission/non-permission item, and records the information in the multifunction machine memory 110 that the amount of ink in the dedicated ink cartridge 121A that is permitted to use for each of CMYK is 5 g.
Returning to the description of step SG3, when the permission unit 102 makes a negative determination in step SG3, the permission unit 102 determines whether the withdrawal information received in step SF1 is the first withdrawal information or the second withdrawal information (step SG5).
When it is determined that the withdrawal information received in step SF1 is the first withdrawal information (step SG5: first withdrawal information), the permission unit 102 determines whether there is a second color whose amount can cover an addition amount (step SG6).
Here, the addition amount will be described. Prior to describing the addition amount, a first color, a second color, a first remaining amount, and a second remaining amount will be described. The first color is a color in which the remaining amount of ink indicated by the non-dedicated remaining amount data is greater than the amount of ink remaining in the dedicated ink cartridge 121A when the user P withdraws from the service. The second color is a color in which the remaining amount of ink indicated by the non-dedicated remaining amount data is less than the amount of ink remaining in the dedicated ink cartridge 121A when the user P withdraws from the service. The first remaining amount is a remaining amount of ink indicated by the non-dedicated remaining amount data corresponding to the first color when the user subscribes to the service. The second remaining amount is an amount of ink remaining in the dedicated ink cartridge 121A corresponding to the first color when the user withdraws from the service. The addition amount is an amount obtained by adding a difference between the first remaining amount and the second remaining amount to an amount of ink remaining in the non-dedicated ink cartridge 121B corresponding to the second color when the user subscribes to the service.
Example 2 shows an example of the addition amount, the first remaining amount, the second remaining amount, the first color, and the second color.
In Example 2, it is assumed that when the user subscribes to the service, the amount of ink remaining in the non-dedicated ink cartridge 121B for C (cyan) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for M (magenta) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for Y (yellow) is 5 g, and the amount of ink remaining in the non-dedicated ink cartridge 121B for K (black) is 10 g. In this example, when withdrawing from the service, the amount of ink remaining in the dedicated ink cartridge 121A for C (cyan) is 6 g, the amount of ink remaining in the dedicated ink cartridge 121A for M (magenta) is 5 g, the amount of ink remaining in the dedicated ink cartridge 121A for Y (yellow) is 5 g, and the amount of ink remaining in the dedicated ink cartridge 121A for K (black) is 9 g.
In Example 2, the first color is K (black) and the second color is C (cyan). Further, in Example 2, the first remaining amount is 10 g, and the second remaining amount is 9 g. Further, in Example 2, the addition amount is 6 g (=5 g+(10 g−9 g)).
Note that in the case of Example 2, C (cyan) is the second color whose amount can cover the addition amount, so that the permission unit 102 makes an affirmative determination in step SG6.
When it is determined that there is a second color whose amount can cover the addition amount (step SG6: YES), the permission unit 102 performs second permission (step SG7).
The second permission indicates that printing using the dedicated ink cartridge 121A is permitted even after the user withdraws from the service. In addition, for the first color, the second permission indicates permission to use ink in the dedicated ink cartridge 121A for printing by the amount of ink remaining in the dedicated ink cartridge 121A installed at the time of withdrawal from the service. Further, for one second color among the second colors whose amount can cover the addition amount, the second permission indicates permission to use ink in the dedicated ink cartridge 121A for printing by the addition amount. Further, for other colors, the second permission indicates permission to use ink in the dedicated ink cartridge 121A for printing by the amount of ink remaining in the dedicated ink cartridge 121A installed at the time of withdrawal from the service. Here, the other colors are colors other than the first color and the second color permitted to use by the addition amount.
Specifically, the permission unit 102 sets a setting value indicating permission for the permission/non-permission item in the setting data 112 in step SG7. Furthermore, the permission unit 102 records in the multifunction machine memory 110 the amount of ink in the dedicated ink cartridge 121A permitted to use for each of CMYK.
Example 3 shows an example of the second permission.
In Example 3, it is assumed that when the user subscribes to the service, the amount of ink remaining in the non-dedicated ink cartridge 121B for C (cyan) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for M (magenta) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for Y (yellow) is 5 g, and the amount of ink remaining in the non-dedicated ink cartridge 121B for K (black) is 10 g. In Example 3, it is assumed that when the user withdraws from the service, the amount of ink remaining in the dedicated ink cartridge 121A for C (cyan) is 6 g, the amount of ink remaining in the dedicated ink cartridge 121A for M (magenta) is 5 g, the amount of ink remaining in the dedicated ink cartridge 121A for Y (yellow) is 5 g, and the amount of ink remaining in the dedicated ink cartridge 121A for K (black) is 9 g. Further, in Example 3, K is the first color, and C (cyan) is the second color whose amount can cover the addition amount.
In example 3, for K (black), the permission unit 102 permits to use 9 g of ink in the dedicated ink cartridge 121A for printing as the second permission. Further, in Example 3, for C (cyan), the permission unit 102 permits to use 6 g (=5 g+(10 g−9 g)) of ink in the dedicated ink cartridge 121A for printing as the second permission. Further, in Example 3, for each of M (magenta) and Y (yellow), the permission unit 102 permits to use 5 g of ink in the dedicated ink cartridge 121A for printing as the second permission.
Note that when performing the second permission, in a case where there is a plurality of second colors whose amount can cover the addition amount, the permission unit 102 determines that the second color with the largest cumulative usage amount in the multifunction machine 1 is a second color that is permitted to use by the addition amount. The permission unit 102 acquires the cumulative usage amount of ink for all colors from a predetermined storage area, and determines that the second color with the largest acquired cumulative usage amount is a second color that is permitted to use by the addition amount. Note that the cumulative usage amount may be stored in the multifunction machine 1 or may be stored in a predetermined server device connected to the communication network NW.
Example 4 shows an example of the second permission.
In Example 4, it is assumed that when the user subscribes to the service, the amount of ink remaining in the non-dedicated ink cartridge 121B for C (cyan) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for M (magenta) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for Y (yellow) is 5 g, and the amount of ink remaining in the non-dedicated ink cartridge 121B for K (black) is 10 g. In Example 4, it is assumed that when the user withdraws from the service, the amount of ink remaining in the dedicated ink cartridge 121A for C (cyan) is 6 g, the amount of ink remaining in the dedicated ink cartridge 121A for M (magenta) is 6 g, the amount of ink remaining in the dedicated ink cartridge 121A for Y (yellow) is 5 g, and the amount of ink remaining in the dedicated ink cartridge 121A for K (black) is 9 g. Further, in Example 4, K is the first color, and C (cyan) and M (magenta) are the second colors whose amount can cover the addition amount.
In Example 4, when the cumulative usage amount of C (cyan) is larger than that of M (magenta), the permission unit 102 performs the second permission similar to Example 3.
On the other hand, in Example 4, when the cumulative usage amount of M (magenta) is larger than that of C (cyan), the permission unit 102 permits to use 9 g of ink in the dedicated ink cartridge 121A for printing for K (black) as the second permission. Furthermore, in this case, for M (magenta), the permission unit 102 permits to use 6 g (=5 g+(10 g−9 g)) of ink in the dedicated ink cartridge 121A for printing as the second permission. Further, in Example 3, for each of C (cyan) and Y (yellow), the permission unit 102 permits to use 5 g of ink in the dedicated ink cartridge 121A for printing as the second permission. Note that although an example in which the amount of ink is controlled in grams is described above, the unit of the amount of ink to be controlled is not limited to this.
Returning to the description of step SG6, when it is determined that there is no second color whose amount can cover the addition amount (step SG6: NO), the permission unit 102 performs third permission (step SG8).
The third permission indicates that printing using the dedicated ink cartridge 121A is permitted even after withdrawal from the service. Further, for the first color, the third permission indicates permission to use ink in the dedicated ink cartridge 121A for printing by the amount of ink remaining in the dedicated ink cartridge 121A installed at the time of withdrawal from the service. In addition, for a plurality of second colors among the second colors, the third permission indicates permission to use ink in the dedicated ink cartridge 121A for printing by the amount of ink obtained by considering a difference between the first remaining amount and the second remaining amount. In addition, for ink in other colors, the third permission indicates permission to use ink in the dedicated ink cartridge 121A for printing by the amount of ink remaining in the dedicated ink cartridge 121A installed at the time of withdrawal from the service. Here, the other colors are colors other than the first color and the second color obtained by considering a difference between the first remaining amount and the second remaining amount is considered.
Specifically, the permission unit 102 sets a setting value indicating permission for the permission/non-permission item in the setting data 112 in step SG8. Furthermore, the permission unit 102 records in the multifunction machine memory 110 the amount of ink in the dedicated ink cartridge 121A permitted to use for each of CMYK.
Example 5 shows an example of the third permission.
In example 5, it is assumed that when the user subscribes to the service, the amount of ink remaining in the non-dedicated ink cartridge 121B for C (cyan) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for M (magenta) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for Y (yellow) is 5 g, and the amount of ink remaining in the non-dedicated ink cartridge 121B for K (black) is 10 g. In Example 3, it is assumed that when the user withdraws from the service, the amount of ink remaining in the dedicated ink cartridge 121A for C (cyan) is 6 g, the amount of ink remaining in the dedicated ink cartridge 121A for M (magenta) is 6 g, and the amount of ink remaining in the dedicated ink cartridge 121A for Y (yellow) is 6 g, and the amount of ink remaining in the dedicated ink cartridge 121A for K (black) is 8 g. Further, in Example 5, K is the first color, and each of CMY is the second color whose amount cannot cover the addition amount.
In Example 5, for K (black), the permission unit 102 permits to use 8 g of ink in the dedicated ink cartridge 121A for printing as the third permission. Further, in Example 5, for two colors of CMY, the permission unit 102 permits to use 6 g (=(5 g+1 g)) of ink in the dedicated ink cartridge 121A for printing as the second permission. In Example 5, for one color of CMY, the permission unit 102 permits to use 5 g of ink in the dedicated ink cartridge 121A for printing as the second permission.
Returning to the description of step SG5, when it is determined that the withdrawal information received in step SF1 is the second withdrawal information (step SG5: second withdrawal information), the permission unit 102 performs fourth permission (step SG9).
The fourth permission indicates that printing using the dedicated ink cartridge 121A is permitted even after the user withdraws from the service. For the first color, the fourth permission indicates permission to use ink in the dedicated ink cartridge 121A for printing by the amount of ink remaining in the dedicated ink cartridge 121A installed at the time of withdrawal from the service. Further, for the first color, the fourth permission permits to use ink in the newly provided dedicated ink cartridge 121A for printing by a difference between the first remaining amount and the second remaining amount. For colors other than the first color, the fourth permission indicates permission to use ink in the dedicated ink cartridge 121A for printing by the amount of ink remaining in the dedicated ink cartridge 121A installed at the time of withdrawal from the service.
Specifically, the permission unit 102 sets a setting value indicating permission for the permission/non-permission item in the setting data 112 in step SG9. Furthermore, the permission unit 102 records in the multifunction machine memory 110 the amount of ink in the dedicated ink cartridge 121A permitted to use for each of CMYK.
Example 6 shows an example of the fourth permission.
In Example 6, it is assumed that when the user subscribes to the service, the amount of ink remaining in the non-dedicated ink cartridge 121B for C (cyan) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for M (magenta) is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for Y (yellow) is 5 g, and the amount of ink remaining in the non-dedicated ink cartridge 121B for K (black) is 10 g. In Example 6, it is assumed that when the user withdraws from the service, the amount of ink remaining in the dedicated ink cartridge 121A for C (cyan) is 5 g, the amount of ink remaining in the dedicated ink cartridge 121A for M (magenta) is 5 g, the amount of ink remaining in the dedicated ink cartridge 121A for Y (yellow) is 5 g, and the amount of ink remaining in the dedicated ink cartridge 121A for K (black) is 9 g. In Example 6, K (black) is the first color.
In example 6, for K (black), the permission unit 102 permits to use 9 g of ink in the dedicated ink cartridge 121A for printing as the fourth permission. In example 6, for K (black), the permission unit 102 permits to use 1 g of ink in the dedicated ink cartridge 121A to be newly delivered for printing as the fourth permission. In example 6, for each of CMY, the permission unit 102 permits to use 5 g of ink in the dedicated ink cartridge 121A for printing as the fourth permission.
Next, the operation of the multifunction machine 1 after the permission process will be described.
For each of CMYK, the permission unit 102 determines whether the amount of ink in the dedicated ink cartridge 121A permitted to use has been consumed in printing (step SH1). When the amount of ink recorded in the multifunction machine memory 110 is zero for any of CMYK, the permission unit 102 makes an affirmative determination in step SH1.
When it is determined that the amount of ink in the dedicated ink cartridge 121A has been consumed for printing (step SH1: YES), the permission unit 102 does not permit printing using the dedicated ink cartridge 121A (step SH2).
As described above, the service providing system 1000 provides a service of delivering the ink cartridge 121 containing ink used for the multifunction machine 1 to perform printing to the user P of the multifunction machine 1. The service providing system 1000 includes a providing unit 202 that delivers the dedicated ink cartridge 121A to be installed in place of the non-dedicated ink cartridge 121B installed in the multifunction machine 1 before the user subscribes to the service. The service providing system 1000 includes the server memory 210 that stores non-dedicated remaining amount data indicating the amount of ink remaining in the non-dedicated ink cartridge 121B. When the user withdraws from the service, the service providing system 1000 includes the permission unit 102 that permits the multifunction machine 1 to perform printing using the dedicated ink cartridge 121B according to the remaining amount of ink indicated by the non-dedicated remaining amount data stored in the server memory 210.
According to this, after the user withdraws from the service, printing by the multifunction machine 1 using the dedicated ink cartridge 121B is permitted according to the remaining amount of ink indicated by the non-dedicated remaining amount data stored in the server memory 210. Therefore, it is possible to perform printing by the amount of ink remaining in the ink cartridge 121 that was installed before the user subscribes to the service after the user withdraws from the service.
The ink cartridge 121 for each of a plurality of colors can be installed in the multifunction machine 1. The multifunction machine memory 110 stores non-dedicated remaining amount data of each of a plurality of colors. For the first color in which the remaining amount indicated by the non-dedicated remaining amount data is greater than the amount of ink remaining in the dedicated ink cartridge 121A when the user P withdraws from the service, the permission unit 102 permits to use the dedicated ink cartridge 121A for printing using the dedicated ink cartridge 121A by the amount of ink remaining in the dedicated ink cartridge 121A when the user P withdraws from the service. In addition, for the second color whose remaining amount indicated by the non-dedicated remaining amount data is less than the amount of ink remaining in the dedicated ink cartridge 121A when the user P withdraws from the service, the permission unit 102 permits to use the dedicated ink cartridge 121A by the addition amount for printing using the dedicated ink cartridge 121A. The addition amount is an amount obtained by adding a difference between the remaining amount indicated by the non-dedicated remaining amount data corresponding to the first color and the amount of ink remaining in the dedicated ink cartridge 121A corresponding to the first color when the user P withdraws from the service to the remaining amount indicated by the non-dedicated remaining amount data corresponding to the second color.
According to this, for the first color, when an amount of ink remaining in the ink cartridge 121 installed before the user subscribes to the service cannot be covered by a remaining amount of ink in the ink cartridge 121 installed at the time of withdrawal from the service, the amount by which the amount of ink remaining in the ink cartridge 121 installed before the user subscribes to the service cannot be covered by the amount of ink remaining in the ink cartridge 121 installed at the time of withdrawal from the service can be covered by the amount of ink in the dedicated ink cartridge 121A corresponding to the second color. Therefore, it is possible to appropriately perform printing for the amount of ink remaining in the ink cartridge 121 that was installed before the user subscribes to the service after the user withdraws from the service.
When there is a plurality of second colors, the permission unit 102 determines that the second color with the largest usage amount in the multifunction machine 1 is a second color that is permitted to use by the addition amount.
As a result, when an amount of ink remaining in the ink cartridge 121 installed before the user subscribes to the service cannot be covered by an amount of ink remaining in the ink cartridge 121 installed when the user withdraws from the service, the amount by which the remaining amount of ink in the ink cartridge 121 installed before the user subscribes to the service cannot be covered by the remaining amount of ink in the ink cartridge 121 installed when the user withdraws from the service can be covered by the amount of ink in the dedicated ink cartridge 121 of the color most used by the user P. Therefore, while taking into consideration the color most used by the user P, it is possible to perform printing for the amount of ink remaining in the ink cartridge 121 that was installed before the user subscribes to the service after the user withdraws from the service.
When the remaining amount of ink indicated by the non-dedicated remaining amount data is greater than the amount of ink remaining in the dedicated ink cartridge 121A when the user P withdrew from the service, the providing unit 202 delivers the new dedicated ink cartridge 121A. When the providing unit 202 provides the new dedicated ink cartridge 121A, the permission unit 102 permits the multifunction machine 1 to perform printing using the new dedicated ink cartridge 121A by the amount of ink corresponding to a difference between the remaining amount of ink indicated by the non-dedicated remaining amount data and the amount of ink remaining in the dedicated ink cartridge 121A when the user P withdraws from the service.
According to this, even when the amount of ink remaining in the ink cartridge 121 installed before the user subscribes to the service is greater than the amount of ink remaining in the ink cartridge 121 installed at the time of withdrawal from the service, it is possible to perform printing using the dedicated ink cartridge 121A by the amount of ink remaining in the non-dedicated ink cartridge 121B installed when the user subscribes to the service. Therefore, printing for the amount of ink remaining in the ink cartridge 121 that was installed before the user subscribes to the service can be reliably performed after the user withdraws from the service.
The method of controlling the service providing system 1000 includes delivering the dedicated ink cartridge 121A, storing the non-dedicated remaining amount data indicating the amount of ink remaining in the non-dedicated ink cartridge 121B, and permitting the multifunction machine 1 to perform printing using the dedicated ink cartridge 121A according to the remaining amount of ink indicated by the non-dedicated remaining amount data stored when the user P withdraws from the service.
According to this, the effects same as those of the service providing system 1000 described above can be obtained.
Next, the second embodiment will be described. The second embodiment differs from the first embodiment in the method of determining the second color that is permitted to use by the addition amount. The permission unit 102 of the second embodiment determines the second color that can most reduce the imbalance in the remaining amount of ink between the second colors is a second color that is permitted to use by the addition amount.
For example, it is assumed that when the user subscribes to the service, the amount of ink remaining in the non-dedicated ink cartridge 121B for C is 6 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for M is 5 g, the amount of ink remaining in the non-dedicated ink cartridge 121B for Y is 6 g, and the amount of ink remaining in the non-dedicated ink cartridge 121B for K is 10 g. In this example, it is assumed that when the user withdraws from the service, the amount of ink remaining in the dedicated ink cartridge 121A for C is 6 g, the amount of ink remaining in the dedicated ink cartridge 121A for M is 7 g, the amount of ink remaining in the dedicated ink cartridge 121A for Y is 8 g, and the amount of ink remaining in the dedicated ink cartridge 121A for K is 9 g. In this example, K corresponds to the first color, and each of C, M, and Y corresponds to the second color. In this example, the first remaining amount is 10 g and the second remaining amount is 9 g. In this example, the color that is configured to most reduce the imbalance in the remaining amount of ink between C, M, and Y is M that has the least remaining amount of ink. Therefore, in this example, for M among the second colors C, M, and Y, the permission unit 102 permits to use 6 g of ink in the dedicated ink cartridge 121A for printing. As a result, 6 g, 6 g, 6 g, and 9 g of ink for C, M, Y, and K, respectively, are permitted to use when the user withdraws from the service, and the imbalance in the remaining amount of ink between CMY is reduced compared to when the user subscribes the service.
As described above, when there is a plurality of second colors, the permission unit 102 determines that the second color that is configured to most reduce the imbalance in the remaining amount between the second colors is a second color that is permitted to use by the addition amount.
According to this, when an amount of ink remaining in the ink cartridge 121 installed before the user subscribes to the service cannot be covered by an amount of ink remaining in the ink cartridge 121 installed at the time of withdrawal from the service, the amount by which the remaining amount of ink in the ink cartridge 121 installed before the user subscribes to the service cannot be covered by the remaining amount of ink in the ink cartridge 121 installed at the time of withdrawal from the service is covered by the amount of ink in the dedicated ink cartridge 121A of the color that is configured to most reduce the imbalance in the remaining amount of ink between the second colors. Therefore, while efficiently consuming ink, it is possible to perform printing for the amount of ink remaining in the ink cartridge 121 that was installed before the user subscribes to the service after the user withdraws from the service.
The third embodiment is different from the first embodiment and the second embodiment in that the multifunction machine memory 110 stores the non-dedicated remaining amount data of each of CMYK. In the third embodiment, when the non-dedicated ink cartridge 121B is installed in the multifunction machine 1, the print controller 103 updates the remaining amount of ink recorded on the IC chip 121C of the non-dedicated ink cartridge 121B every time the printing unit 12 performs printing. Furthermore, in the third embodiment, when the non-dedicated ink cartridge 121B is installed in the multifunction machine 1, the print controller 103 updates the remaining amount of ink indicated by the non-dedicated remaining amount data stored in the multifunction machine memory 110. In the third embodiment, the multifunction machine memory 110 corresponds to an example of a “storage unit”.
In the third embodiment, since the non-dedicated remaining amount data is stored in the multifunction machine memory 110, the non-dedicated remaining amount data is not stored in the server memory 210. Therefore, the withdrawal information transmitted by the management server 2 does not include the non-dedicated remaining amount data group. When the withdrawal information is transmitted from the management server 2, the permission unit 102 of the third embodiment reads the non-dedicated remaining amount data stored in the multifunction machine memory 110 and executes the operation of
As described above, the multifunction machine 1 that performs printing using the ink cartridge 121 includes the multifunction machine memory 110 that stores non-dedicated remaining amount data indicating the amount of ink remaining in the non-dedicated ink cartridge 121B that was installed in the multifunction machine 1 before the user subscribes the service, and the permission unit 102 that permits printing using the dedicated ink cartridge 121A according to the remaining amount of ink indicated by the non-dedicated remaining amount data stored in the multifunction machine memory 110 when the user P withdraws from the service.
According to this, the effects same as those of the service providing system 1000 of the first embodiment are achieved.
Each of the above-described embodiments shows only an aspect of the present disclosure, and any modification and application can be made within the scope of the present disclosure.
In each of the above-described embodiments, the multifunction machine 1 includes a serial type ink jet head, but the ink jet head included in the multifunction machine 1 is not limited to a serial type.
In each of the embodiments described above, the multifunction machine 1 is illustrated as an example of a printing apparatus, but the printing apparatus is not limited to the multifunction machine 1. The printing apparatus may be a device that does not have a scanning function, or a device that has another function such as a facsimile function.
In each of the embodiments described above, the ink jet method is exemplified as the printing method of the multifunction machine 1, but the printing method of the multifunction machine 1 is not limited to the ink jet method, and may be another printing method such as an electrophotographic method. Note that when the printing method of the multifunction machine 1 is an electrophotographic method, the toner cartridge installed in the multifunction machine 1 corresponds to an example of a “container”, and the toner contained in the toner cartridge corresponds to an example of “printing material”.
In each of the embodiments described above, the permission unit 102 is described as a functional unit of the multifunction machine processor 100. However, server processor 200 may function as the permission unit 102. In this configuration, the management server 2 transmits the content permitted by the permission unit 102 to the multifunction machine 1, and the multifunction machine 1 performs printing using the dedicated ink cartridge 121A within the range of the permitted content. In this embodiment, the management server 2 includes the providing unit 202 that delivers the dedicated ink cartridge 121A and the permission unit 102 that acquires the non-dedicated remaining amount data from the server memory 210 that stores the non-dedicated remaining amount data when the user withdraws from the service and permits the multifunction machine 1 to perform printing using the dedicated ink cartridge 121 according to the remaining amount of ink indicated by the non-dedicated remaining amount data. According to this, the effects same as those of the service providing system 1000 of the first embodiment are achieved.
The functions of the multifunction machine processor 100, the server processor 200, and the terminal processor 500 may be implemented by processors or a plurality of semiconductor chips.
