Description

[Technical field]

[0001] The present invention relates to a printing apparatus, a print processing system, and a print processing method that form an image on a print medium using consumables. [Background technology]

[0002] 2. Description of the Related Art Conventionally, as described in, for example, Japanese Patent Laid-Open No. 2003-233999, there is known a technique in which a predetermined contract is concluded with a user of a printing device, and based on the contract, a fee is charged to the user according to the content of printing. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP2018-118406A Summary of the Invention [Problem to be solved by the invention]

[0004] When a contract is concluded as described above, the consumables used in the printing device, such as cartridges, are different from commercially available consumables and are specific to the contract (hereinafter referred to as "contracted consumables") For this reason, it is conceivable that the printing device will identify the type of consumables installed, and if commercially available consumables are installed instead of contracted consumables after the contract is concluded, a warning message or the like will be displayed to that effect.

[0005] After the contract is concluded, the contract consumables are usually delivered to the user from a specified delivery source, but depending on the user's circumstances, there may be cases where the user wants to print before the delivery arrives. In such cases, the only option is to use commercially available consumables, so it is not appropriate to always display a warning when installing commercially available consumables, as described above. Also, in the case where contracted consumables are delivered and arrive while commercially available consumables are being used out of necessity as described above, it is more beneficial for the user in terms of cost, for example, to replace the commercially available consumables with the contracted consumables rather than the commercially available consumables. However, some users may wish to use up the commercially available consumables currently installed due to the effort required for replacement or other reasons, so it is preferable to display a message asking the user's preference.

[0006] As described above, when a contract is concluded with a user, it is more convenient for the user if the printing device displays appropriate information according to the type of consumables installed and the delivery status of the contracted consumables. However, the above-mentioned prior art does not take such a point into consideration.

[0007] An object of the present invention is to provide a printing device, a print processing system, and a printing program that can provide appropriate information to a user depending on the type of consumable installed and the delivery status of the consumable after a contract is concluded. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the present invention provides a printing device comprising an installation unit into which consumables used for printing are installed, a printing unit that prints an image on a print medium using the consumables, a display unit that displays information about the consumables, and a control unit, and which is operable based on the contents of a contract concluded with a contracting party regarding the consumables used for the printing, wherein the control unit executes a first acquisition process that acquires arrival time information of a first consumable delivered to the printing device based on the contract contents, a first determination process that determines the type of the consumable installed in the installation unit, and a first display process that displays consumable handling related information on the display unit depending on the arrival time information acquired in the first acquisition process and the determination result of the first determination process.

[0009] The printing device of the present invention has an attachment unit, a printing unit, a display unit, and a control unit, and is operable based on the content of a contract concluded with a contracting party regarding consumables used for printing in the printing unit. The control unit executes a first acquisition process, a first determination process, and a first display process. In the first acquisition process, arrival time information of a first consumable that corresponds to the content of the contract and is delivered to the printing device is acquired. In the first determination process, the type of the consumable attached to the attachment unit is determined. The acquired information on the arrival time of the contracted consumable and information on handling of the consumable according to the result of the judgment are displayed on the display unit in the first display process. According to the present invention, by displaying on the display unit the arrival time information corresponding to the delivery status of the first consumable after the contract is concluded and the result of the judgment related to the type of the installed consumable, appropriate information can be provided to the user. Effect of the Invention

[0010] According to the present invention, it is possible to provide the user with appropriate information according to the type of the installed consumable product and the delivery status of the consumable product after the contract is concluded. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

[0013] A print processing system according to an embodiment of the present invention is shown in Fig. 1. This embodiment is an embodiment of a print processing system 1 that can provide a delivery service based on a delivery contract in which replacement consumables are automatically delivered when consumables used in a multifunction device 200 have been consumed to a certain extent. The print processing system 1 can also provide a print service based on a printing contract in which a fee is charged according to the number of prints made by the multifunction device 200.

[0014] <Outline of the printing processing system> 1, the print processing system 1 includes an information management server 100, a multifunction device 200, a mobile terminal 300, and a delivery management server 400. The information management server 100, the multifunction device 200, the mobile terminal 300, and the delivery management server 400 are connected to a network NT and can communicate with each other. The multifunction device 200 is an example of a printing device, and the information management server 100 and the mobile terminal 300 are examples of external devices.

[0015] <Information management server> The information management server 100 is a server installed and managed by, for example, a manufacturer of the multifunction device 200, and includes a processor 110, a storage device 115, and an interface 190. The processor 110, the storage device 115, and the interface 190 are connected to each other via a bus 105.

[0016] The memory device 115 includes a volatile memory device 120 and a non-volatile memory device 130 . The volatile storage device 120 is, for example, a DRAM, and has a user ID storage area 121. The non-volatile storage device 130 is, for example, a hard disk drive or a solid state drive, and has a program storage area 131 and a fee table storage area 132. The fee table storage area 132 stores, for example, predetermined correlations for calculating fees charged to a user in response to printing or delivery of ink cartridges.

[0017] The processor 110 is a device for performing data processing, such as a CPU. The processor 110 executes a program stored in the program storage area 131 to perform various processes shown in Figs. 2, 3, 4, 6, 7, etc., which will be described later, including data communication with the mobile terminal 300, the multifunction device 200, and the delivery management server 400 connected to the network NT.

[0018] The interface 190 is a wired LAN interface or a wireless interface for communicating with other devices, and is connected to a network NT.

[0019] <Delivery management server> The delivery management server 400 is installed in, for example, a delivery service company that provides delivery services for various items, and has a processor, a storage device, and an interface for connecting to the network NT (not shown).

[0020] <Multifunction device> The multifunction device 200 is owned by, for example, a business entity that provides the printing service. The multifunction device 200 may be owned by a user who uses the multifunction device. The multifunction device 200 includes a scanner unit 280, a printing unit 290, a processor 210, a storage device 215, a display unit 240, an operation unit 250, a timer circuit 260, a communication unit 285, a communication interface 270, and a cover sensor 275. The scanner unit 280, the printing unit 290, the processor 210, the storage device 215, the display unit 240, the operation unit 250, the timer circuit 260, the communication unit 285, the cover sensor 275, and the communication interface 270 are connected to each other via a bus 205.

[0021] The storage device 215 includes a volatile storage device 220 and a non-volatile storage device 230. The volatile storage device 220 is, for example, a DRAM. The non-volatile storage device 230 is, for example, a flash memory. The non-volatile storage device 230 includes a consumables-related information storage area 231 that stores consumables-related information related to the ink cartridge 50, a program storage area 232, a contract information storage area 233 that stores the contents of the contract concluded between the user and the contracting party, and an arrival time information storage area 234 that stores arrival time information indicating the expected arrival date and time of arrival of the contract cartridge 50 after delivery or the arrival completion date and time of arrival. The arrival time information storage area 234 is an example of a storage unit. Various programs are stored in the program storage area 232, and the various programs include operation programs of the multifunction device, including the print processing program of this embodiment related to the execution of the print processing method of this embodiment based on the sequence flows and flowcharts of Figures 2, 3, 4, 6, and 7, which will be described later. This print processing program is, for example, stored in advance as firmware in the program storage area 232. Information regarding print operations based on the contract details, which will be described later, is also stored as part of the print processing program.

[0022] The processor 210 is a device that performs data processing, and is, for example, a CPU. The processor 210 is an example of a control unit. The processor 210 executes the print processing program stored in the program storage area 232, and executes the print processing method by the print processing system 1 of this embodiment in cooperation with the processor 110. The processor 210 functionally includes a first display processing unit 210A, a second display processing unit 210B, and a delivery confirmation processing unit 210C, the details of which will be described later.

[0023] The display unit 240 is, for example, a liquid crystal display, and is capable of displaying various information related to consumables as described below. The operation unit 250 is a device that accepts operations by a user. The user can input various instructions to the multifunction device 200 by operating the operation unit 250. The communication interface 270 is a wired or wireless network interface for communicating with other devices, and is connected to the network NT.

[0024] Scanner unit 280 optically reads an original, which is an object to be read, using a photoelectric conversion element such as a CCD or a CMOS, and generates scan data representing the read image.

[0025] The printing unit 290 prints an image on the transported paper in a predetermined manner while taking out the paper from the paper feed tray and transporting it by a transport mechanism (not shown). The following description will be given taking an example of printing by the inkjet method. The printing unit 290 forms an image on the paper using ink in the ink cartridge 50 detachably mounted in the cartridge holder 51 in accordance with a print job sent from the mobile terminal 300 or a print job generated by the printing unit 290 itself based on an operation on the operation unit 250. Note that the paper is an example of a print medium, the ink cartridge 50 is an example of a consumable item, and the cartridge holder 51 is an example of a mounting unit. Note that in detail, the ink cartridges 50 include cyan ink, magenta ink, yellow ink, and black ink, but for convenience, they will not be distinguished from each other and will be simply referred to as "ink cartridge 50" unless otherwise specified.

[0026] The communication unit 285 is, for example, a terminal, and is electrically connected to a cartridge memory (IC chip) of the ink cartridge 50 mounted in the cartridge holder 51. That is, as described above, the multifunction device 200 of this embodiment is a model that can be used in a delivery service based on a specific delivery contract, and is also a model that can be used in a print service based on a separate specific print contract. The ink cartridge 50 used based on such a contract (hereinafter, simply referred to as a "contract cartridge 50") has specifications different from those of a normal ink cartridge 50 (hereinafter, simply referred to as a "normal cartridge 50") that is purchased commercially by the owner of the multifunction device 200. The contract cartridge 50 is an example of a first consumable, and the normal cartridge 50 is an example of a second consumable. Note that a counterfeit ink cartridge 50 that is a counterfeit product that illegally imitates the normal cartridge 50 is also an example of a second consumable.

[0027] Each ink cartridge 50 is provided with a cartridge memory (not shown), and cartridge information is stored in this cartridge memory. This cartridge information includes cartridge type information indicating whether the ink cartridge 50 is a contract cartridge 50 or a normal cartridge 50. The processor 210 acquires the above cartridge information from the cartridge memory of each ink cartridge 50 connected by the communication unit 285. As a result, the processor 210 can identify whether the ink cartridge 50 mounted in the cartridge holder 51 is a contract cartridge 50 or a normal cartridge 50 based on the acquired information. The cartridge holder 51 is provided with an openable / closable cover (not shown), which is opened when the ink cartridge 50 is mounted on or removed from the cartridge holder 51, and closed after mounting or removal. The open and closed states of this openable / closable cover are detected by the cover sensor 275 using a known method, and a corresponding detection signal is input to the processor 210.

[0028] At this time, in the multifunction device 200, the remaining ink amount or the amount of ink used in the ink cartridge 50 attached to the cartridge holder 51 is obtained by a known method through processing by the processor 210. Then, when the remaining ink amount decreases and reaches a predetermined remaining amount threshold, or when the amount of ink used increases and reaches a predetermined usage amount threshold, it is possible to display on the display unit 240 that the ink cartridge 50 should be replaced. This makes it convenient for the user to replace the ink cartridge 50. Note that the remaining ink amount and the amount of ink used will hereinafter be collectively referred to as the "usable amount" as appropriate.

[0029] The clock circuit 260 is, for example, a circuit such as an RTC (Real Time Clock) and has a function as an internal clock that keeps time. The clock circuit 260 is driven by the supply of driving power from a power supply circuit (not shown), and the current time information kept by the clock circuit 260 can be referenced by the processor 210 at any time. The processor 210 may obtain the current time information from an SNTP (Simple Network Time Protocol) server (not shown) on the network NT via the communication interface 270, instead of from the clock circuit 260. Alternatively, the current time information kept by the clock circuit 260 may be calibrated as appropriate based on time information from the SNTP server or time information acquired from the mobile terminal 300. In particular, when the power supply circuit is not supplying driving power because the power supply of the multifunction peripheral 200 is turned off, the current time information in the clock circuit 260 may be calibrated as needed based on time information from the SNTP server, etc. Furthermore, in such a case, the time information from the SNTP server or information management server 100 may be forcibly injected into the clock circuit 260 and used as the current time information.

[0030] <Mobile devices> The mobile terminal 300 is a mobile terminal such as a smartphone owned by a user, and is connected to the network NT via wireless communication. The mobile terminal 300 has a processor, a storage device, an interface for connecting to the network NT, and an appropriate display device (not shown). Various programs are stored in a program storage area provided in the storage device, and these various programs include a processing program related to the execution of the sequence flow in FIG. 2 described below. Note that instead of the mobile terminal 300, other information terminals such as personal computers and tablet computers may be used. Hereinafter, these information terminals will be collectively referred to simply as "information terminals 300" as appropriate.

[0031] <Features of the embodiment> In the above configuration, a feature of this embodiment is that consumable handling information (details will be described later) is displayed on the display unit 240 depending on the delivery status of the ink cartridge 50 after the aforementioned delivery contract has been concluded and the type of ink cartridge 50 attached to the cartridge holder 51.

[0032] That is, after the delivery contract is concluded, the contract cartridge 50 is delivered from a specified delivery source to the user under the management of the delivery management server 400. However, depending on the user's circumstances, there may be cases where the user wishes to print before the delivery arrives. In such cases, the only option is to use a commercially available normal cartridge 50, so it is necessary to allow the normal cartridge 50 to be installed in the cartridge holder 51 even after the delivery contract is concluded, and a warning display or the like should not be displayed. Also, as described above, if the contract cartridge 50 is delivered and arrives or is expected to arrive while the normal cartridge 50 is being used due to unavoidable circumstances, it is more beneficial for the user in terms of cost burden to display that fact and stop using the normal cartridge 50 and replace it after the contract cartridge 50 arrives. Alternatively, some users may wish to use up the normal cartridge 50 currently installed even when the contract cartridge 50 arrives, due to the effort required for replacing the normal cartridge 50 or other reasons. In such cases, it is preferable to display a message asking the user's intention.

[0033] <Processing flow> The processes executed in this embodiment in response to the above will be explained below in order with reference to FIGS.

[0034] <At the time of contract conclusion> First, the process for concluding a delivery contract, which is executed by the processor 210 of the multifunction device 200, the processor 110 of the information management server 100, the processor of the delivery management server 400, and the processor of the information terminal 300, will be explained using the sequence flow in Fig. 2. In the following explanation, the description of each processor will be omitted, and phrases such as "in the processor of the multifunction device 200" and "by the processor of the multifunction device 200" will simply be described as "in the multifunction device 200" and "by the multifunction device 200".

[0035] 2, first, in the multifunction device 200, the user performs an appropriate operation via the operation unit 250, and the model number of the normal cartridge 50 compatible with the multifunction device 200 is displayed on the display unit 240 based on the stored contents of the consumables related information storage area 231 described above (S1). At this point, a printing contract, which will be described later, has not been concluded, and either a normal cartridge 50 is attached to the cartridge holder 51, or no cartridge 50 is attached to the cartridge holder 51.

[0036] In addition, in the information terminal 300, when the user performs an appropriate operation via the operation unit 250, the model numbers (not shown) of the black ink, cyan ink, magenta ink, and yellow ink obtained from the multifunction device 200 as described above are displayed in conjunction with the processing of S1 (S3).

[0037] Thereafter, when the user performs appropriate operations on the information terminal 300 with the intention of using the multifunction device 200 based on the above-mentioned delivery contract and printing contract, a delivery contract and printing contract request is sent from the information terminal 300 to the information management server 100 and is received by the information management server 100 (S5).

[0038] In response to this, the information management server 100 makes certain preparations for executing the printing service based on the printing contract, such as preparations for counting the number of printed pages.

[0039] Thereafter, contract start information, i.e., an activation instruction, is transmitted from the information management server 100 and is received by the multifunction device 200 (S9). As a result, both the delivery contract and the printing contract described above are established. Upon receiving the activation instruction, the multifunction device 200 writes, by flagging or otherwise processing, in the contract information storage area 233 that the multifunction device 200 itself has transitioned to a contract start state. By performing activation, the multifunction device 200 is able to perform printing operations based on the details of the concluded contracts.

[0040] At this time, information such as the flag stored in the contract information storage area 233 is an example of information corresponding to the "contract conclusion content" in the present invention, and the printing operation of the multifunction device based on the presence or absence of the flag is an example of an "operation based on the contract conclusion content". As this "operation based on the contract conclusion content", the processor 210 of the multifunction device 200 can perform processing such as accessing consumable related information including consumable handling related information described below, stored in the consumable related information storage area 231 of the storage device 215, depending on the presence or absence of the flag, and displaying it on the display unit 240. As another aspect, the information corresponding to the "contract conclusion content" may be stored in the consumable related information storage area 231 as the contract conclusion content itself.

[0041] Thereafter, in the multifunction device 200, in response to the establishment of the printing contract, under the control of the processor 210, the display of the model number of the regular cartridge 50 that started in S1 is stopped. In other words, it is no longer displayed (S10). Then, based on the contents stored in the aforementioned consumables related information storage area 231, the model number of the contract cartridge 50 that is compatible with the multifunction device 200 is newly displayed on the display unit 240 (S11).

[0042] Also, in the information terminal 300, in response to the establishment of the contract and in coordination with the processing of S11, the display of the model number of the normal cartridge 50 that began in S3 is stopped. In other words, it is no longer displayed (S12). Then, as in the above, the model number of the contract cartridge 50 that is compatible with the multifunction device 200 is newly displayed (S13).

[0043] Thereafter, the multifunction device 200 transmits a contract approval notice, i.e., an activation notice (S15), which is received by the information management server 100 (S17). Note that the information management server 100 may make an inquiry, and the multifunction device 200 may transmit an activation notice in response to the inquiry. This allows the information management server 100 to recognize that the above-mentioned printing contract has been concluded. Thereafter, the multifunction device 200 periodically communicates with the information management server 100 to exchange information about the contract.

[0044] Thereafter, the delivery registration information for delivering the contract cartridge 50 to the user is transmitted from the information management server 100 to the delivery management server 400 (S19). This completes the registration arrangements for the delivery of the contract cartridge 50 from the delivery service company to the user.

[0045] <Processing when the MFP is turned on or when a print job is completed - Part 1> As an example of a case in which consumable handling information is displayed, an example of processing performed by the first display processing unit 210A of the processor 210 when the multifunction device 200 is turned on or when execution of a print job by the printing unit 290 is completed is described using the flow in Figure 3.

[0046] First, when the power of the multifunction device 200 is turned on or the print job is completed as described above, a Yes is determined in S10, and it is determined whether the multifunction device 200 is in the contract start state (Activate) as described above by the conclusion of the contract as described above with reference to Fig. 2 (S20). If the multifunction device 200 is not in the Activate state, a No is determined, and this flow ends.

[0047] If it is activated, a Yes determination is made in S20, and cartridge type information of the ink cartridge 50 attached to the cartridge holder 51 is obtained via the communication unit 285 (S25). The process executed by the first display processing unit 210A in S25 is an example of a second acquisition process.

[0048] Thereafter, based on the cartridge type information acquired in S25, it is determined whether or not a normal cartridge 50 is attached to the cartridge holder 51 (S30). If a cartridge other than a normal cartridge 50 is attached, the determination is No, and this flow ends. S30 is an example of a determination step, the process executed by the first display processing unit 210A in S30 is an example of a first determination process, and the first display processing unit 210A that executes S30 is an example of a determination unit.

[0049] If a normal cartridge 50 is attached, S30 is judged as Yes, and the arrival time information of the contracted cartridge 50 stored in the arrival time information storage area 234 at this time is read and acquired (S40). If the contracted cartridge 50 has already arrived at the user's place, arrival time information indicating the arrival date and time and information to the effect that "arrived" are acquired, and if the contracted cartridge 50 has not yet arrived after being shipped and is still being delivered or has not yet been shipped, arrival time information indicating the expected arrival date and time is acquired. S40 is an example of an acquisition step, the process executed by the first display processing unit 210A in S40 is an example of a first acquisition process, and the first display processing unit 210A that executes S40 is an example of an acquisition unit.

[0050] <Processing by the delivery confirmation processing unit> The storage of the arrival time information in the above-mentioned arrival time information storage area 234 is performed by the above-mentioned delivery confirmation processing unit 210C of the processor 210. The flow of processing executed by this delivery confirmation processing unit 210C will be explained with reference to Fig. 4. Note that the flow in Fig. 3 and the flow in Fig. 4 are executed in parallel at the same time, for example, by a well-known method similar to "multitask processing" often performed in a computer OS or the like.

[0051] 4, first, in S41, it is determined whether a predetermined confirmation timing has arrived. That is, the current time indicated by the current time information from the timer circuit 260 is compared with the predetermined confirmation timing, and it is determined whether the current time is the same as the confirmation timing or whether the current item has passed the confirmation timing. Examples of the confirmation timing include the timing of powering on the multifunction device 200, the timing of the opening operation of the cover detected by the cover sensor 275, and the timing of the completion of a print job by the printing unit 290. Alternatively, the date and time at which the confirmation should be performed periodically may be individually determined in advance as the confirmation timing, or the confirmation timing may be determined to be performed at a predetermined cycle.

[0052] If the current time is the same as the confirmation timing or if the current item has passed the confirmation timing, a Yes is determined in S41, and as in S20 described above, it is determined whether the multifunction device 200 is in a contract start state (Activate) due to the conclusion of the contract (S42). If it is not Activated, a No is determined, and this flow ends. If it is Activated, a Yes is determined, and it is determined whether the service site of the delivery service company provided by the delivery management server 400 can be accessed (S43).

[0053] If the site is accessible, a Yes determination is made, and the service site is accessed to obtain arrival time information for the corresponding contract cartridge 50 (S44). For this access, the delivery confirmation processing unit 210C may obtain information from the service site via the delivery management server 400 over the network NT, or the delivery confirmation processing unit 210C may obtain information directly from the service site based on a URL. Thereafter, the arrival time information obtained in S44 is stored in the arrival time information storage area 234, thereby updating the content of the arrival time information stored in the arrival time information storage area 234 (S45), and this flow ends. The process executed by the delivery confirmation processing unit in S45 is an example of an update process.

[0054] On the other hand, if access is not possible in S43, a No decision is made, and the latest arrival time information stored in the arrival time information storage area 234 at this point is obtained and compared with the current time represented by the current time information from the timer circuit 260 (S46). If the current time has not passed the scheduled arrival date represented by the arrival time information, a No decision is made in S47 and this flow ends. If the current time has passed the scheduled arrival date, a Yes decision is made in S47, the content of the arrival time information stored in the arrival time information storage area 234 is changed to "arrived" (S48), and this flow ends.

[0055] <Processing when the MFP is turned on or when a print job is completed - Part 2> Returning to Fig. 3, when the arrival time information stored in the arrival time information storage area 234 by the delivery confirmation processing unit 210C is acquired in S40 as described above, it is judged whether or not the contract cartridge 50 has arrived based on the arrival time information (S50). That is, the current time indicated by the current time information of the timer circuit 260 is compared with the expected arrival date and time or the arrival completion date and time (hereinafter simply referred to as "arrival date and time") indicated by the arrival time information acquired in S40, and it is judged whether or not the current time is the same as the arrival date and time or has passed the arrival date and time. The arrival date and time is an example of the arrival time, and judging whether the current time is the same as the arrival date and time or has passed the arrival date and time is an example of judging the arrival of the arrival time, and the process executed by the first display processing unit 210A in S50 is an example of the second judgment process. As described above, the arrival of the contract cartridge 50 may not be determined based on whether the current time is the same as the arrival date and time or has passed the arrival date and time, but may be determined based only on whether the contract cartridge 50 has already arrived and information indicating that it has "arrived" is stored in the arrival time information storage area 234. If the contract cartridge 50 has not arrived, the result is No, and this flow ends.

[0056] If the contract cartridge 50 has arrived, S50 is judged as Yes, and a process for inquiring of the user as to whether or not to continue using the normal cartridge 50 as is is displayed on the display unit 240 (S60). FIG. 5(a) shows an inquiry screen 240A displayed on the display unit 240 at this time. The display content on this inquiry screen 240A is an example of usage confirmation information and also an example of consumables handling related information. S60 is an example of a display step, the process executed by the first display processing unit 210A in S60 is an example of a first display process, and the first display processing unit 210A executing S60 is an example of a display control unit.

[0057] For example, when the "No" button on the inquiry screen 240A is operated by operating the operation unit 250 of the multifunction device 200, S65 is judged as No, and a guide display is displayed on the display unit 240 to mount the contract cartridge 50 (S70). FIG. 5(b) shows the guide screen 240B displayed on the display unit 240 at this time. The user's intention expressed by operating the "No" button on the inquiry screen 240A is an example of the information to the effect that the continued use is not to be continued, and the display content on the guide screen 240B is an example of information to recommend replacement with the first consumable, and is also an example of information related to handling of consumables. S70 is also an example of a display step, the process executed by the first display processing unit 210A in S70 is also an example of a first display process, and the first display processing unit 210A executing S70 is also an example of a display control unit. After S70, this flow ends.

[0058] On the other hand, for example, when the "Yes" button on the inquiry screen 240A is operated by operating the operation unit 250 of the multifunction device 200, S65 is judged as Yes. At a predetermined timing thereafter, available amount information indicating the available amount of the normal cartridge 50 attached to the cartridge holder 51 at that time is acquired by a known method as described above (S75). The user's expression of intent by operating the "No" button on the inquiry screen 240A is an example of input information indicating that continued use is permitted, and the process executed by the first display processing unit 210A in S75 is an example of a third acquisition process.

[0059] When the available amount indicated by the acquired available amount information reaches a predetermined threshold value corresponding to the Empty state, which is a state in which the remaining amount of ink is low, S77 is judged as Yes, and a guidance display is displayed on the display unit 240 to install the contract cartridge 50, as in S70 described above (S80). The display content on the display unit 240 at this time is, for example, the same as that shown in FIG. 5B described above. The display content on the guidance screen 240B in this case is also an example of information recommending replacement with the first consumable, and is also an example of information related to handling of consumables. S80 is also an example of a display step, the processing executed by the first display processing unit 210A in S80 is also an example of a first display processing, and the first display processing unit 210A executing S80 is also an example of a display control unit. After S80, this flow ends.

[0060] <Processing when the opening and closing cover is opened> As another example of a case where consumable handling information is displayed, an example of processing performed by the second display processing unit 210B of the processor 210 when the above-mentioned opening / closing cover for opening and closing the cartridge holder 51 in the multifunction device 200 is opened will be described with reference to the flows in Figures 6 and 7. Note that the flows in Figures 6 and 7 and the flow in Figure 4 are executed simultaneously in parallel by a well-known method similar to "multitasking processing" that is often performed in, for example, a computer OS.

[0061] First, if the cover sensor 275 detects that the cover is open, a Yes is determined in S110, and similarly to S20, it is determined whether the multifunction device 200 is in a contract start state (Activate) (S120). If the multifunction device 200 is not in the Activate state, a No is determined, and a predetermined cover open screen (not shown) indicating that the cover is open is displayed on the display unit 240 (S210), and then this flow ends.

[0062] If it is Activated, S120 is judged as Yes, and similarly to S40, the arrival time information of the contract cartridge 50 stored in the arrival time information storage area 234 at this time point is acquired (S130). S130 is an example of an acquisition step in this case, the process executed by the second display processing unit 210B in S130 is an example of a first acquisition process, and the second display processing unit 210B that executes S130 is an example of an acquisition unit.

[0063] Based on the arrival time information acquired in S130, it is determined whether or not the contract cartridge 50 has arrived, similar to S50 (S140). That is, the current time indicated by the current time information of the timer circuit 260 is compared with the arrival date and time indicated by the arrival time information acquired in S130, and it is determined whether or not the current time is the same as the arrival date and time or has passed the arrival date and time. The arrival date and time is an example of the arrival time, and determining whether the current time is the same as the arrival date and time or has passed the arrival date and time is an example of determining the arrival of the arrival time, and the process executed by the second display processing unit 210B in S140 is an example of a second determination process.

[0064] If the contract cartridge 50 has arrived, the determination is Yes, and similarly to S25, cartridge type information of the ink cartridge 50 mounted in the cartridge holder 51 is acquired (S145). The process executed by the second display processing unit 210B in S145 is an example of a second acquisition process. Thereafter, based on the acquired cartridge type information, it is determined whether or not the contract cartridge 50 is mounted in the cartridge holder 51 (S150). If the contract cartridge 50 is mounted, the determination is Yes, and the above-mentioned S210 is executed to end this flow. S150 is an example of a determination step, the process executed by the second display processing unit 210B in S150 is an example of a first determination process, and the second display processing unit 210B that executes S150 is an example of a determination unit.

[0065] If the contract cartridge 50 is not installed, the result is determined as No, and a guidance display is displayed on the display unit 240 to install the contract cartridge 50, in other words, to replace the normal cartridge 50 in the cartridge holder 51 with the contract cartridge 50, as in S70 (S160). The display contents on the display unit 240 at this time are, for example, the same as those shown in FIG. 5(b) above. The display contents on the guidance screen 240B in this case are also an example of the information recommending replacement with the first consumable, and are also an example of the information related to handling of consumables. S160 is also an example of a display step, the processing executed by the second display processing unit 210B in S160 is also an example of the first display processing, and the second display processing unit 210B executing S160 is also an example of a display control unit. If the user performs an appropriate confirmation operation on the above guidance display in S160, for example, via the operation unit 250 (S170), this flow ends via the above-mentioned S210.

[0066] On the other hand, if the contract cartridge 50 has not arrived in the above-mentioned S140, the result is No, and the cartridge type information of the ink cartridge 50 mounted in the cartridge holder 51 is acquired (S172) in the same manner as in S25 and S145. The process executed by the second display processing unit 210B in S172 is also an example of a second acquisition process. Then, based on the acquired cartridge type information, it is determined whether or not the contract cartridge 50 is mounted in the cartridge holder 51 (S175) in the same manner as in S150. S175 is also an example of a determination step, the process executed by the second display processing unit 210B in S175 is an example of a first determination process, and the second display processing unit 210B that executes S175 is an example of a determination unit. If the contract cartridge 50 is mounted, the result is Yes, and based on the arrival time information acquired in S130, the expected arrival date and time of the next contract cartridge 50 is displayed on the display unit 240 (S200). FIG. 5(c) shows an expected arrival display screen 240C displayed on the display unit 240 at this time. The display contents on the arrival schedule display screen 240C are also an example of consumables handling related information, S000 is also an example of a display step, the process executed by the second display processing unit 210B in S200 is also an example of a first display process, and the second display processing unit 210B executing S200 is also an example of a display control unit. When the user performs an appropriate confirmation operation on the arrival schedule display in S200, for example, via the operation unit 250 (S205), this flow ends.

[0067] On the other hand, if the contract cartridge 50 is not attached in S175, the result is determined as No, and the expected arrival date and time of the next contract cartridge 50 is displayed on the display unit 240 based on the arrival time information acquired in S130, as in S200 (S180 in FIG. 7). The display content on the display unit 240 at this time is, for example, the same as that shown in FIG. 5(c) above. The display content on the expected arrival display screen 240C in this case is also an example of consumables handling related information corresponding to the arrival time not yet arriving. S180 is also an example of a display step, the process executed by the second display processing unit 210B in S180 is also an example of a first display process, and the second display processing unit 210B executing S180 is also an example of a display control unit.

[0068] When the user performs an appropriate confirmation operation for the above display in S180, for example, via the operation unit 250 (S190), available amount information indicating the available amount of the normal cartridge 50 mounted in the cartridge holder 51 at this time point is acquired (S191), similarly to S75. The process executed by the second display processing unit 210B in S191 is an example of a fourth acquisition process.

[0069] When the available amount indicated by the acquired available amount information reaches a predetermined threshold corresponding to an Empty state where the ink is about to run out, S192 is judged as Yes, and a process for inquiring the user as to whether or not to replace the cartridge with a new normal cartridge 50 is displayed on the display unit 240 (S193). FIG. 5(d) shows an inquiry screen 240D displayed on the display unit 240 at this time. The display content on this inquiry screen 240D is an example of replacement confirmation information and also an example of consumables handling related information. S193 is also an example of a display step, the process executed by the second display processing unit 210B in S193 is also an example of a first display process, and the second display processing unit 210B executing S193 is also an example of a display control unit.

[0070] For example, when the "No" button on the inquiry screen 240D is operated by operating the operation unit 250 of the multifunction device 200, S194 is judged as No, and the display of the predetermined special information corresponding to the contracted cartridge 50 is started on the display unit 240 (S195). FIG. 8 shows the special information display screen 240E displayed on the display unit 240 at this time. As shown in the figure, the special information display screen 240E displays the name and status information of the multifunction device 200, as well as the details of the concluded contract, such as the amount, the method of counting the number of printed sheets, and options. These display contents are originally displayed only when the contracted cartridge 50 corresponding to the above contract is mounted in the cartridge holder 51, but in this S195, they are displayed exceptionally because the contracted cartridge 50 has not yet arrived despite the conclusion of the contract. The display contents on this special information display screen 240E are an example of special information, and the process executed by the second display processing unit 210B in S195 is an example of the second display process.

[0071] After S195, similar to S140, based on the arrival time information acquired in S130, it is determined whether or not the contract cartridge 50 has arrived (S196). If it has arrived, a Yes determination is made, and the display of the special information on the display unit 240 that began in S195 ends (S197), and the process returns to S160.

[0072] On the other hand, if, for example, the "No" button is operated on the inquiry screen 240D, S194 is judged as Yes, the open state of the opening / closing cover is detected as in S110, S198 is judged as Yes, and this flow ends after S210 in FIG. 6 is performed.

[0073] <Effects of the embodiment> As described above, the multifunction device 200 of this embodiment has the cartridge holder 51, the printing unit 290, the display unit 240, and the processor 210, and is operable based on the contents of the contract concluded with the contracting party regarding the cartridge 50 used for printing in the printing unit 290. In S40 and S130, arrival time information is acquired for the contract cartridge 50 corresponding to the contents of the contract, which is to be delivered to the multifunction device 200. In S30, S150, and S175, the type of the cartridge 50 attached to the cartridge holder 51 is determined. The acquired arrival time information of the contract cartridge 50 and consumables handling related information corresponding to the above-mentioned judgment result are displayed on the display unit 240 in S60, S70, S80, S160, S200, S180, and S193 (see also FIGS. 5(a) to (d)). According to this embodiment, the arrival time information corresponding to the delivery status of the contract cartridge 50 after the contract is concluded and the above-mentioned determination result related to the type of the installed cartridge 50 are displayed on the display unit 240, thereby making it possible to provide the user with appropriate information.

[0074] In this embodiment, in particular, in S25, S145, and S172, type information of the cartridge 50 attached to the cartridge holder 51 is acquired. In S30, S150, and S175, the type of the cartridge 50 is determined based on the type information acquired in S25, S145, and S172. According to this embodiment, the type of the cartridge 50 can be reliably determined based on the type information acquired from the cartridge 50.

[0075] In this embodiment in particular, in S50 and S140, it is determined whether or not the arrival time of the contracted cartridge 50 has arrived, in other words, whether or not the contracted cartridge 50 has arrived. If the arrival time has arrived, in S60, S70, S80, S160, S200, S180, and S193, consumables handling related information corresponding to the arrival of the contracted cartridge 50 is displayed on the display unit 240. According to this embodiment, if a commercially available cartridge 50 is already installed before the arrival of the contract cartridge 50, usage confirmation information is displayed as to whether or not to continue using it (S60, see FIG. 5(a)), and if a new commercially available cartridge 50 is installed after the arrival of the contract cartridge 50, replacement recommendation information is displayed to recommend that it be replaced with the contract cartridge 50 (S70, S80, see FIG. 5(b)), thereby improving user convenience.

[0076] Furthermore, particularly in this embodiment, if it is determined in S30 that a normal cartridge 50 is attached to the cartridge holder 51, in S60, usage confirmation information regarding whether or not the attached normal cartridge 50 can be continued to be used is displayed on the display unit 240 (see FIG. 5(a)). According to this embodiment, if a normal cartridge 50 has already been installed before the arrival of the contract cartridge 50, usage confirmation information as to whether or not to continue using the cartridge is displayed, thereby making it possible to improve convenience for the user.

[0077] Furthermore, particularly in this embodiment, when information to the effect that continued use is not permitted is obtained from the user in response to the display of usage confirmation information regarding whether or not continued use of the normal cartridge 50 is permitted, in S70, replacement recommendation information recommending replacement with a contract cartridge 50 is displayed on the display unit 240 (see FIG. 5(b)). According to this embodiment, by displaying replacement recommendation information that recommends replacing the normal cartridge 50 with the contract cartridge 50 upon arrival of the contract cartridge 50, it is possible to improve user convenience.

[0078] Furthermore, particularly in this embodiment, when information indicating that continued use is permitted is obtained from the user in response to the display of the use confirmation information regarding whether or not continued use of the normal cartridge 50 is permitted, in S75, usable amount information of the normal cartridge 50 mounted in the cartridge holder 51 is obtained as needed. When the usable amount information reaches a predetermined threshold, in S80, replacement recommendation information recommending replacement with a contract cartridge 50 is displayed on the display unit 240 (FIG. 5(b)). According to this embodiment, the user's intention to continue using the regular cartridge 50 even after the arrival of the contract cartridge 50 is respected, and replacement recommendation information is displayed recommending replacement with the contract cartridge 50 when the use of the continued regular cartridge 50 has almost come to an end, thereby improving user convenience.

[0079] Furthermore, particularly in this embodiment, if it is determined in S150 that a normal cartridge 50 is attached to the cartridge holder 51, in S160 replacement recommendation information recommending replacement with a contract cartridge 50 is displayed on the display unit 240 (see FIG. 5(b)). According to this embodiment, when a regular cartridge 50 is installed even though a contract cartridge 50 has already arrived, replacement recommendation information is displayed on the display unit 240 to alert the user, thereby improving user convenience.

[0080] In this embodiment, in particular, in S140, it is determined whether or not the arrival time of the contract cartridge 50 has arrived, in other words, whether or not the contract cartridge 50 has arrived. If the arrival time has not arrived, in S200, S180, and S193, consumables handling related information corresponding to the fact that the contract cartridge 50 has not arrived is displayed on the display unit 240. According to this embodiment, for example, expected arrival information indicating the expected arrival date of the contract cartridge 50 is displayed (see FIG. 5(c)), and when a commercially available cartridge 50 is loaded and its use is completed, replacement confirmation information is displayed as to whether or not to replace it with another commercially available cartridge 50 (see FIG. 5(d)), thereby improving user convenience.

[0081] Furthermore, particularly in this embodiment, if it is determined that the arrival time for the contract cartridge 50 has not arrived, in S193, replacement confirmation information for confirming whether to replace the installed normal cartridge 50 with a new normal cartridge 50 is displayed on the display unit 240 (see FIG. 5(d)). According to this embodiment, when a regular cartridge 50 has already been installed and used before the arrival of the contract cartridge 50 and the regular cartridge 50 is about to reach the end of its life, replacement confirmation information is displayed asking whether or not to install another regular cartridge 50 without waiting for the arrival of the contract cartridge 50, thereby improving user convenience.

[0082] In particular, in this embodiment, when the contract cartridge 50 has not arrived and the user is forced to use the normal cartridge 50 instead, in S191, usable amount information of the normal cartridge 50 mounted in the cartridge holder 51 is acquired. When the usable amount information reaches a predetermined threshold, in S195, special information corresponding to the contract cartridge 50 is displayed on the display unit 240. When a contract is concluded, the user should normally enjoy benefits in terms of costs, etc., by using the contract cartridge 50. According to this embodiment, in order to deal with the situation in which the user is unable to enjoy such benefits due to the non-arrival of the contract cartridge 50, in S195, special information that would not normally be displayed unless the contract cartridge 50 is being used is displayed to the user, thereby making it possible to alleviate the user's disadvantageous state to some extent.

[0083] Furthermore, particularly in this embodiment, S30 and S40 are performed when the multifunction device 200 is turned on or when printing by the printing unit 290 is completed, and S130, S150, and S175 are performed when the opening and closing cover is opened and closed, and based on the respective results, the above-mentioned consumable handling related information is displayed in S60, S70, S80, and S160, S200, S180, and S193. According to this embodiment, when the power is turned on to start using the multifunction device 200, when printing is completed, when the user opens and closes the opening / closing cover to install or replace the cartridge 50, etc., the display unit 240 displays information corresponding to the arrival time information and the determination result related to the type of cartridge 50, thereby providing the user with appropriate information.

[0084] 4 is performed at a predetermined cycle, the arrival time information is written sequentially to the arrival time information storage area 234, and the stored contents are updated. Then, the updated arrival time information is read and acquired from the arrival time information storage area 234 by S40 or S130, and the consumables handling related information is displayed in S60, S70, S80 or S160, S200, S180, S193 based on the read contents. According to this embodiment, a display is made according to the determination result relating to the type of cartridge 50 and arrival time information that is updated at a predetermined interval, making it possible to provide the user with appropriate information.

[0085] In particular, in this embodiment, as shown in S44 to S48 of FIG. 4, the above consumable handling related information is displayed in S60, S70, S80 or S160, S200, S180, S193 based on the latest arrival time information stored in the arrival time information storage area 234. According to this embodiment, even if, for example, arrival time information based on S45 executed in the latest cycle cannot be obtained in S40 executed by the delivery confirmation processing unit 210C, arrival time information based on S45 executed in the cycle immediately prior thereto can be obtained, and a display can be made according to the obtained arrival time information and the determination result relating to the type of cartridge 50, thereby providing the user with appropriate information.
