Further, w % ben the service user performs an input operation on the terminal device 2, the terminal device 2 creates an account for using the printing service and logs in to the service website as shown in a processing P2. The account is created by registering at least one of a name, an mail address, or a password of the service user.
Next, when the service user performs an input operation on the terminal device 2, the terminal device 2 registers the printer 3 in the service website as shown in a processing P3. Specifically, the terminal device 2 transmits printer identification information for specifying the printer 3 to the service server 4.
When the service server 4 receives the printer identification information, the service server 4 communicates with the printer 3 via the WAN 6 and detects the printer 3 according to the printer identification information, as shown in a processing P4.
When the service server 4 detects the printer 3, the service server 4 registers the printer 3 as a registered printer for the account of the service user, and transmits a registration success notification indicating that the registration is successful to the terminal device 2 as shown in a processing P5.
Next, when the service user performs an input operation on the terminal device 2, the terminal device 2 transmits, to the service server 4, a service start request for applying for a printing service of the registered printer, as shown in a processing P6. The service start request includes plan information indicating a type of a plan of the applied printing service, delivery destination information indicating a delivery destination of a cartridge, and payment information (for example, a credit card number) for charging a usage fee for the printing service.
When the service server 4 receives the service start request, the service server 4 executes periodic information notification setting to cause the printer 3 to transmit notification information periodically (for example, every 12 hours), as shown in a processing P7. The notification information includes firmware identification information, page count information, consumable item remaining amount information, replacement count information, and cartridge type information.

(4) Effects
In the above configuration, the management system 1 configured such that the printer 3 and the service server 4 are communicable with each other and the service server 4 includes the controller 51. The management program 62a having the above configurations is configured to cause the controller 51 to execute a first reception processing, a second reception processing, a cartridge determination processing, a first shipping processing, a shipping determination processing, and a second shipping processing. The first, second, third, and fourth cartridges 37a, 37b, 37c, and 37d that contain cyan, magenta, yellow, and black color materials are mounted in the printer 3.
In the first reception processing, the service server 4 receives the service start request for requesting the printer 3 to start a printing service including a shipping service for shipping the first to fourth cartridges 37a to 37d from the terminal device 2. In the second reception processing, the service server 4 receives the cartridge type information indicating a type of each of the first to fourth cartridges 37a to 37d mounted in the printer 3 and the consumable item remaining amount information indicating a remaining amount of a color material in each of the first to fourth cartridges 37a to 37d from the printer 3.
In the cartridge determination processing, when the service start request is received, it is determined whether the first to fourth cartridges 37a to 37d mounted in the printer 3 are service available cartridges based on the received cartridge type information.
In the first shipping processing, when it is determined that the first to fourth cartridges 37a to 37d mounted in the printer 3 are not service available cartridges, the first to fourth cartridge shipping instructions of the first to fourth service dedicated cartridges are transmitted to the shipping server 5. As a result, a cartridge shipment of each of the first to fourth cartridge shipping instructions is performed. The first shipping processing includes a preparation processing, an ordering processing, and the like for the shipping.
In the shipping determination processing, when it is determined that the first to fourth cartridges 37a to 37d mounted in the printer 3 are the service available cartridges, it is determined whether the first to fourth remaining amount shortage conditions set in advance are satisfied based on the received consumable item remaining amount information.
In the second shipping processing, when it is determined that the first to fourth remaining amount shortage conditions are satisfied, the first to fourth cartridge shipping instructions of the first to fourth service dedicated cartridges are transmitted to the shipping server 5. As a result, a cartridge shipment corresponding to each of the first to fourth cartridge shipping instructions is performed. The second shipping processing includes a preparation processing, an ordering processing, and the like for the shipping.
Accordingly, in a case where the first to fourth cartridges 37a to 37d mounted in the printer 3 are service available cartridges, the shipping of the first to fourth service available cartridges is avoidable until the first to fourth cartridges 37a to 37d mounted in the printer 3 need to be replaced. Therefore, the occurrence of a situation in which a user of the printer 3 has an extra cartridge.
Further, even when the first to fourth cartridges 37a to 37d mounted in the printer 3 are service available cartridges, it is possible to ship the first to fourth service dedicated cartridges to a user of the printer 3 when the remaining amounts of color materials of the first to fourth cartridges 37a to 37d are small. Accordingly, the management program 62a is configured to cause the service server 4 to determine whether to ship a service available cartridge. Therefore, the management program 62a does not need a shipping determination by a user of the printer 3, and convenience for the user of the printer 3 is improved.
A commercially available cartridge that is purchasable in a store, a packaged cartridge that is packaged with the printer 3, and a service dedicated cartridge dedicated to a printing service are mountable in the printer 3. The service available cartridge includes the packaged cartridge and the service dedicated cartridge. Since the packaged cartridge is the service available cartridge, a user of the printer 3 may use the printer 3 in a state in which a printing service is started without waiting for the arrival of the service dedicated cartridge.
The management program 62a is configured to cause the controller 51 to further execute a first charging start processing. In the first charging start processing, when it is determined that all of the first to fourth cartridges 37a to 37d mounted in the printer 3 are service available cartridges, a charging service for charging a fee for the printing of the printer 3 is started. Accordingly, the management program 62a may start the charging service at an appropriate timing for the usage of the printer 3 by using the service available cartridges of all colors.
The management program 62a is configured to cause the controller 51 to execute a second charging start processing. In the second charging start processing, when it is determined that a part of the first to fourth cartridges 37a to 37d mounted in the printer 3 is a service available cartridge, a charging service for charging a fee for the printing of the printer 3 is started. Accordingly, the management program 62a may start the charging service at an appropriate timing for the usage of the printer 3 by using the service available cartridges of some colors.
The management program 62a is configured to cause the controller 51 to execute an all-cartridge shipment processing. The all-cartridge shipment processing is a processing of transmitting, to the shipping server 5, an all-cartridge shipping instruction of the first to fourth service dedicated cartridges, when it is determined that all of the first to fourth cartridges 37a to 37d mounted in the printer 3 are not the service available cartridges. Accordingly, since the management program 62a instructs the shipping of the service available cartridges of all colors together, the efficiency of a shipping operation is improved.
The present disclosure is not limited to the embodiment described above and may be implemented in various modifications.
For example, the service server 4 is a single physical server in the embodiment. Alternatively, the service server 4 may include a plurality of physical servers. The service server 4 may be configured by at least one of a plurality of virtual servers constructed by dividing one physical server by virtualization software.
In the embodiment described above, the first to fourth remaining amount shortage conditions are a condition in which a remaining amount of the color material in each of the first to fourth cartridges 37a to 37d is equal to or less than the first to fourth shortage threshold. Alternatively, the time until the remaining amount of the color material becomes 0 may be determined based on a decreasing tendency of the remaining amount of the color material of each of the first to fourth cartridges 37a to 37d, and when this time is short, it may be determined that the first to fourth remaining amount shortage conditions are satisfied.
The printer according to the present disclosure is the printer 3 in the embodiment described above. Alternatively, the printer according to the present disclosure includes a multifunction device, a copier, and a facsimile that have a scanner function of reading an image from a document. The printer is not limited to an inkjet printer, and may be a laser printer or an LED printer. The LED printer refers to a printer in which a unit for exposing a photosensitive member is an LED head. In this case, a color material is a toner.
A plurality of functions of one constituent element in the embodiment described above may be implemented by a plurality of constituent elements, or one function of one constituent element may be implemented by a plurality of constituent elements. A plurality of functions of a plurality of constituent elements may be implemented by one constituent element, or one function to be implemented by a plurality of constituent elements may be implemented by one constituent element. A part of the configurations in the embodiment described above may be omitted. At least a part of the configurations in the embodiment described above may be added to or replaced with configurations of another embodiment.
